Page 15: Operation
3 Operation If you are not familiar with the 2D-CCD / 3D-VLEED detector, it is recommended that you read Chapter 5, “ Spin detector principles ” before continuing. The 2D–CCD / 3D-VLEED Detector effectively consists of three detectors in one: 1.
Page 16 To run an experiment with a template: 1. Switch on the power supplies. 6. Start SpecsLab Prodigy. 7. In the Experiment Editor, Click a template in the Load Template section. The following example shows the UPS Spin Step Profile template. Figure 4.

If you make changes to a template and want to use these in future, you can save your experiment as a template: Click the icon in the top section of the experiment (just below the Description field) and Save As select Template.
Page 18: Templates For The 2D-Ccd / 3D-Vleed Detector
The optimum operating voltages for the CEMs of the Ferrum detector are determined by SPECS during testing and are included in the test report. As the detector ages, the gain is reduced and you need to increase the detector voltage to compensate. See the Focus Ferrum spin detector manual for more information about life time and ageing of the CEMs.
Page 19: Scattering Energy Scan
See "Using the Image View to Display Results" on in Section 3.4 for instructions on viewing the data. 3.1.3 Scattering Energy Scan A Scattering Energy (SE) scan records the intensity of electrons scattered from the scattering crystal as a function of the scattering energy, i.e., the energy the electrons have at the surface of the scattering crystal.
Page 20: Ups Spin Step Profile
This template is essentially identical to the PHOIBOS 1D Adjustment template, except that the SpinDetector Control is set to Channel 2. 3.1.5 UPS Spin Step Profile This temple is used to carry out actual measurements with the spin detector. The following sections describe the template in greater detail. It is useful to know the function of the components in the schedule if you want to modify the template.
Page 21: Viewing Results
To use the detector in CCD mode: 1. When defining an experiment in the Experiment Editor, select the PHOIBOS CCD analyzer. 2. Define the excitation source in the Experiment Editor. 3. Create a Spectrum group. 4. Start the measurement by clicking Caution! The intensity of the detected signal is much higher than for the spin detector.

The input parameters allow you to alter the operation. The table below lists all the input parameters for the Spin Asymmetry for VLEED operation.
Page 23: Using The Image View To Display Results
Using the Image View to display results Scattering energy (SE) scans and detector voltage scans produce data that cannot be conveniently shown in the Plot View. The best way to view the results is in the Image View: Select Views/Image View from the menu bar. The Image View will open. Double-click the spectrum in the data browser to select it.
Page 24: Troubleshooting
4 Troubleshooting The information in this chapter can help you identify and solve problems that may occur. Checking the functionality of the PCU 300 preamplifier can help confirm if the CEMs in the Ferrum detector are working correctly. A set of tables contain pin-outs of the electronics specific to the 2D–CCD / 3D-VLEED Detector.
Page 25: Discriminator Threshold
Discriminator threshold The discriminator threshold sets the level at which pulses from a CEM are counted or ignored. It is desirable to have this level as low as possible, so that all pulses are detected. Under some circumstances, it is necessary to adjust the threshold to reduce the counted signal. This may be performed to reduce noise from a channel, or to compensate for aging differences between channels.

The 2D-CCD / 3D-VLEED Detector is mounted on the detector flange of a PHOIBOS electron energy analyzer. Figure 13 shows a diagram of the PHOIBOS electron energy analyzer with the 2D-CCD / 3D- VLEED Detector attached. Electrons emitted from the sample pass through the analyzer lens and hemispherical analyzer for energy resolution.
Page 31: Analyzer
Coil 1 Coil 2 Target Ferrum detector Sample Figure 13. Principle of operation. 5.1.1 Analyzer The electrons for the spin detector do not travel along the center of the hemispherical analyzer, but rather closer to the inner hemisphere. The CCD detector is located at a radius larger than the mean radius analyzer.

installed. They serve to shape the beam for high pass energies in the analyzer. Electrons scattered at these apertures are stopped from reaching the 90° deflector by a retarding potential applied to the next lens L5A. The triplet L4A, L5A, L4B thus serves as a repeller for scattered electrons.
Page 33: 90° Deflector
The purpose of the coil lens is to rotate the spin polarization vector, but inevitably the coil also has a focusing effect. Since the focusing is proportional to the square of the coil current, it is possible to rotate the spin polarization vector (and the image) while keeping the focusing power constant by changing the direction of the coil current.
Page 34: Retardation Stage
5.2.1 Retardation stage Following the 90° deflector, the electron beam passes a retardation stage consisting of the lens tubes L4C (on the same potential as L4B), L5B, L4D and L4E. L4E is the entrance of the Ferrum detector. The electrons enter the spin Ferrum detector with a fixed kinetic energy of 50 eV.

CCD. High-performance CCD sensors like those used for the SPECS CCD detector have extremely good linearity. Deviations from linearity are often less than a few tenths of a percent for over five orders of magnitude.
Page 44: Dynamic Range
Dynamic range Thermally excited electrons in the silicon lattice of the CCD chip are counted as a signal. Thermal noise charges, again expressed as electrons, are generated in a CCD camera regardless as to whether it is exposed to light or complete darkness. Thermal noise is temperature dependent.

Page 48: Maximizing The Lifetime Of Mcps
The MCPs show a slow decrease in sensitivity after prolonged use. For that reason, • you need to increase the detector voltage periodically. 6.10 Maximizing the lifetime of MCPs MCPs are delicate devices and need careful handling to ensure long lifetime and good performance.
Page 49: Degassing The Detector
MCPs without a solid glass border should be handled very carefully, taking great care to touch only the outer edges of the plate. Please note that the MCP type used for the SPECS CCD detector is extra thin (L/D = 50) because of their better imaging quality. Unfortunately this MCP type is also extremely fragile.
Page 50: Phosphor Screen
This section presents some data acquired using SPECS CCD detectors as examples of the flexibility of this detector. The Cu(111) surface state was measured using a PHOIBOS 100 analyzer and the SPECS UVS 10/35 helium discharge lamp. The data acquisition time was 200 seconds for the whole image.

Page 54: Power Supplies
7 Power Supplies The standard power supply for PHOIBOS analyzers and detectors is the HSA 3500plus. The 2D-CCD / 3D-VLEED Detector requires a second, modified, HSA 3500plus Spin. This chapter contains information about this additional power supply. Where appropriate, you are referred to other manuals for further information.

Page 60: Mounting The Ccd/Rotator/Deflector Part
Figure 31. Venting with dry nitrogen. Caution! Both parts are heavy and fragile. Use a crane when mounting the detector. Caution! The two parts cannot be pre-assembled, but must be mounted onto the system in sequence. Neither is it possible to remove the two parts from the PHOIBOS analyzer as one unit. Doing so will damage the detector.
Page 61 Figure 32. The CCD/deflector/rotator part supported from the crane. Check that the multi-channel plate (MCP) is free from dust, see Figure 33. Any dust must be removed with the air brush delivered with the detector. Caution! Do not touch the surface of the MCP with any objects. Manual V2.docx | Status 10.12.2015 | Version 1.0...
Page 62 Alignment pin Figure 33. Checking the MCP for dust. There is an alignment pin at the side of the top disc, see Figure 33, which assures that the orientation of the detector is correct. This pin must fit into a groove in the base plate of the PHOIBOS analyzer.
Page 63 Support rods Figure 34. View of the support rods as seen through the CF 200 flange. Before tightening the bolts, check that the CF 200 flange is parallel with the plane defined by the detector and lens of the PHOIBOS, see Figure 35. Figure 35.
Page 64: Mounting The Ferrum Detector Part
A.2.2 Mounting the Ferrum detector part Caution! Use dry nitrogen for venting the detector hardware. Vent the Ferrum part with the valve on the protective cap, as shown in Figure 31 . Check that the Mu-metal screen in the pump port is in place. It should look as in Figure 36 . Figure 36.
Page 65 Figure 37. The end of the deflector lens system. Support the component from the crane, as shown in Figure 38. Be careful that the component hangs horizontally. Check that the fingers of the Mu-metal shield fits tightly into the housing of the CCD/rotator/deflector part. The fingers can be bent slightly outwards if necessary.
Page 66 Figure 38. The Ferrum detector supported from the crane. Mount a fresh CF 200 gasket and carefully slide the adapter lens into the CF 200 flange of the CCD/rotator/deflector part. Check that the pumping port is aligned correctly and tighten the bolts, see Figure 39.
Page 67: Optimizing The Signal
• Before starting the optimization procedure, you should check the parameters used when the detector was tested at SPECS. These factory optimized parameter values are stated in the Test Report. Once the correct position of the excitation source relative to the PHOIBOS lens and the optimum deflector values have been found, it should be sufficient to optimize the position of the sample for each measurement.
Page 68: Adjusting The Deflector/Rotator Lens
Successively reduce the entrance aperture size and iris opening while adjusting the electron gun deflectors so that the intensity is optimal. At the end optimize the signal with the Slit6/open set and the iris fully closed. The detector image will be a narrow stripe at angle zero, as shown in Figure 40. Check that the stripe gets wider in symmetrical fashion, when the iris is opened.
Page 69 Set Voltages In the SpinDetectorControl device, click on , see Figure 44. Set the parameter values from the SPECS Test Report as start values. Typical voltages are Apply shown in Table 11. Set the voltages and click Figure 41. Screenshot of the Device Controls window for the Spin Detector Control in SpecsLab Prodigy.
Page 70 Figure 42. Screenshot of the Device Controls window for the PHOIBOS 1D in SpecsLab Prodigy. Also change the setting RotL from +1 to -1 and back. The intensity should change at most 5% when changing rotation direction, see Figure 43. Rot L -1 Rot L +1 Figure 43.
Page 71: Adjusting The Beam Alignment For The Total Intensity Channel
A.3.3 Adjusting the beam alignment for the total intensity channel Once the deflector/rotator lens settings have been optimized, go on to adjust the deflectors in the Ferrum Spin Detector, i.e., Lens1DeflectionX, Lens1DeflectionY, Lens3DeflectionX and Set Voltages Lens3DeflectionY. Change the values under SpinDetector Control and click Apply, see Figure 41.
Page 72: Alignment With Phosphor Screens
A.4 Alignment with phosphor screens The following procedures are normally only carried out at SPECS. They are described here for reference purposes. Manual V2.docx | Status 10.12.2015 | Version 1.0...
Page 73: Alignment Of Spin Deflector 1 And The Rotator Lens With The Alignment Camera
A.4.1 Alignment of spin deflector 1 and the rotator lens with the alignment camera Use the electron gun with the beam positioned as described in section A.3.1. It requires a very high electron current to see an image with the alignment camera. Operate the analyzer in the RotCalib lensmode with E 20 eV, E = 160 eV.
Page 74 Figure 46. Image from the alignment camera with the exit slit and RotL +1. With RotL is set to -1, the image should rotate 45°, as shown in Figure 47. This corresponds to a rotation of the spin polarization by 2x45° = 90° around the lens axis. The blue stripe does not go exactly through the center of rotation, but the movement of the image when RotL is changed should be minimized.
Page 75: Alignment Of Spin Deflector 2 With A Phosphorous Screen
A.4.2 Alignment of spin deflector 2 with a phosphorous screen With the vacuum system vented, remove the Ferrum detector part from the CCD/deflector/rotator part. Mount the small phosphorous screen on the end of the deflector lens system. Mount the CF 200 flange with a CF 40 window instead of the Ferrum detector. This flange with window is included in the delivery.
Page 76: Camera Alignment
This initial camera positioning is performed by SPECS—you will only need to perform these steps if you remove the camera from the holder. As such, this is not a "routine" procedure that needs to be performed each time you mount the camera on the detector.
Page 77 Figure 49. Loosening the ring nut on the camera holder. Hold the main body of the camera and rotate it gently. The camera should be oriented so that the mounting plate is parallel to the angular adjustment screw. Figure 50 shows PCO Pixelfly camera mounted on the holder. There is a similar mounting plate on the PCO 1300 cameras.

Page 79 Figure 51. Initial signal in camera alignment. Change the exit slit to position A ("slits"). The image will show a number of lines. Turn the camera to get the position as good as possible. The lines should be vertical. It is sufficient to get the camera image "nearly" right—you can perform some fine tuning later to improve the angular setting.
Page 80: Setting The Focus
Figure 52. Image after rough angular adjustment of the camera. 10. Remove the camera holder from the detector and tighten the ring nut, being careful not to turn the camera. 11. Mount the camera and check the image. With an image like that in Figure 52, you need to make the following corrections: Adjusting the focus in order to obtain a sharp image.
Page 81: Set X-Y
Figure 53. Adjusting the focus. Turn each of the four adjustment nuts by an equal amount. This will move the camera up or down without affecting the X-Y position. The gap between the lowest plate and the rest of the holder should be approximately 5 mm. Check the camera image in CCD Acquire at regular intervals.
Page 82: Fine Angle Adjustment
A.5.4 Fine angle adjustment The angular position of the camera in the holder is set by SPECS before delivery. However, some small adjustments may also be necessary in order to get correct vertical lines in the image.
Page 83 Figure 55 shows the mechanism for the fine angular adjustment. It is helpful to refer to this picture while following the procedure below. Figure 55. Fine angular adjustment. To set the fine angular adjustment: Release the two fixing bolts. Release the locking nuts on the angular adjustment screw. The screw should be able to rotate freely.
Page 84 The distance between the slits should be 8 mm. If the slit-slit distance is not correct, the camera magnification needs to be changed. See the Manual Software 2D/3D detectors for information on how to set the camera magnification. Figure 56. Image from a correctly aligned camera. Manual V2.docx | Status 10.12.2015 | Version 1.0...
