Page 5: Description
XR100CR SiPIN User Manual -B3 Description Core detector technology Amptek provides a family of high performance, compact X-ray detectors and associated signal processing electronics. The radiation detectors are custom photodiodes, including the traditional Si-PIN diodes, Silicon Drift Detectors (SDDs), and CdTe Schottky diodes. The detector is mounted on a two-stage thermoelectric cooler along with the key preamplifier components. -

Page 7: Efficiency
XR100CR SiPIN User Manual -B3 Efficiency The intrinsic efficiency is the probability that an X-ray incident on the detector window (in the active region) will interact in the detector and thus deposit its energy, creating a signal pulse. It is the product of (a) the probability of transmission through the window and (b) the probability of interacting in the 500 m silicon depth (the detector is fully depleted). - Page 8 XR100CR SiPIN User Manual -B3 Electronic X-Ray Energy (keV)

Page 12: Construction
XR100CR SiPIN User Manual -B3 Construction The detector element (the SiPIN itself) is mounted on a substrate, which is mounted on a thermoelectric cooler, which is attached to the TO-8 header. A multilayer collimator is mounted on the detector to mask the edges of the active volume. Interactions outside the active volume can cause spectral anomalies. -

These traces illustrate typical output pulses with a SiPIN detector, measured using 5.89 and 22.1 keV X-rays. Each X-ray interaction results in a negative going step of ~1 mV/keV. Preamplifier Reset Signal This trace also shows the preamp output but on a different voltage and Preamplifier output. -

The PX5 includes a power supply for the thermoelectric cooler which provides its own regulation. When the XR-100 SI-PIN is to be used with a PX5, set the XR-100CR control to maximum cooling and let the PX5 regulate. If the PX5 and XR-100CR are set to different temperature set points, whichever set point... - Page 16 XR100CR SiPIN User Manual -B3 The figure above shows how to adjust the controller on the XR-100CR. Remove the top cover and adjust the R39 pot to achieve the desired TMP SET value. This is the set point temperature. It reads in mV with the calibration curve shown in the next section.

3) Connect the LEMO CONNECTOR cable to the XR-100CR, according to the pin assignments given in section 6.1 of this manual. 4) Attach the OUTPUT of the XR-100CR to the INPUT of the signal processor. A BNC connector is provided on the rear panel of the XR-100CR. The output pulses of the XR-100CR are NEGATIVE. -

The reset frequency will decrease as the detector cools. 11) Once the temperature gets below -40 °C the performance of the XR-100CR system will not change with a temperature variation of a few degrees. Now the XR-100CR is fully operational. -

Look for interference noise. Connect the XR-100CR output to its signal processor and this to an oscilloscope. Remove all X-ray sources. Look for periodic noise pick-up on the scope by changing the time-base dial on the scope back and forth. -
