Page 7: Chapter 1 - Introduction
Welcome to the user manual for the SPECS KolibriSensor Starter Kit. The Starter Kit enables evaluation of a KolibriSensor without the need to mount it in a micro- scope. The KolibriSensor has proven its qualities in the SPECS Aarhus SPM 150 and the SPECS JT-SPM as well as being suited for use in custom microscopes. - Page 8 There must be no condensed water on the equipment. Atmospheric pressure: Ÿ 800–1200 mbar Air conditioning is advisable in order to ensure the ambient requirements, especially for dis- sipating heat produced by the equipment.

In case of missing or damaged parts, please contact SPECS immediately. Figure 1: Parts supplied in Starter Kit delivery The SPECS KolibriSensor Starter Kit consists of the following components, as pictured in Figure 1: KolibriSensor V2.0 | June 17, 2014... -

Oscillation Controller Figure 2: Electrical connections for the Starter Kit The I connector is connected to the tip of the KolibriSensor and is therefore not used for driv- ing the sensor oscillation. Caution! Make sure the attenuators are fitted as shown in Figure 2. These prevent pos- sible damage to the sensor induced by too high excitation amplitudes. -
Page 11: Chapter 3 - Operation
Inserting a KolibriSensor into the Test Stage The KolibriSensor is stored in a transport package when it is not in use. SPECS supplies a spe- cial pair of tweezers for handling the KolibriSensor. These are shaped so that they will correctly grip the KolibriSensor: this greatly simplifies the process of inserting and removing the sensor. -
Page 12: Setting Up Oscillation Parameters
Setting Up Oscillation Parameters The following procedure describes the normal operation of a KolibriSensor using the Starter Kit and the Nanonis Oscillation Controller. The resonant frequency and Q factor of the sensor are measured. The Nanonis Oscillation Controller is set up using typical oscillation parameters to drive the sensor oscillation at the resonant frequency with controlled amplitude. -

Page 16: Removing A Kolibrisensor From The Test Stage
Removing a KolibriSensor from the Test Stage To remove the KolibriSensor from the test stage: 1. Remove the sensor by gripping it below the guidance ring with the tweezers and pulling it out of the KolibriReceptor. -
Page 17: Chapter 4 - Technical Details
Figure 12: KolibriPreamp The nominal conversion factor of the KolibriPreamp used with the KolibriSensor is 0.7 V/nm. This means that an oscillation amplitude of 1 nm of the oscillating KolibriSensor induces an out- put voltage from the KolibriPreamp of 0.7 V. -
Page 18: Attenuators
The Starter Kit is supplied with two 20 dB attenuators. These are connected in series between the output of the Nanonis Oscillation Controller and the Excitation input of the test stage. The attenuators protect the KolibriSensor from excessive drive levels and improve the signal to noise ratio of the excitation signal.
