The CS021 offers orthogonal xyz positioning with high load capacity in a compact and robust package. It combines 2 CBS10 positioners for xy motion with a CLA2601 positioner for vertical motion. The latter allows the CS021 to take loads up to 1kg. Sensors with absolute position output can be fitted on all axes when closed loop positioning is required. The detachable reference frame offers users a rigid and stable surface to attach for instance probes or cooling braids close to the sample table. It is made of gold plated OFHC for highest thermal conductivity.
|Type of motion||-||x, y, z, orthogonal|
|Step range||mm^3||max 10 x 10 x 5|
|Scan range @ ambient *||µm^3||10 x 10 x 10|

|X and Y positioner (including scanning) **||-||CBS10|
|Z positioner ***||-||CLA2601|
|Z scanning actuator||-||piezo ceramic|
|Z-scanner sensitivity @ ambient||nm/V||66|
|Z-scanner sensitivity @ 4 K||nm/V||13|
|Endstops ****||-||xy +/-5mm and z +/- 3mm|
|Main construction materials||-||Titanium, Aluminium, Stainless steel|
|Scanner module for z-scanner||-||CADM2 or PSM, PSMIL|
|* Specified scan ranges assume use of CADM2 -20 to +130V, 10 bits resolution, setpoint rate approx. 10Hz. Alternative for z-scanner only: PSM amplifier with PSMIL -20V to +130V. By disconnecting the PSMIL high voltage bipolar operation is possible to increase the range. This is only allowed at deep cryogenic temperatures and -150V to +150V is not to be exceeded!|

|**** xy endstops can be touched without problems. Touching z endstops is ideally avoided and can be prevented by using the RLS position feedback option. Touching them will not cause damage but could require manual action to free it.|
The RLS (Resistive Linear Sensor) is a resistive based sensor that can be added to selected positioners for position feedback. A wiper slides over a resistive track and the measured voltage is a measure of position. Resolution is determined by electrical noise and length of the resistive track. It is an absolute sensor, which means that it will give the actual position, even after recovering from a power shutdown. The RLS requires the RSM electronics module as voltage source and position readout. More info can be found in the Downloads section.
HV rated positioners can realistically be considered compatible with pressures as low as 1E-8 mbar. Lower pressures can be achieved by prolonged baking of positioners in vacuum at 100-150 deg C, depending on the type of positioner. Upon request JPE can provide such service at additional costs.
