Cryogenic Probe Station
Model 122 Kilimanjaro from High Precision Devices (HPD)
The cryogenic probe station Model 122 Kilimanjaro provides a low temperature platform with a closed helium cycle for device probing. Common probe stations use manipulator arms fixed at room temperature which heat up the sample upon contact. So the real temperature of the sample is unknown. In HPD Model 122 the probes are moved via low-temperature piezo positioners who are thermally anchored at 4 kelvin. This way, the manipulators do not create a heat link and the sample temperature is always known.
|4 K cooling platform|
|1.5 W cryocooler with the He-4 pot for <50 mK stability|
|Optical access to the sample space|
|Large sample space: 10” diameter, 6.5” height|
|Various feedthroughs available|
Capacity for wires and/or cables set up for 4 high-speed (2.92 or SMA) feedthroughs per quadrant (16 total), plus 25 extra DC lines.
The system can be customized to your individual requirements.
Measurement of chips
By default, the system can scan 20 mm chips. Other sizes are possible upon request.
Optoelectronic chips can easily be probed and measured.
Astrophysical experiments require very sensitive detectors with high band widths. A bolometer can provide these properties. In order to suppress noise and maximize sensitivity, the bolometer is cooled down to the millikelvin range.
Quantum transport phenomena are the target of a strongly growing field of research. As the stability of a quantum system dramatically increases at low temperatures, most setups use a cryostat to cool the system to a few kelvin or millikelvin.
