Vacuum Probe Station – ARS PS-L Flow Cryostat

The ARS PS-L Flow Cryostat Probe Station is a four-probe electrical characterization tool with vacuum and cryogenic capabilities.

Both liquid Helium and Nitrogen can be used, and a temperature controller allows to set the chamber temperature to a desired value.

A quartz window allows to monitor the sample and tip positions, and a digital camera is also present.

• <4 K – 400 K temperature range with liquid helium
• 77 K – 400 K temperature range with liquid nitrogen
• 2 in. test area
• 2.75 in. clear view top window
• 4 micro-manipulated probe arms
• Thermally anchored triaxial single tip probe holders with replaceable tungsten tips
• 1 µm sensitivity precision actuators
• High stability spring-loaded linear motion stages
• All stainless steel vacuum enclosure for low vacuum and fast pumping times
• 7:1 zoom microscope with ring light
• Super soft copper braids transmit maximum cooling power and minimal vibrations to cold stage
• Elastomeric isolators on table for high frequency vibration dampening
• Soft air mount feet for high shock and low frequency vibration dampening
• Heated radiation shield for faster sample change
