FormFactor - HPD Model HE-3-TLSUHV-STM - Wet Helium-3 Cryostat
-
Long holding time: 80 hours with 10 STP liter He-3 gas
-
Stable He-3 pot temperature: Separate sippers for 1K pot and the charcoal sorb cooling line
-
Sample can be loaded or removed when the cryostat is cold
-
Low noise, low vibration
-
Multiple operation modes: He-3 cryostat can be operated without pumping the 1K pot (referred to as 4K operation mode)
The Model HE-3-TLSLUHV-STM is a top-loading Helium-3 cryostat with sample in ultra-high vacuum (UHV) space for scanning tunneling microscopy (STM) with atomic resolutions. The sample can be loaded through the 1.0” diameter central access when the cryostat is cold. With its standardized unique design, this He-3 cryostat generates next to zero acoustic noise and mechanical vibration. The Model HE-3-TLSUHV-STM He-3 insert is designed to be compatible with all kinds of superconducting magnets, such as solenoid, vector magnets, and more.
This He-3 insert includes the following components:
- Central access with gate valve on top
- Charcoal sorption pump with heater and thermometer
- 1 K pot with heater and thermometer
- He-3 pot with heater and thermometer
- Permanently stored He-3 gas
- UHV compatible IVC can
- Mechanical heat switches
- Operation test

-
Ease of use – Less experienced operators can perform an RF calibration up to 500 GHz by simply pushing a button. This reduces the need of experienced users full time on each system.
-
Reduced Soak Time – The system will automatically re-align the probes to the pads if they drift from alignment. This reduces test time and increases throughput.
-
Unattended Use – Measurements can be left running over night or the weekend, testing all devices on the wafer, and at different temperatures without the need of an operator.
-
Calibration Monitor and Re-calibration – System will
continuously monitor calibration drift, and automatically re-calibrate the system should the drift exceed a predefined limit.
