Model HE-3-TLSL

The Model HE-3-TLSL cryostat is a top-loading system with sample in (He-3) liquid for fast sample exchange. The design allows the sample to be removed from and introduced directly into the He-3 pot while the cryostat is cold. The system also includes a sample probe and a load-lock with gate valve, plus an external gas handling system for safe insertion and removal of the sample in and out of the He-3 chamber.

This He-3 cryostat includes the following components:

• Charcoal sorption pump with heater and thermometer
• 1 K pot with thermometer
• He-3 pot (sample chamber)
• Load-lock
• Sample probe with thermal anchor stage, thermometer, and heater
• IVC can
