Starting Point

• A simple Continuous Flow (CF) system

http://www.iceoxford.com/images/products/4k-wet-02-new.jpg


• A more complex CF system

• Designed in collaboration with RAL

• Low helium use

• Low Base temperature

• High Levels of temperature stability



Variable Temperature cryostats

• Low temperature (1.2K)

• Long hold times (low helium boil off)

• Designs easily modified to suit customer requirements



Variable Temperature cryostats

• Low temperature (1.2K)

• Long hold times (low helium boil off)

• Designs easily modified to suit customer requirements

• Full magnet range, split pair and solenoid.

• Windows, choice of materials.



DRY 4K system

• Fast sample change

• Fast sample cooling

• Vibration isolation

• Mylar windows (in this case)



DRY Variable Temperature CryostatsLemon Cryostat

• Designed in collaboration with customer NIST

• Large top loading sample space

• Fast system cool-down

• Fast sample turn around

• Circulating system runs continuously no external cold traps



DRY 3He CryostatsLemon System

• Both Top and Bottom loading designs

• Uses comparatively small amounts of 3He gas• Less than 270mK base temperatures• Long hold time, more than 60hrs

• Temp. Control up to 300K

• Fast sample exchange on top loading system



Dilution Refrigerator systems

• Can be designed to suit our competitors cryostats In this case Orange.

• Automatic touch screen gas handling



Dilution refrigerator in DRY variable temperature cryostat

Lemon System

• Lower Base temperature than the equivalent orange cryostat

• Fully automated Dilution and cryostat
