For use in Plasma Physics for fielding cryogenic tagets
This cryostat was used in the D2 equation-of-state experiments on the Nova laser at LLNL, 1998-1999
Features:
- Temperature Range of 1.2K to 425K
- Main body dimensions, app. 4 inch OD x 32 inch long
- 1.00 inch Dia. quick connecting Sample Mounting block for cold finger.
- Coldfinger has a large litzwire type thermal connection to cryogen pot.
- Independent Vacuum Insulation, includes a fully vacuum jacketed tail section, all the way to the cold finger. (vacuum of cryostat is not dependent on the vacuum of the laser target chamber -or- the cold finger is external to the cryostat body)
- Vapor Cooled, Thermal Radiation Shield with Vacuum jacket penetration.
- Gold plated radiation shield is magnetically coupled to the cryostats vapor cooled thermal shield for quick release.
- Cryogen fill and vent ports and electrical connections are provided with a single Quick connection of the
- Abbess Bi-Directional transfer line ( see photo below )
- Indirect cooling by cryogen, liquid helium or nitrogen, Flow or fill mode.
- Cryogen pot has 1-2 liter capacity
- Helium Level sensor is included in the design to monitor the level within the cryostat’s cryogen pot.
- Electrical connection to the level sensor in the cryostat, is provided through the cryogenic electrical
- contacts of the Abbess Bi-directional cryogenic transfer line bayonet
- All joints and seals to be helium leak tested to 1×10-7 Std. c.c./sec
- 2 Heaters, one boost Heater about 60W, and one dual element heater disc, with both 25 and 50 ohm.
I would like a cryostat similar to this one CTC-11 »
Abbess Instruments’ Cryogenic Bayonet connection with level meter electrical contacts built in to the bayonet.
