- Ricor 1-Watt Sterling Cycle cryocooler & metal adsorber for cryosorption pumping w/temperature monitoring
Space Ice (SPICE) Chamber
- Chamber identical to that used by Cassini INMS in Lab 355
- 16” x 16” cubic cylinder
- System pumping: 1 Cryo-Torr 10’s (3000l/s pumping speed), Dry scroll pump and 70 l/s turbo pump
- Numerous available flanges at an assortment of chamber positions for electrical feedthroughs.
- High purity nitrogen available for instrument purging
- All chamber venting done with high purity nitrogen

Space Ice chamber environment diagnostics/monitoring include:
- Positioning system for manipulating sample
- Manual temperature control to cryogenic levels using in-house fabricated cryostat
- Pressure control
- PC controlled through Granville-Phillips Stabil-Ion® gauge & controller
- Routine base pressures of <1 x 10-7 Torr at ambient temperature, < 1×10-8 Torr when cold
- Reaches cross-over point in < 30 minutes
