SPARO Design Issues
Below is a rough list of design
decisions and possibilities. (As of 12/18/95.)
- To be specified:
- reservoir size
- dewar size
- location of He3 pumps
- size of He3 system
- number of He3 systems
- Innovations we might implement:
- vapor cooled shield
- pumped pot
- He4/He3 liquid diode (for He3 pot heat switch)
- weak thermal link "heat switch" to He3 pump
- Kevlar supports (rather than G10)
- Kevlar pulleys (instead of G10 shafts)
- short signal cables to Jfets
- SPARO properties already specified
- Two 9 detector arrays
- Indium O-ring seals
- size of optics
