basic upgrades and maintenance (Giles, Hua-Bai)

• add camera to view tertiary (see separate folder; see also "computers") (ORGANIZE THIS FROM POLE)
  • see separate folder with info
  • buy camera plus spares in US
  • Matt (or Greg?) can integrate into our system at S. Pole
  • we can use video and heater cables intended for focus motor
• maintenance on cryostat and associated systems
  • replace red-handled valve with cold-tested valve (DONE - TEST AT POLE)
  • develop plan for on-telescope warming to 100 K (DO AT POLE)
    • need insulated pump-box at plank, probably in box and with minimal instrumentation
    • think through what is involved in a very long fill (few hrs.) during winter
