Mustang Spares List

Draft version 16jul07

Note the definitive reference is the spreadsheet attached at the end of this page ... the notes on the wiki were just to get things started.

These are all the spares we'd like to have. Those coded green we know we have. Those coded yellow we think we have, but their status needs to be checked. Red, we don't have. When in doubt I color things in the alarmist fashion.

• PT407 -- 3/4 watt version is about $24,475 ($38,795 including compressor and hoses; $18,450 for just the air-cooled compressor). Note that Penn's ran for 12,000 hours before failing and needing a rebuild, which costs $2,000 or so and was turned around in under 6 weeks.
• PT driver & rfi box for it.
• New test dewar
• Spare He7 system
• DFBs -- N x $2,000. What is the appropriate value for N? Should we have a whole crate's worth of spares in case the crate itself gets fried? Currently we have 2 known good DFB, and perhaps One More DFB which needs checking.
• Interface card -- the one we have at GB is a prototype, and not suitable as a hot spare.
• Clock Card
• NIST POWER CONDITIONING CARD
• cold address driver
• Tower cards
  • bias (complete system has 4? we have??)
  • preamp (complete system has 1, we have none)
  • address card - need programing
  • spare address card prom
• pressure gauges for GB cryogenics ops
• manifolds for GB cryo ops
• Flex Lines -- $2K.
• Tekdata cables -- Need several repairs - parts are on order (13/3/2008)
• Vicor power supply -- This should be rebuilt in summer 2008
• GPIB -> Fiber converter
• Series Array
• Cold head driver

• ARRAY

GB FY07 year end purchasing

Items we will get from the above, if possible, and other year end purchases for the project.

• PT407 + driver ($25K)
• 64-bit data analysis machine ($6K)
• tekdata cable repair/replacements (a few K)
• the rest DFB cards probably at ~$2K/ea
