Obsolete Pages

Most of these pages deal with the Virtex-4 FX12 revision of the cryoelectronics board. While they are still relevant, they should be treated with a little care to ensure they are not obsolete.

(GMS, Aug. 2010: I just moved all of these pages into an "obsolete" header pending public release of the Spartan-6 cryoelectronics board. I will bring them back out when I'm ready to vet and update them.)

• FinalReport Pete Dahlberg's Final report from physics 479 summarizing work done on the Cryoelectronics and its current functionality as of summer 2009
• CryoElectronics - to do lists for design of electronics for cryogenic control.
  • TemperatureReadoutSystem - system description and overview by Shah
• CryoElectronicsFirmwareDesign
• CryoElectronicsFirmwareInstructions
• CryoElectronicsTesting
• MemecMiniModuleModification
• CryoCgiScripts - an outline of the cgi scripts that will be needed for the Cryoboard webpage
• ResistorSelectionForCryoBoard - a guide to choosing the correct resistor for a given sensor (under construction)
• CryoAnalogGains - an analysis of the drive and sense channel gains for the cryoelectronics board
• PythonFridgeCycle

Quirks Pages

These pages document hiccoughs or other miscellany in the software, firmware, or hardware that will hopefully be addressed by improvements in future revisions.
