A cryogenic monitor system for the liquid argon calorimeter in the SLD detector
M.J. Fox, J. Fox · IEEE Transactions on Nuclear Science · 1989
The authors describe the monitoring electronics system design for the liquid argon calorimeter (LAC) portion of the SLD (Stanford Linear Collider Large Detector). This system measures temperatures and liquid levels inside the LAC cryostat and transfers the results over a fiber-optic serial link to an external monitoring computer. System requirements, unique design constraints, and detailed analog, digital, and software designs are presented. Fault tolerance and the requirement for a single design to work in several different operating environments are discussed.>
