EE cooling status Justin Greenhalgh
Cooling areas of interest • Global heat flows • Cooling pipe runs inside ECAL • Local heat flow in electronics (max T?) • Efficacy of crystal cooling • Heat flow down umbilical • Heat flow at front
Global heat flows • Paper written • Reviewed by RP et al, broad agreement • Outstanding areas now being considered
Cooling pipe runs inside ECAL • Work now in hand jointly between RAL (LGD) and CERN (RP et al) groups • System-level diagrams (CERN) • Pipe runs (RAL -->> CERN)
Local heat flow in electronics • Experimental program in progress • See Tony’s talk for more • Useful input from Werner Lustermann et al.
Efficacy of crystal cooling • Heat flow down umbilical • Heat flow at front end • Experimental program being put in place
