1. Paul Barclay p.j.barclay@rl.ac.uk SCT COOLING PRR 14-4-5 DESIGN PERAMETERS a)ACTIVE LENGTH TO MATCH Q.M.U.L PROTOTYPE b)GENERAL LAYOUT OF HEAT EXCHANGERS IN TRAYS BASED ON DRAWING TB-0049-741 AT RAL c)44 HEAT EXCHANGERS REQUIRED COMPRISING OF A POSSIBLE 11 VARIATIONS IN TOTAL FROM THE FIRST ASSEMBLY TD-1056-501 d)DETAILS OF TRAY LAYOUT IN CRYOSTAT TAKEN FROM Pro-e MODEL TD-1056-003 AT RAL. TRAY ALL FITTED TO CRYOSTAT e)COMBINED CONNECTORS AND ELECTRICAL ISOLATORS (GROUNDING) DEVELOPED AT RAL TO SATIFY SPACE/THROUGH DIA AND MASS RESTRICTIONS. NO COMMERCIAL EQUIVALENT. f)FILTER- TO SCREEN OUT OBJECTS LARGE ENOUGH TO COMPROMISE THE INNER DIAMETER OF THE CAPILLARIES. REQUIRES MINIMAL FLOW RESISTANCE AND TRAY SPACE. NO CONECTIONS g)ASSEMBLY ---Q.M.U.LONDON…..TOOLING BY RAL & Q.M.U.L h)CLEAN—Q.M.U.L i)TEST - Q.M.U.L & CERN
