Paul Barclay SCT COOLING PRR DESIGN PERAMETERS a)ACTIVE LENGTH TO MATCH Q.M.U.L PROTOTYPE b)GENERAL LAYOUT OF HEAT EXCHANGERS IN TRAYS BASED ON DRAWING TB AT RAL c)44 HEAT EXCHANGERS REQUIRED COMPRISING OF A POSSIBLE 11 VARIATIONS IN TOTAL FROM THE FIRST ASSEMBLY TD d)DETAILS OF TRAY LAYOUT IN CRYOSTAT TAKEN FROM Pro-e MODEL TD 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
