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