CERN Short (2 m) Model Program Assemble and test the RRP-54/61 coil (reacted) as single coil assembly (MBHSS101) using existing collars, yoke, welded outer shell, and end plates Two RRP-108/127 coils to assemble and test the 1st 1-in-1 model (MBHSP101) Two RRP-132/169 coils to assemble and test the 2nd 1-in-1 model (MBHSP102) Collared coils from MBHSP101 & 102 to assemble and test the 1st 2-in-1 model (MBHDP101) Idem for PIT-cable: 2 x 1-in-1 model (MBHSP103-4) to have tested collared coils for the 2nd 2-in-1 model (MBHDP102). Will be conflicting with MQXF and other magnet projects in terms of human resources and infrastructure 12 June 2013 M. Karppinen CERN TE-MSC

CERN Prototype (5.5 m) Schedule Start with winding trials using Cu-cable: simplified trials coil with bare cable first practice coil with insulated Cu-cable to react and pot (PC-1). First Nb3Sn practice coil with possibly low-performance (cheaper) cable (PC-2) First “real” coil (PC-3) to cold test as a single coil (mirror?) Four (or eventually more..) more coils for 2 collared coils to construct the full-scale proto and test it in Mid-2016. the 5.5 m schedule is compatible with the present LMF plans including the major procurements Additional coil production lines will be required for series magnets It is also vital to get the industry on board during the prototype construction to be ready for the series units 12 June 2013 M.
