18 Sextupole Magnet Coils manufacturing 18

19 Steerer Magnet Coils manufacturing 19

20 Epoxy resin for coils -the transparent and radiation resistant epoxy resin - MY745, was purchased from Huntsman; - for coils potting, there were tested several types of molds made from silicon, but the tests leads to the conclusion that we need to manufacture metallic molds, because the resin attacked the silicon; - the tests were performed by Bertuel Prototypes - France; - the molds were manufactured, also by Bertuel. 20

28 Yokes manufacturing We have created a sextupole magnet stack of lamination: stacking > gluing > outer milling > stainless steel plates welding, with very good results; also for the steerer magnet. We have tested the EDM process, for the sextupole yoke and also, for the steerer yoke, but the measurements revealed that some dimensions are out of the imposed tolerances. 28
