EMMA Commissioning

EMMA (Elec­tron Ma­chine with Many Ap­pli­ca­tions) is a pro­to­type non-scal­ing elec­tron FFAG to be host­ed at Dares­bury Lab­o­ra­to­ry. NS-FFAGs re­lat­ed to EMMA have an un­prece­dent­ed po­ten­tial for med­i­cal ac­cel­er­a­tors for car­bon and pro­ton hadron ther­a­py. It also rep­re­sents a pos­si­ble ac­tive el­e­ment for an ADSR (Ac­cel­er­a­tor Driv­en Sub-crit­i­cal Re­ac­tor). This paper sum­maris­es the com­mis­sion­ing plans for this ma­chine to­geth­er with the major steps and ex­per­i­ments in­volved along the way. A de­scrip­tion of how the 10 to 20 MeV beam is achieved with­in ALICE is also given, as well as ex­trac­tion from the EMMA ring to the di­ag­nos­tics line and then dump.
