Presentation Transcript
Dear all, during our last meeting on Nov. 18th we defined the beam parameters to be recorded using which machines (last two slides of attachment). Additionally, we agreed on follow-up activities. I hereby cordially invite to the next meeting to present the results / status of these activities. These activities are listed below together with the respective person in charge: - confirm or re-define the number of shifts needed for individual machine tuning: o UNILAC: 6 (Hartmut) o SIS18: 4 (Jens) o ESR: 4 (Markus) o FRS: 4 (Emma) - we agreed already that a total of six shifts shall be foreseen to consistently record the defined parameters after individual machine tuning - definition of time slot for the campaign (Stephan) We also agreed that the subsequent persons shall define the detailed shift planning (program, persons), depts. needed on call, data logging procedure, and equipment preparation: Ralph, Winfried, Peter Sp., Markus St., and Emma. Hence, I kindly ask the machine coordinators to present their needs w.r.t. amount of shifts and the dept. heads to present their individual progress of planning during that meeting. Participants to meeting on 03.03.2020: Query of achieved beam parameters 1
Motivation GSI shall report the status on what has been really achieved at existing facilities w.r.t. beam parameters essential content of measured-parameters list: what parameter, where, when parameter, nomenclature of device, date & time prefered: data that was stored in and is retrievable from log files (transmissions, emittances, profiles, ...), i.e., location- and time-stamped data files available from CS Beam parameter campaign 2020 2
Data collection AccOp head asked LG to inquire these data from the MKs Template table has been agreed and sent out Query is initially restricted to data related to uranium FAIR reference, i.e., : source: 238U4+ post-stripper: 28+ SIS18: 28+ ESR: whatever Beam parameter campaign 2020 3
Available data: UNILAC U4/28/28+ C: post-stripper exit I = 5.1 emA x/y = 0.15/0.21 m Bx/y = 35/25 emA/ m July 21st, 2016 A: LEBT exit I = 11 emA x/y = 0.088/0.077 m Bx/y = 120/140 emA/ m July 21st, 2016 1: UNILAC exit I = 4.3 emA x/y = 0.15/0.16 m Bx/y = 29/27 emA/ m July 21st, 2016 B: post-stripper entr. I = 5.4 emA x/y = 0.21/0.20 m Bx/y = 26/27 emA/ m July 21st, 2016 1 U28+ B C A U28+ U4+ U28+ Beam parameter campaign 2020 4
Available data (all GSI): (U4/28/28+) if not stated explicitly 1: UNILAC exit I = 4.3 emA x/y = 0.15/0.16 m Bx/y = 29/27 emA/ m July 21st, 2016 4: SIS (fastly extr.) N = 3.2 1010 x/y = ... m Bx/y = ... emA/ m 2012 2 3 4 2: SIS (injected) N = ... x/y = ... m Bx/y = ... emA/ m XX yyst, zzzz 5: ESR (stored) N = 1 108 (U92+) x/y = 0.1/0.1 m Bx/y = 1/1 109 part/ m March 29th, 2000 6 1 5 3: SIS (flat top) N = 4.3 1010 x/y = ... m Bx/y = ... emA/ m 2012 6: FRS (target) N 1.5 109 x/y = ... m Bx/y = ... emA/ m routine of recent years Beam parameter campaign 2020 5
GSI overall data is sparse and not consistent data beyond UNILAC is partially outdated, not stored, incomplete, not consistent in order to achieve a presentable set of consistent data, being retrievable from logs, a dedicated campaign is invisaged this campaign shall be conducted end of physics run 2020 purpose of todays meeting is to define . next page Beam parameter campaign 2020 6
Beam parameter campaign 2020 which machines: North, UNILAC, SIS18, ESR, FRS what ion: uranium UNILAC: SIS18: ESR: FRS: 4/28+ (73 +set-up), 11.4 MeV/u 28+ (73+ (set-up), 200/1000 MeV/u(73+) 92+ 73+ parameters to be measured and stored (!!) UNILAC: current, emitt., energies, profiles, pick-ups @ UH1, US4, UA4, TK5 SIS18: intensity, profiles, Schottky, life time, emitt. at inj/f_extr flat top, 10 T/s ESR: intensity, profiles, Schottky, life time, emitt. at inj/extr flat top FRS: intensity, spot size, emitt. (transv. & long.) Beam parameter campaign 2020 7
Beam parameter campaign 2020 number of shifts for single machine preparation (to be confirmed by pers. in charge): UNILAC: 6 SIS18: 4 ESR: 4 FRS: 4 number of common shifts to do consistent parameter determination: 6 time slot: head of OPE persons in charge of prep. & execution: heads of IQ, LAC, SIS18, ESR, FRS shift personnel, Depts needed in RU, readiness of eqippment, logging, . coordination of these persons: head of PSU consolidation & presentation of results:head of PSU Beam parameter campaign 2020 8
