Updated Run Plans. • - pre-commissioning- Target, • - beamline functionality • detectors, particle production • decay solenoid • - steps towards (6π,200) muon beamline K.Tilley, MICO, 07/02/08
pre-commissioning : -Beam monitor backgrounds/calib/DAQ -completion of p/s services -DSA entry:- completion of mgt services - polarity(power) from p/s - direct klixon checks(B2,QN) - (klixon) interlock checks - system soak tests – stability/thermal - Synch entry:- polarity(power) from p/s - direct klixon checks (B1 esp, Q1/2/3) - (klixon) interlock checks - system soak tests – esp B1. (1/2hrs) - field at saturation – B1.
Target : - negotiate agreement to activate target.Formal plan. To include:- position reproducibility (shallow dip) flux / beam loss signal reproducibility. Reliability insert towards 38mm &/or 0.05V. Loss v dip. Crude production estimates (using upstream monitor) pre/post activation measurements. Radiation levels in MICE hall. (Tgt only)
Beamline functionality – to exercise beamline slow controls beamline model understanding beamline monitors - poss can overlap with Target work. - poss can overlap with det/DAQ cmsg/p.prodn. - 500MeV/c protons, since best rates - likely reasonable pion flux, albeit <10%. - what will do:-….. Exercise Quads, Diploles, confirm optics. Probe & set alignment MICE Hall radiation levels. - have proton optics (Q1,Q2. triplet in devmt) - Require…triplet lattice, scenarios, alignment simulations & procedure- desire… settings store/restore, B->I programming
Detector calibration – to commission available detectors [Ckov etc] - to shakedown DAQ / MLCR.& particle production [Ckov can disting π+ if run +s] - require to sign off rqd beamlines [difft dE @ each E: air, mtrls etc] & then produce:-example stages:- positive pions [?]: • [ incl protons or high purity pions desired? Thus include proton abs]- Can provide up to ~500MeV/c, quads on. [imperfect but ok workable above 400] • Number of scan points? • negative pions:- • Can provide up to ~500MeV/c, quads on. [imperfect but ok workable above 400]- Number of scan points? • electrons:- - Require new optic @ ~100MeV/c, quads on.
Decay solenoid commissioning - hardware commissioning: cooling. Power. Interlocks. Quench checks etc. Field polarity measurements etc - with beam commissioning:- (using detector on DS end) [beam dynamics from ABl note]
Steps toward 6π muon beamline in Step I Require:- assume all detectors incl TOFs, Tracker available - reconstruction available. pions through whole system @ ~ 280MeV/c: - optimise u/str optics for flux, alignment, spot size DS d/s - d/str beamline with pions ~ 260MeV/c for alignment optics? Scale upstream to ~ 444.7MeV/c - final check of upstream optics. Downstream @ 260MeV/c @ backward decay muons: - backward decay should be aligned. - measure transmission, natural emittance. - calculate rqd matching parameters. - optimise for (6π,200) with optimiser scheme.
