1 1June 1 st 2009MICE CM24 - RAL1 MICE Beamline m. apollonio

2 2June 1 st 2009MICE CM24 - RAL2 - Beamline parallel session: - understand the readiness of the beamline - state of magnets with emphasis on DK solenoid - state of new target - diffuser - optics - knowledge of the beamline - emittance - rate (Lumi monitors?) - FermiLab monitors (location)? - state of other detectors: TOFs/GVAs? - discussion

Needs to be reconnected/testd VERY TIGHT SCHEDULE!!!!!!!! DK SolTested at ½ max current (5T) for short period. Need a long test at MAX current w. quench protection system when is it due? A complete test of the device is needed before commissioning. Should be OK by Sept 09, unless problem arise with long run test B2 Q4Plumbing Q5To be Q6Finished Q7By Q8??/??/09 Q9 4June 1 st 2009MICE CM24 - RAL4 table to be updated during the session …

5 5 BeamLines Availability April, 22 2009UKNF09 - Lancaster Reference Beam Line – muon (e,P=207 MeV/c) Beamlines for initial/calibration studies: from (a) with local momentum rescaling of the magnets [ with / without solenoid ] (infact we used the one with no DKsol for the aformentioned reasons) electron (@150 MeV/c)  used for TOF calibration pions (@ 300 MeV/c)  1st muons seen protons (@480 MeV/c)  1st estimate of primary intensity 5June 1 st 2009MICE CM24 - RAL5 NB : need to introduce calib. current/field for DKsol

10 FermiLab Monitors: confirm locations and readiness? 10June 1 st 2009MICE CM24 - RAL10 Could be useful to determine beam alignment (together with TOF0/1)

11 11June 1 st 2009MICE CM24 - RAL11 Optics: are we ready? (shutdown 17 Aug/1 Sept) 2Sept – 25 Oct (see later talk for details) - On Sept 2 nd we don’t need a beam matched to … something - We can use optics for  =6 mm rad / P=214 MeV/c [STEPII.1] - Rescale it to other momenta to cover STEPI + STEPII.0 - later (towards end of year) we need a properly matched beam for all the config. of STEPII.1 [trk-solenoid + diffuser]  matrix completion - more work needed to tune DS-BL (Q4-9) to match MICE optics - we may want to test solenoid at B+/-  B to increase  rate 3 6 10 140 200 240

13 13June 1 st 2009MICE CM24 - RAL13 Summary - Assume target is working - Assess magnet readiness - DKsol strongly wanted - 5T to cover up to high P  (MAX=240 MeV/c) - if NO DKsol  back to situation of ’08 - Optics for STEPI/STEPII.0 should be fine as it is - Ongoing work to complete STEPII.1 matrix - Need to assess detector readiness - assume TOF0,1 + GVAs + FLMons are in place and alive
