MIP response for CuCu200, UxV method

  • Data from:
    * ramp-run 6049127, 735K eve, no trig selection. E:B=3:1
    * minB-run 6049129, 107K eve,
  • calib: - actual peds, no masking, SMD gains from slopes: gain=-500/slope.
  • MIP search params: thrMipSmdE/MeV=0.30 emptyStripCount=6 twMipRelEne/high=0.50/1.50 offCenter=0.80
  • expected MIP position: towerMipE[i]= 1./(2.89*TanH(etaValue)); // GeV EM

    Example of spectra for tower 05TD02 (tw/pres1,pres2,post) (PS)
    X=axis ADC-ped. Raw spectra are in black: solid=ramp, dashed=minB. MIP tagged spectra: blue rampTrig, red =minBtrig.
    Vertical lines: red-dashed - predicted MIP position. Green lines [0.5,1.5]*MIP
    Note, EHT6 threshold is barley visible in tower raw sepctrum at ADC of ~85.

    Mip tagged spectra for 12 towers in subsector 05TA
    X-axis -10,60. Spectra: blue rampTrig divided by 7, magenta =minBtrig. Vertical lines: red-dashed - predicted MIP position. Green lines [0.5,1.5]*MIP

    Frequency plots for 'best MIP' i.e. UxV & tower energy [0.5,1.5]*MIP and pre1,2,post> threshold and XY of mip within tower limits of 0.8
    Top U-strips, middle V-strips, bottom X-Y plots

    Low count in 05TE03 is due to wrong ped for pres2 (cr87/ch71). This channels has problems (ped at 5 ADC !) as seen on page 54 of P-plot.
