EHODO(used in previous experiment)

ADC vs TOFTOF=171[ps]1ch4ch3ch2chCut coercively ADC 1chThen, TOF =150[ps]

Cut coercivelyEHODO timing resolution(Run56)1ch3ch4ch2chIf the slewing correction could be more better, TOF sigma~=150[ps]. UV curing glueUV curing glueHas not arrived

So I tried to bond PMT and scintillator(HTOF2Y) using the glue used Hampton group.

Mission failed ..(Exp. date 20Jan2009)

summaryEHODOTiming resolution TOF sigma~=160[ps](sigma~=150[ps] )UV curing glueIt has not arrived.I cant work on assembling of EHODO & HTOF1Y.
