If the slewing correction could be more better, TOF sigma~=150[ps].
UV curing glue
UV curing glueHas not arrived…
So I tried to bond PMT and scintillator(HTOF2Y) using the glue used Hampton group.
Mission failed ..(Exp. date 20Jan2009)
summary
EHODOTiming resolution TOF sigma~=160[ps](sigma~=150[ps] )
UV curing glueIt has not arrived.I can’t work on assembling of EHODO & HTOF1Y.
To do・ EDC・ Check assembled EHODO’s PMTs・ Taking data of EHODO, WC
