TOF Procurements

gluing jig, materials arriving

procurements, moving forward specifications to eljen and stgobain, heard back from eljen AJ200 revamped machines, can get scintillator sooner than anticipated, within 6 weeks of order flook of orders to both firms for scintillator, japanese reactor crisis-related chuck halbert

uvt acrylics, addtional quotes requested, another company can provide same material, came in better 240 ft can be delivered in 6 weeks purchased 2 rods from new company 3m, esr daylighting film trying for long rolls, rather than small sheets

TOF Construction

construction jigs, increased spacing glue 9 scintillators at a time ian working on a wrapping jig u- channel, with wrapping material coming up and wrap material around rtv for mounting pmt's spin-off of ge sillicon, momentum produces rtv 615 and 655, 615 used at other experiments,

tests done with glue, done on a verticall surface, looks good 20 ft-lb torque, no budge
