got scintillators back from plastic craft three that came back were crazed 5% iso alcohol. naptha, ordered replacement paddles
werner looked at it, some candidates 1x4 or 1x5 favored with 30 paddles
look at different products from H; mantis!!!
2x4 would also work
actively explore using 4x4 as is
explore opening up diameter of sc array
look in catalog
werner back next week
simple light guide design better
two mistakes: ignored recommendation, iso, naphta, petroleum extract damaged three one that came back was better than before
other mistake: sequescen bend machine, polish machine and polish and then bend better
ordered replacement from elgen
if choice: hard to find replacement for plastic craft,
made a demand that they consult better
will try to test some
overlap between rohacell
need to make target geometry consistent
need a tagged release
action item, update drawings
are flat sides polished? usually come smooth from manufacturer
one concern: puneet, straight portion,
this simulation 24 paddles
working on rate and radiation dose using geant4
