[Halld-pid] [EXTERNAL] TOF shielding

[Paul Eugenio]

Dear Tim,

Beni pointed out the broken module today.   I am alarmed that this happened.  While adjusting the brackets in the central region is challenging, there should be NO force placed on the module PMT ends.    I want to really stress this point.   If we have a problem with the mounting then we should better design the central brackets.  I’m thinking that we should replace the double bracket with a new design going back to a single bracket adjustment.  This could likely be done with a redesigned collar which has a central tab for bracket connection.  This way we could use a much narrower brackets.


Paul
