[Halld-pid] finalizing light guide drawings

[Chuck Hutton]

Paul,
It looks like reducing the length of the cylindrical section of the main 
light guide from 10 cm to 9cm long will be fine.  I am curious as to 
what you were able to do with the half paddle light guide? The length of 
this one was the real issue. Please send the updated models of the light 
guides when you can so that we can modify our layout in regards to the 
overall mounting of the TOF.

Thanks
Chuck

My understanding was that in addition to a straight 1cm rectangular addition, we were reducing the length of the cylindrical PMT end.  The cylindrical end reduction had not made it into the design.  Can you confirm what the length reduction was?  I thought it was going from 10cm to 9cm.
