Hi Zisis,

Sorry, I initially only looked at your abstract and not at the entire 
executive summary.

 From the summary, I have a more fundamental question regarding the 
orientation of the module relative to the tagger/electron beam.  First 
we are confused as to why the footprint along the beam is so large. You 
mention that the angle adjustment is 0-50 deg. We assume that 0 deg 
corresponds to the module positioned perpendicular to the electron 
plane, but some of the description does not match this assumption.  It 
may be useful to send a sketch with some dimensions and angles indicate, 
or you can call my office and we can work though the questions.

Thanks, Elton.
