[Halld-tagger] Microscope coverage

Hi,

One thing we have to discuss regarding the final
microscope location. We've already started discussing
this long time ago.

To cover the photon energy range between 8.3 GeV and
9.1 GeV we will need about 78 columns of microscope
counters. The energy range per counter is ~ 10 MeV.

The microscope consists of 100 columns so that it should
cover about 200 MeV larger range. I think that we should
'distribute'  this 200 MeV equaly for both low- and
high- energies, i.e., to cover the range
8.2 GeV < E_gamma <  9.2 GeV.

Any suggestions ?


Thanks,
        Alex
