Tagger design

[Tim Whitlatch <whitey@jlab.org>]

Hello all,

 As we had discussed during yesterdays meeting, I have posted some 
drawings showing the critical dimensions and interfaces for the magnet, 
hodoscope, microscope and vacuum chamber. I know some of these do not 
match what is currently being used in the software. I took a stab at the 
magnet dimensions with the increased step in the poles for the vacuum 
chamber walls. I have posted the drawings in order to get feedback and 
consensus on the required numbers. Please review them and add return 
comments to the email list. In order to have a reasonable set of 
consistent drawings for the Tagger review, these need to be nailed down 
within a week.  If I missed anything or misrepresented anything, please 
let me know. The drawings are on the wiki at;

The last 2 links under the Tagging spectrometer with the Sept. 26, 2008 
date.

Cheers,

       Tim
