Re: Tagger interfaces

[Alexander Somov <somov@jlab.org>]

Hello Tim,

I looked on the drawing:

-The positions of a dipole magnet and
fixed array counters (the first and last counters) seem
to be correct (+- few mm).

-the exit flange (end plate) of the vacuum chamber has to
be modified a little bit; as we have discusses the plate 
should go perpendicular to the electron beam (I will check with
James). The electron beam going to the dump seems to be at the
right position from the egde of the vacuum chamber.

-the quadrupole magnet has not been moved
  (in the MC it's placed downstream the beam) (?)

Cheers,
       Sascha
