Re: Tagger interface drawing




Tim,

thanks for producing the drawing - without the placement of the tagger
package in the hall it's really difficult to imagine the real estate.
I have 2 concerns (we can discuss that tomorrow):
a) exit beam pipe (like in Yang's and my files) has still a flange and
comparatively small pipe (2 1/2"). Let's see whether we can get an oval or
rectangular form (as proposed in the SoW);
b) in the SoW I asked for downstream extension of the vacuum chamber to
prevent backscatterer into the tagger counters.

I have to admit that I haven't touched the (preliminary) 3D model any more
for 7 months; I should have made the changes there ...

Let's talk tomorrow

Franz

ps. Can I borrow a detailed civil drawing of the collimator cave for 2-3
weeks?
