Beamline safety notes by Lew Keller, Elton, and I concerning beamand tagger (fwd)

[Jim Stewart <jstewart@jlab.org>]

Dear tagger

Elliot points out that the design of the beamline downstream of the tagger
magnet will be affected by any devices needed for radiation protection.
Essentially if the tagger magnet trips off you need to shut off the beam
to the hall fast. This requires several redundant measuring system.

In the below mentioned notes the beamline varies from 15cm to 60cm in
diameter.

Hi Jim,

I found the notes on the tagger and beamline safety by Lew Keller et al:  check out GlueX
docs 32, 33, and 599.
