Kees de Jager gave an update on the schedule for Hall A:
- There will be no
decision on next year's schedule until January 15, and the schedule will
depend in part on G0's review
- The tentative
schedule is as follows:
- If G0 is not ready, then there
will only be a one month down in March 2002. The septum
magnets
will then
have two months for commissioning
Paul Brindza reported on the septum status:
- A platform
was designed for the septum magnets and all present Hall A targets
- A installation
platform was also designed to add in the installation of the septum magnets
- Gordon Cates
had asked if a vibration reducing mechanism could be imployed to reduce
vibrations for the water signal. One idea was to use shock mounted
legs to surpress
vibrations. Paul had suggested that we determine where the
source of vibration is
- A brief review of the status of the septum magnets is as follows:
- The location of the sieve slits
was discussed:
* One option
is to attach the sieve slits to the septum magents
* Another
possibility is to use a similar design that the Hypernuclear experiment
will use
Steven Lassiter reported on his simulations for the field clamps:
- For a postscript file of his simulations,

- With 1" field clamps, the field
due to the spetum magnets is reduced
by a factor
of 10 at the target location
- Steven also said that by running
both magnets, they cancel each other out at
the target
- He was asked to do a complete simulation
including the field from the
helmholtz
coils to see how the field clamps affect the uniformity of
the helmholtz
coils
Doug Higinbotham reported on the septum optics commissioning:
- For the initial commissioning, the
vacuum will be broken to put
the sieve
slit in and out
- The new root analyzer will be used
for the optics
- The present optics database is wrong.
John LeRose is working on a
data base
that will incorporate the septum magnets
- Doug, Nilanga, John LeRose, and
Ken will formulate a plan and details for
the comissinoning
before January 15
