MINUTES

Bob reported on the meeting with Pedro Montano. In order to bypass the
requirement for a CD0 and CD1 it is planned to keep the project budget
below the \$5.0 M level for the DOE project funding. (The s/c undulator,
wiggler and front end will be funded by the ALS and LBNL) These
requirements would delay the project start and it is considered very
critical to complete the project in 2005. A tentative funding of \$4.8
was indicated. Possible reductions in scope may be required to meet this
some \$0.5M funding shortfall over the proposal request. A reduction in
the laser system frequency from 40kHz to 20kHz could be an option.

Kem Robinson has not yet published his list of topics to be covered in
reviews. November 18th. has been selected as the date for the review of
the W11 and we are targeting the week before Christmas for a one and one
half day review of the rest of the project.

Christoph described the problems that had been experienced at SPEAR with
their wiggler. They had been unable to inject with the wiggler gap
closed, and lost beam if the the wiggler was closed during operation.
The problem was traced to an inadequate specification for the field roll
off . Because the electrons \"wiggle\" as they pass through the device
they are subject to a strong kick as a result, this is not what is
predicted if a straight path through the device is assumed. The
requirements for our project should be less stringent than SPEAR but we
need to verify that our design will be acceptable.

Weishi described preliminary results of simulations aimed at resolving
the field roll off issue so we can set the specifications for our W11.
Work will continue in this area.

Steve presented the first draft of a plan and schedule for the
superconducting undulator. This plan was based on our successful
superbend project. Building on the experience gained in the LDRD in AFRD
the first year calls for prototype building and testing. This would be
followed by design of the undulator followed by industrial fabrication
with delivery of an assembly early in 2005. Extensive testing and
verification of the device would then take place with installation
planned for the fall. It was pointed out that any ALS shutdown should
not occur in the summer as this is prime operational time for the ALS
user community. The procurement funding requirements are presently
estimated at some \$1.1M with an LBNL engineering effort of
approximately 3 FTE for each of the three years of the project.

The importance of finding out exactly what is happening in Europe with
Accel, ESRF etc was discussed in the hallway after the meeting
concluded. It was suggested that if possible we should invite Accel to
present their current status and capabilities to us.

ACTION ITEMS

\(1\) determine the status of other sc undulator projects - particularly
at

ACCEL, see if they would be interested to bid on our device, or if a

collaboration with another facility would be worthwhile\--Ross/Steve

\(2\) establish criteria for evaluating field roll-off specs for wiggler
and

undulator-Christoph

\(3\) get list of Robinson Review requirements and set date for full
project

review\--Bob/Alan

\(4\) check status of budget and start date with DOE-Bob
