# Agenda for 10/30/03 Femtosecond Thursday meeting at 1:00 pm in 6-1105

Phil\-\-\-\-- Beamlines update, grating specifications

Steve\-\-\--Insertions update. W11 fabrication. IVID procurement

Alan\-\-\--Budget overview.

**Minutes.**

Phil gave an update on the Beamlines. He said that Zeiss had informed
him that they could not holographically produce the 150 l/mm. grating
due to a minimum angle constraint between the beams. As a result Phil
has changed the baseline design from 150 and 600 l/mm. to 250 and 1000
l/mm. He has re-optimized the spectrometer monochromator for the soft
Xray beamline. Changes are required in the angle and length of the
pre-mirrors,as well as the beam offset which goes from 20 to 27 mm. No
changes are needed between the slits, M12, the grating, M13 mirrors and
the detector. Phil showed curves to compare the new efficiency with the
original design, these indicated a reduction of about 20% and a much
steeper falloff above 1500eV. The resolution of the new design is
similar to that of the old one. The status of the optics is that the
grating specification has now been written and a drawing is expected
from Nord by Monday, the package can then go to Purchasing. For M101 and
M201 Phil has started the specification, Daniela is working on the
mechanical design. The schedule for this procurement had been to place
the order in October.

Steve gave an update on the Insertions. The W11 should be moved into
Building6 on November 18^th^., the assembly continues on schedule. Next
week the plan is to put the magnetic measurements system together. The
machining of the fourth vacuum vessel half has started at Allied
Engineering. Regular visits are being made to Allied to track progress
and help assure the machining of an acceptable part. Guy Pulsifer of the
Mechanical Shops has made three visits. Steve reported that some chatter
was observed to be starting but thought that this was being remedied by
the implementation of Guy's suggestions. The initial resistance to
suggestions seems to have diminished as Guy has been able to communicate
with more appropriate personnel at Allied. Steve continues to work on
the specification for the IVID and has met with Alan Biocca to get his
input on the controls requirements. He will meet with Christoph next
week on physics related issues and then he has a scheduled meeting with
Sue Walker-Lam who has assumed the responsibilities previously held by
Ron Ball in Purchasing. A Procurement Advanced Alert has been filed and
a draft of the Sole Source has been prepared for discussion. The draft
MOU between LBNL and Spring8 has been reviewed and modified by the
Laboratory lawyers without any substantive change in the content. This
will be sent to Spring8 to get their input before a final version can be
drawn up. Sumitomo are working on an updated budgetary quote for the
IVID based on our latest guidance. They are to assume that the narrow
pole is acceptable and that we require a 5.5mm minimum gap , with a 1.4
Tesla minimum field, and with a goal of 1.5 Tesla. The group agreed that
the final Sumitomo design will be verified for acceptability using
simulations. Steve was questioned as to why the potential quote from
Sumitomo is feared to be much higher that our original guidance.
Sumitomo had given us a \$600K number which Steve believes was based on
the device fabricated for the SLS. A \$700K number was included in our
draft cost estimate. Since then there have been required design changes,
the Dollar has significantly weakened against the Yen, and a competitor,
Dan Physic (SP), has produced a device at a much higher cost.

Alan presented the budget performance on the fabrication of the W11. The
costs plus Leins to date are as originally anticipated in the project
spending plan, this includes the \$30K to re-assemble the magnetic
assemblies. A cost to complete has been estimated and we expect to
complete installation on budget. Dave has now estimated the cost of
completing the Hard Xray Beamline, at this time these figures are
preliminary and have not been reviewed. Making several simplifying
assumptions, Alan had attempted to fold these figures into the overall
budget yearly spreadsheet. Rob pointed out that Dave had included the
cost of the front end in the beamline and that Alan had failed to
account for this adjustment. The spreadsheet had been prepared in haste
immediately before the meeting and its presentation to the group was
premature. The costs estimated by Dave are considerably higher than the
figures that Tony had presented in our comparison between the options of
a combined function beamline and separate function beamlines. Rob had
been earlier advised of this and had contacted Tony to get a review of
the figures. Alan requested that Dave , Rob, and Tony, get together to
review the estimates and identify the specific reasons why they are so
different.

**Action Items (Updated)**

Dave, Rob, Tony\-\-\--reconcile the latest beamlines cost estimate with
the earlier estimate produced by Tony

Phil\-\--schedule Chopper design review with vendor.

Alan\-\--Discuss with Jim K. the sharing of costs with Sumitomo for the
magnetic assemblies.

David\-\--establish the shielding requirements for Top Off operation
with Rick Donahue

Alan/Bob\-\-\--reconcile ALS funding plan with the requirements of the
scope and schedule.

Steve \-\-\-\-\-\-\-- find out the specifics of what is driving the cost
of the IVID, and what design parameters can be negotiated to reduce the
cost.

Christoph\-\-\--Conclude longitudinal field harmonics study by end of
September.

Dave P.\-\--work with Tony Catalano to develop the beamlines schedule
consistent with engineering manpower availability, yearly funding
requirements, and to document scope.

All -- risk mitigation plans

Christoph/Ross/Steve\-\--resolve ID field and roll-off issues

Steve\-\--Collect data from the three existing designs for the power on
the RF shield for the IVID.

All\-\-\-\-\--update review presentation book.

Check options for W16 cost recovery with Gavin Robillard\-\-\--Alan

(Steve reports from Robillard that if another national lab expresses
interest in W16, we can only expect them to pay incidental costs of
removal from the ring, packing, shipping etc.)
