## Agenda for 5/29/03 femtosecond Thursday meeting at 12:30 pm in 6-1105

**Rob/Phil\-\--Beamline update, Cost and schedule discussion of separate
dedicated function beamlines layout and combined function layout.**

## Minutes

Christoph confirmed that the physics folks were still on track to give
guidance on the upstream location for the IVID in the first half of
July. *(we have omitted this clear action item from our list, I have now
added it\-\--Alan)*. He cautioned that the question about the field and
roll off of the Sumitomo design is an issue under discussion that needs
follow up when our ID folks return from Japan. This will be a topic for
next week's agenda. Alan indicated that he will be on vacation next
week, Bob will chair our meeting.

Bob confirmed that we should be giving priority to the early
commissioning of the soft Xray facility. Rob then handed out cost
estimates for the combination beamline and also the separate function
beamlines, along with a schedule for the separate function plan. (These
documents are included in the Email distribution of these minutes). For
each of the options the Front end is estimated as a double shutter
chicane design at \$619K. The combined function beamline is estimated at
\$2806K , this is still based on the figure for the 10.3.2 monochromator
which is not UHV compatible nor designed for two crystal sets and
multilayers, scope increases which would increase the cost of this item.
Bob indicated that the multilayers are not a high priority and would not
be approved without a clear indication that funding was available to
cover this addition. Rob pointed out that any accommodation of
multilayers in the future could not be achieved by the installation of
these after the monochromator, as had been mentioned last week.
Multilayers must be located between the M2 and M3 optics thus must be
included in the monochromator design from the outset if they are to be
retrofitted later. It was also pointed out that the later installation
of the hard Xray monochromator would be a significant disruption to the
scientific program on the soft Xray section. The cost estimate for the
separate function beamline option is presently at \$3146K. Rob again
pointed out this cost includes the same estimate for the hard Xray
branch monochromator as was included in the combination design option.
The UHV requirement would be eliminated for this mono. Also the
shielding required for the soft Xray branch is relaxed over the
combination option. A "first cut" draft schedule was presented for the
separate beamline option. This schedule indicated that the soft Xray
branch could be completed by August 2004 and the hard Xray by March
2005. These dates are very preliminary and need refining to add
reasonable float and to account for resource availability.
Never-the-less this was considered by the team to be very encouraging as
it looks like the soft Xray branch can be installed in a timeframe
consistent with an IVID delivery by say January 2005, or earlier, and
that the full scope can be completed within the three year target by
October 2005. Based on all the information presented at the meeting Bob
indicated that we should adopt the separate beamline option as our
baseline design. The cost estimate and schedule need further work to
refine the numbers and to produce a more realistic schedule that we can
adopt as our baseline.

Bob commented that we need to get back to our risk analysis as this may
effect our contingency allocations as we firm up our baseline plan.

It was decided that the meeting would now be scheduled from 1:00-2:00pm
. Christoph reminded us that the physics folks have another meeting at
2:00pm thus our agenda must conclude on time. There was enthusiastic
unanimous agreement on this point.

**Action Items (Updated)**

Christoph\-\--resolve upstream IVID location issue.

Christoph/Ross/Steve\-\--resolve ID field and rolloff issues

Rob/Phil\-\--refine beamline cost and schedule estimates, document scope
change request.

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

Dave\-\--set up KOHZU meeting.

Alan---address engineering manpower issues.

Leads\-\--distribute risk analysis forms as appropriate.

Leads---review schedules and update if needed.

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

Steve M\-\-\-- develop IVID procurement strategies with vendor

.

Ross\-\--find out what is known at Maxlab about the in-situ RF heating
and radiation on the cold bore for an installed SCID. Also, since ANKA
and Singapore are placing orders with ACCEL for SCIDs, it would be
useful to know how they have specified the cooling requirements

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.)

Get written approval for the installation of W11 from BCSB
management\-\--Howard?
