BEAM - Beamline
Chuck is starting a biweekly meeting, probably 10 AM central time on Mondays, Raja, Peter, others? will be on the distribution list.
All magnets needed for the beamline have been identified.
UBL - Upstream Beamline Detectors
Beam CKOV
Mike says his information on the E907 site is accurate enough for cutting the beam pipe to length for each CKOV.
TGTW - Target Wheel
CTGT - Cryogenic Targets
NTGT - NuMI (MINOS) Target
Ingrid Fang:
As of last week's meeting, it was determined that the current TPC stand needs to support the Hydrogen Target frame. Since neither the Hydrogen Target nor the frame has been designed, the weight of these unit is unknown at this point. I was told by Jim Kilmer that the weight of the Hydrogen Target will be far less than 500 pounds. Assuming the Target frame is made of Aluminum and weights 500 pounds. The total design load applied to the TPC stand will be 1000 pounds.
Based on the above criteria, the current TPC stand design will have an unacceptable vertical deflection of 0.35 inches. My new solution is to install an additional support at the free end, creating a two span system. The current 10.5 feet TPC stand length is not enough to mount the Target frame due to the interference with the manifolds. The gap between the ckov beam and the upstream side of the TPC stand is roughly 4 feet. How much of this can I use?
Design of fixed support stand will be in the drawing queue in about one week; plan to test DAQ software at end of September, at which time the TPC will be installed on its support in the beam line.
JGG - Jolly Green Giant
Rosy
In the next week, Ed LaVallie to write welding spec for Rosie steel.
Procurement to seek a 2nd outside bid for [CKOV rails and cart, and DC#2 stand]:Cost estimate for the rails & cart: Burns Machine - $7389
DC #2
Inner/outer support stand cost estimate:
MAB shop estimates &endash; $10,560, includes G&ABurns Machine - $6438
E690 chambers
Dave will commence bracket design w/in next two weeks.
Iowa chambers
Conceptual design of the supports is complete, in about one week, the design will be forwarded to the drawing queue.
Terry Tope to meet with Martha to discuss C4F10 venting; Dave Northacker mentions Iowa PWCs use Freon 13B1
Testing glue for attachment of PMT to scintillator; Tim Berkfeld has received (I believe) a gird showing Rosie fringe from Bob Wands; Camac chasis for readout will be located DS of Rosie.
Mark Messier reports the PO to go out on 6/27 for five VME readout controller boards. Mark plans to check out operation of the Russian HV supplies next week.WILL the RICH BE SHAKEN TOO MUCH when it is rolled over the rail joints? Jim Kilmer to evaluate; rails are installed and RICH is sitting on its elevated support stands and on the rails.
Alignment
Compiling data from survey of MC5, MC6, MC7 & analysis magnets.
MC7 Building material delivery scheduled for July 15th. Indtallation of materials scheduled for July 22nd.
The next call will be Thursday, 11 July 2002, at 3:00 CDT in WH-11SW.
