Progress Updates and Issues

Leon Beverly's meeting summaries in italics.

Upstream Beamline

BEAM - Beamline

Beamline design nearly complete, but Chuck would like a meeting with Peter and Ed to finalize the design; Chuck is also having a Beams designer/drafter to work with Gary to develop a composite drawing of the primary and secondary beamline.

UBL - Upstream Beamline Detectors

Beam CKOV

Mike Heffner needs to decide who will do mirror re-coating; characteristics such as the reflective coefficient and frequency range will impact the cost of re-coating. Jim Kilmer has cost from past coating of RICH mirrors, which have a high quality coating, but costly (~$600/mirror); Jim Kilmer has finalized pipe lengths and given to MAB for cutting. Using Mike's information, Jim estimates there will about 2 feet of space US, 2 feet of space between and 4 feet of space DS of the two CKOV sections. Any BEAMS beam monitors and the 3 &endash; small E690 chambers will be go in the 3 spaces; Another for Mike &endash; what angle resolution is desired for mirror adjustment when manual unit is motorized? The required resolution spec is needed before gears and motors are selected.

Targets

TGTW - Target Wheel

CTGT - Cryogenic Targets

NTGT - NuMI (MINOS) Target

TPC - Time Projection Chamber

Ingrid Fang

Several changes have been implemented into the current TPC support frame stand design based on the discussion with [Peter Barnes] last Thursday.

  1. This stand has been extended 2 feet to obtain more working space.
  2. This stand will be permanently mounted to the concrete pad and will not be connected to the JGG.
  3. This stand will leave a 10 inch gap from the upstream side of JGG to ease the installation of the coil piping.
  4. This stand will be made of Aluminum material with stainless steel connections.

The design is 70% complete based on TPC weight of 2000 pounds. The Hydrogen target weight is not included at this point assuming the target has its own support.

Attached is the sketch [pdf, large gif, small gif inline below] showing the support stand. The blue frame represents the TPC support frame. The green box represents the opening for the copper tubing [cooling the TPC electronics bay]. The red frame represents the TPC base plate. The orange frame represents the stand itself.

Design of fixed support stand 70% complete; current plans are to support hydrogen target (~600 lbs) on a separate stand; some stick repair must take place. The repair can be done any where in MC7. However, eventually a clean room (may also be used to house hydrogen target) will be needed when the cathode plane is installed in the TPC.

Magnets

JGG - Jolly Green Giant

Rosy

A magnetic analysis of Rosie's field indicates the out force on the steel is 106K pounds, the upward force on the steel is 715K pounds, and the force on the side steel (return yoke) has not been determined. Once the force on the return yoke is analyzed, Ed LaVallie will forward to Dave Erickson a specification of the location of welding and/or tie plates that need to be added to the various steel pieces; In addition to the welding, bracing needs to be added between coil saddles on the down stream side of the magnet; Craig Rogers has given a design to Dave for fabricating LCW headers for the JGG.

CKOV - Cerenkov

Gary Smith

Inner & Outer Frames, Cart, and Rails .ps files for CKOV and DC2 [final versions emailed to PDB, will post soon].

Jim Kilmer

Grozis said before he left that he expected the quote from Burns to be here on Friday June 21st. I don't have a quote from MAB yet but Dave promised to finish one for me soon (by Friday).

A cost estimate for the rails and support stand is due Friday, 6/19 from Burns Machine. The MAB shop estimates a direct cost of $8.5K (welder - $2K, fabrication - $5K, material - $1.5K).

DC - Drift Chambers

E690 Chambers

Jeff Norman will continue chamber testing at lab 6, with some assistance yet from Adam; in addition to chamber testing, the maximum cable length between the chamber readout cards and the discriminator chassis and the discriminator chassis and the camac crates will be determined; Dave continues work on wire way/cooling housing for the side of each chamber; Nevis is building xfer frames needed to take apart and repair chambers, estimated completion date is 6 weeks or longer.

IOWA Chambers

Conceptual design of the supports is complete, in about one week, the design will be forwarded to the drawing queue.

TOF - Time of Flight

RICH - Ring Imaging Cerenkov

Leon Beverly

The RICH stands arrived at MC7 today [19 June 2002].

East rail done, move RICH & west rail next, install casters on support stand.

Mark Messier

Sten has the readout controller board ready for fabrication. These are MIPP-specific and we need 4. Sten is going to collect 3 bids and other information by next Tuesday (when I will be at FNAL). The plan right now is for Harvard to write the P.O. for 4 boards. Estimate is ~$1200. These would be the prototypes, but assuming only small modifications are needed we could run the experiment with them.

The front end boards are currently in layout.

Andre succeeded in compiling the kernel for the power PC at Harvard this morning so we're one big step closer to getting the test stand up and running.

Mark Messier reports that four VME readout controller boards will be made; front end readout electronics is still under design by Sten Hansen; Mark plans to check out operation of the Russian HV supplies next week.

NCAL - Calorimeter

DAQ - Data Acquisition

MC - Monte Carlo
