BEAM - Beamline
UBL - Upstream Beamline Detectors
BCKOV
Ed LaVallie is assessing US MC7 to come up with the supports for the beam pipe & CKOVs.
TGTW - Target Wheel
CTGT - Cryogenic Targets
NTGT - NuMI (MINOS) Target
Ingrid Fang:
The stationary stand and movable cart drawings were out for bids on September 18, 2002. Quotations will be closed on October 7, 2002 from PalatineWelding, Monarch Corporation, Eagle Stone Inc. and Best Welding.
The assembly drawings for the above project are checked and signed. The flat and double flange wheel attachment can be sent to the machine shop for modifications. The rails mounting holes can be drilled on JGG for installation.
Estimated fabrication period is one month; the assembly drawing is complete.
Peter Barnes:
(see the TPC Electronics Jobs page)
Stick repair progress: Delivered sufficient parts to Bob Jones for his group to power up sticks in a stand-alone mode. Now they can try to diagnose the sticks that don't power up.
New CLK/TRG modules: delivered Bob Jones the diagram and notes for the upgraded CLK/TRG module. He will build two (one is spare).
Set aside one working stick and components to read it out for shipment to Livermore. This will allow us to develop the "Lower DAQ" (TPC readout) software locally.
ZipTrack
Raja:
After some extensive computer archeology, Mike Roman and Doug Jensen have managed to make the Ziptrack Hardware respond to the ZIPTRACK program.
Here are some salient points in our archeological adventure.
- We rescued the MYCOMP Ziptrack computer from its "storage area". It ran Windows 3.1 and Dos ~3. It had 3.6 Megabytes of memory and a 170 MB hard drive that did not work. This is probably attributable to the fact the computer was stored at angle ~135degrees to the vertical underneath a pile of other material. The computer tried to boot up but could not get to the hard drive. The contents of the hard-drive were recovered by Disaster Data Group of California (for $250). They are now on the web.
- Doug Jensen just happened to have a computer that ran Windows 3.1 sitting on his desk. It had only 2 Megabytes of memory. Jerry Zimmerman upgraded this to 32 megabytes using SIMM modules he just happened to have in his collection. We transferred the code from the CD-ROM to the hard drive of this computer.
- The hardware was dusted down and greased by the tech team at lab 8. It now looks almost brand new. J. Krider was able to get the hardware to move using manual controls yesterday.
- Mike Roman had to play with the CAMAC interface. We replaced the CAMAC interface card we salvaged from MYCOMP computer with a spare. After fiddling with the CAMAC /Computer interface, Mike Roman reports that all the Ziptrack functionality is computer-controllable.
- Next step is to get the CART rebuilt. The Hall probes need to calibrated.
- A Labview computer has been acquired from D0 (Rich Smith). It can be used to upgrade the software at a later stage. There is a considerable amount of ASYST software to convert over.
- When MIPP finishes with ZIPTRACK, we will try and store it in a way that is recoverable and reusable by experiments that need it (BTEV, CKM and E906).
System powered up and works, but has minor problems, computer operates but has random hang-ups, cart fabrication probably takes about 4 weeks.

Spaces between coils on the US & DS ends of Rosie need to be shimmed, need to pay attention to water hose routing &endash; Jim Ellermeier;
E690 Chambers
Ingrid Fang:
Chamber 3 Stand design feature being considered is to make the mounting universal for both chamber 3&4. The difficult part of this is the existing hole patterns on both chambers vary and chambers can not be drilled nor welded. I have come up with a plan to accomplish this without having different sets of adapter plates for each chambers.
Transfer frame parts have arrived at Lab 6. Raja is asking Pierrick, with David Miller, Adam, Ed to organize a repair plan. Also Pierrick will have discriminator tower(s) shipped to IIT for testing.
Iowa Chambers
Support stand drawing started 9/19 - about 2 weeks to completed.
Tim Bergfeld:
We did not get the SSAAP grant money. Fortunately, another option has presented itself in the use of the HARP TOF system since they will soon finish running. Preliminary contacts have been made with the HARP collaboration and Dudak does not seem to have a problem with us using it. However, it is owned by Padova. Sanjib will inquire as to our ability to use their system. We need to come up with a negotiating strategy to obtain their equipment. Note that it was approximately a 2.5 x 7.4m TOF wall which they claimed could do 165ps resolution with 21cm segmentation. While we have not seen the results from Raja concerning the thickness of the previous design, we have started looking at the Monte Carlo to understand what a new design with the HARP TOF wall will entail. As such we are reconsidering the use of a second counter which may be placed behind ROSY as suggested again by G. Feldman.
Mirror alignment started, takes about 3 days to complete.Plan to move electronics from PC4 to MC7 the week of 9/30, once the elecronics is at MC7, it will be put into place and the tank closed up.
HyangKyu Park:
This is the update for NCAL by the Michigan group: NCAL consists of two systems, Electromagnetic Calorimeter (EMCAL) and Hadron Calorimeter (HCAL). Basic conceptual design for EMCAL is done. It will be about 1.5 m by 1.5 m, 30 cm in length with weight about 1300 kg. According to Ingrid, the existing NCAL stand design can not hold the EMCAL weight. If Ingrid can modify the design of NCAL stand, we have can only one stand for EMCAL and HCAL. We prefer to having only one stand for both calorimeters. If changing the NCAL stand design is too much work for her, we can go to separate stands for EMCAL and HCAL.
To start the main work for building new EMCAL and mounting PMTs on HCAL, we want the stand made and the HCAL put on the rails as soon as possible. This should be a high priority for MIPP installation.
(Winter is coming here soon. In our experience at HyperCP, the experimental area is very cold to work in during winter.)
Recently we knew that we got the funding from the Academic Alliances grant. So, we can really proceed much faster than before on the major work related to NCAL
EMCAL/Hadron detector design in progress; the support stand for NCAL was designed based upon EMCAL having a weight of 1000 pounds. The hadron detector is now estimated to weigh 3000 pounds. If it is attached to NCAL, some redesign of the NCAL stand will be required. An alternative is to design a separate stand for the hadron detector; also the preferable method is to build the detector in place. However, the support stand will not be ready until about January, so an alternative solution is needed. (HyangKyu Park)

Installing lights, heaters, exit lights.
The next call will be Thursday, 3 October 2002, at 3:00 CDT in WH-11SW.
