=Eugene=
* the plan is to have beam in the tagger hall in the period April 11-25
** schedule is for swing or weekends to avoid interference with installation
** first to dumplet
** then up ramp and to tagger magnet
* accelerator readiness review, end of August
* Halls/Physics review end of June
* end of this week: director's review
* "Lehman" in two weeks
* project schedule
** we are 6 weeks late with 7 months to go
** implies an average of 420 k$/month
** last month hit 850 k$
** should be able to make it
=Sascha=
* last week ran 25 crates with trigger supervisor
** latency measured
** pulses from signal distribution front panel
** DAQ got stuck after 1/2 hour
*** similar to 12 crate error 2 weeks ago
*** Dave Abbott added monitors on gluon49
* last week changes to CODA
** stand-alone set-up with master TI
** problem could be with optical link, slave to master
* TI board changes came in from William Gu
* new CODA releases: had to back up to previous version
** some features did not work
* work with John Leckey
** debugging with external pulser
** getting intermittent hangs
* Hai has new firmware for BCAL cosmic trigger
** will check, then install in Hall
** trigger for flash as well
=Tim=
* installing hodoscope support frames
* tagger vacuum at 10<sup>-5</sup> Torr
** there seems to be small leak, not a big concern right now
* TOF: supports for steel shields in place
** in 3-6 days lift up onto FCAL frame
* CDC fiducialized
** reflectors being set today
** may go on cart this week
* gas system: close to buttoning up
** ready for leak checking
* electrical power
** help from ACC electricians
** Greg Arnold helping with UPSs
* flammable gas protection system worked out with Dave Kausch
* pair spectrometer mapping started
** Alexandre working on it
* cabling starts tomorrow for CDC
** will be surveyed after it is in
* FDC final z-position fixed tomorrow
=Fernando=
* 3 contract people have been hired
** start assembling new racks for tagger hall
** go on to CDC cabling, Chris will work with them
** will be with us for two months
* TOF will need additional cable trays
* ready to install cables for pair spectrometer and start counter
* CDC has LV and bias cables attached
* wiring plan for LV and bias for tagger microscope done
** drawings sent to Richard Jones
** power supplies will be here end of June or July
* CDC instrumentation
** all crates installed in Hall
** Cody finalizing F125s
* Amtec returned 9 questionable FADC 125s
** 6 are still bad
** some of the boards on-hand work at 40 MHz bus speed, which should be
good enough
** 20 to 25 more modules will be bought from a different manufacturer
=Beni=
* CDC survey: still the same dimensions as when surveyed at CMU
** new survey marks added and fiducialized
** ready for cat
** downstream window a concern: fragile and out-of-sight during installation
* FDC: see about 20 bad channels
** could be ADC problems (off chamber)
** two full connectors disappeared
** some noisy channels
** connected to ground via temporary route, need to check again
* gas system almost read for pressure testing
** need to develop flushing and operation procedures
=Alexandre=
* Wed. not OSP for pair spectrometer magnet mapping
** tested reproducibility, good to a few Gauss
** started mapping at 1.8 T, one dimension, along z
** today: 2 T mapping, 1D, z, at three x positions
** started 1.5 T
** 3D map for 21.8 T, start Wed. go to next week
* NMR probe will not lock
** getting help from magnet group
** did work for a few days
=Elton=
* FCAL
** fixed all problems
** waiting for DAQ to verify
* BCAL
** 2 external scintillators installed for a cosmic trigger
** pulser working with new distribution boards
** upstream chiller working
** downstream need check off from Facilities
** interlock with temperature system not working
* DAQ system working, have some data
** LED data
** cosmic trigger
*** cosmics
*** about 20 counts
*** 2 V full range, 4096 counts
** work on the downstream is next
*** cut conductive sleeves; Anatoly starting tomorrow
*** Chris S. work on distributions boxes for LED
** scintillators: help from Will McG.
=Hovanes=
