The weekly meeting was held on Monday May,15 and the recent works done
were reviewed. Concerning the TOHM's and the Slow Monopole Trigger the
tests on the attico were completed by Sophia who is also going to bring
back to US some hardware.
The most exciting thing was the completion of the instrumentation of the
WaveForm Digitizer System for all 6 S.M.'s. All the "doughnuts" were wrapped
on the cables and the wire groups nicely arranged on the racks. Tests on the
SM1 WFD in Data Acquisition started but on all the 6 S.M.' s will be completed
by Ed Kerns only when all the processors will be available and mounted on the
system ( most probably next week).
Copying data tapes for the US should be ready soon for batches XD186-193
and XD205-up to last available.
The SM 4,5 and 6 of the PHRASE circuits have been worked on by a team from
Trieste (GG + technical help) and now the full PHRASE system has been modified
in order to provide the low energy trigger for the LIP trigger which Chris
Walter is going to use during these coming days.
The run number 10000 was reached and taken on tape but no special celebration
was organized, there has been a party though on the week end but unfortunately
I was no able to attend due to a strike that forced me to change travel plans.
For details on the party refer directly to partipants.
All the other important achievements of the week can be easily grasped by
reading the following Calendar written by Nat containg the full list of the:
--------
RECENT ACCOMPLISHMENTS:
WFD Clock installed Ed M, Maurizio
LUT work.. all ERP tanks with nominal or higher muon and GC Nat, Kate,
rates, although some still have non-flat responses. Alice, Rich
LUTs are built with recent calibration constants, individual
tank response curves, and lowered MBTs for problem tanks.
SM1 WFD installed, LIP and TOHM readout. Ash, Ed K, Nat
Bob N, Chris W
Fanout repair system setup, fanout repair. Maurizio
Finalize shiftworker duties list. Nat, Bob
Draft and debugging of calibration system MACRO memo. John Hong, Ed M,
Maurizio
Replacing PMTs/bases for TOHM tank-end problems. Kael, Maurizio
Replace 6E06 S&H (TDC problem) and end 1 PMT (TOHM problem). Erik, Ed M
Identify and recable VAX ports on top of detector. Maurizio, Ed M
Preliminary response to CRESST proposal to occupy south end Nat
of Hall B (this is a German/UK cryogenic dark matter search),
while in principle there are no problems, we await responses
to (1) the possibility of helium contamination from the
cryogenic system, and (2) exact placement and access details.
CSPAM refurbishment and threshold resetting. Chuck
Plan for LED switchbox bug fix (to address flakey addressing Chuck
and "fake monopoles" in horizontal boxes).
Reset all horizontal and lower vertical pmt gains to 4 mV/spe. Nat, Chuck, Ed M
Arrival of CAMAC crates (TOHM and spares) John Hanson
Revival of exceptionally nice box-by-box trigger rate monitor. Erik
Rebuild pmt hardware logbooks from assorted scattered Karen
references, scraps of paper, etc.
Repair of HP calibration pulser. Chuck/Maurizio
Rewrite of SCINTSOFT menu and LUT loading/generating software. Nat
New attico TOHM tests (succesful). Sophia

motherboards on SM 6). Ed M, Maurizio
Final WFD power supply check-out. Chris O,
Gianrossano
LED switchbox upgrade, SMs 1-4. Maurizio
ONGOING AND PLANNED PROJECTS:
Fire up SM2 WFD. Ed K, Chris O
