Report
-
RTV cookie/mold: The 25-cookie mold table is finished. You can have
a look at the setup on one
of the slides used during the collaboration meeting (picture taken
by Jeff).
-
Cooling system: Tom will probably have the 5x5-array cooling system
ready by wednesday next week. There have been delays due to some account
that had to be setup with ODU.
-
Parts ordering: Artush gave me his first sketches of all the mechanical
parts including the socket, the Al and Ti flanges and the holding ring,
I'm going to hand them over to Larry Munk so he can start having price
estimates.
-
Circuit board: The circuit boards will be available at the end of
the week. We can start checking the circuit board by the beginning of next
week. Once all that is done, I'll hand a floppy disk with the corresponding
ACCEL file to Chris Cuevas so he can start getting price estimates. We
have to move pretty fast now so we can do most of the soldering this summer.
-
9-block prototype: The 9-block protype is in the Moller apparatus.
Eugene told us he had a first estimate of the energy resolution, something
about 10%/sqrt(E), about twice worse than for a clear block. He will tell
us more about it next week.
-
Lucite/Scintillator test: Bogdan told us he observed a factor 2
less counting rate in the lucite than in the scintillator. Both detectors
are sitting at 35 degrees from the beam line.
-
Pb-glass blocks/PMTs: 225 blocks and 200 phototubes sit in the EEL
building now ! As soon as we got the shelves and everything to stock them,
we'll get them out of the boxes.
-
Financing: Kees has agreed for the full funding of the ADCs and
TDCs we need for the experiment. That's a very good news.
