Minutes of the Geneva AMS group meeting on July 25, 2000
Geneva AMS group meetings
Davide introduce everybody Dan Welty from Boston. He will document ladder
construction and will write a web page explaining what are we doing with
educational purposes. So if you see him taking pictures just smile... it is
not a spy.
Eric told us the progress about plane modifications. He stressed again the need
of prototypes for vibration tests. One of the problems pointed out this week
has been the metrology on the back plane. Eric propose to use one of the
planes as a jig for the others. Transport boxes are now in production.
No news from PL. Davide, on the other hand, talked with Cicorel. It seems
that Cicorel has problems with the etching and Gandi with the
photoresistance. So a solution could be do the photoresistance at Cicorel (no
problem with that) and the etching at Gandi. This could be the solution for
the kapton business. In order to have the Ni layer, a gold deposit should be
done at Gandi and over there the Ni can be doposited at Cicorel!!!
Giovanni informs that the VAs will be ready by mid october. Also tomorrow
there will be a meeting with the IDEAS assembly engeneer here in Geneva. For
capacitors everything seems OK. CSEM will give us for 'free' 100 pcs with
some defects that hopefuly could be used for prototypes. Finally conectros
will be deliver by Airborne. The communication is open again. As this
conectors where used in AMS01 fligth there should be no problems.
Eduardo presents his 'studies' about reliability. A copy of the
transparencies is here .
Second mechanical prototype (9-ladder long) will be constructed next
week. Schedule for the next prototypes will be decided next meeting (8th
august), but most likely after this second prototype will begin the
construction of the electrical prototype for the test beam next 25th of
