Minutes WP meeting #89, 12 August 2009
---------------------------------------------------------

Present:
At DESY: Klaus Dehmelt, Ralf Diener, Stefano Caiazza, Jan Timmermans
Via EVO/phonebridge: Ron Settles, Dean Karlen, Dan Peterson, Gilles De Lentdecker,
Jochen Kaminski

Apologies: Takeshi Matsuda

Anybody forgotten?

1) General News: no (general) news 

2) PCMAG news and LPTPC status (Klaus Dehmelt):
- rails for the moveable support structure mounted on the floor of T24 beam area 
  and properly aligned
- tomorrow all frames and tables will be moved in and PCMAG will be mounted into the frame
- pre-cooling with liquid N2 will start tomorrow as well
- for the upcoming LP test (week of 24 August) with the Victoria laser, the Micromegas module
  with "naked" anode will be used
- Dean suggests to take also laser data with a 'high-intensity' beam to see possibly effects of  ions 

3) Nobody present from the Lund, Japan, Saclay/Carlton groups, therefore no news on their
    analyses of test beam data

4) News from Bonn pixels  and GEM modules (Jochen Kaminski):
- MarlinTPC is now modified to handle data from the 8 Timepix chips together, with their
  precisely measured actual positions taken into account
- the DESY group will use the Bonn triple-GEM module, with Altro pad readout electronics
during the week starting 31st August. Jochen will come and help for a few days.

5)  Update on test beam schedule (Klaus Dehmelt):
- the updated schedule is attached to the agenda web page: the shutdown of  the cryo-plant has
been postponed by 2 months; the anticipated shortage of liquid He is now foreseen from
November 9th until mid-March 2010. PCMAG can thus be operated for two more months.
- the DESY group is working on the construction of a LP module with triple CERN-GEMs +
pad readout and modified support of the GEMs. This module might just be ready in time for 
beamtest begin November. 

6) AOB
- the poster prepared by Patrick Conley for the Lepton-Photon Symposium next week is attached
to the agenda page; there is a jpg version (with less resolution, 5 MBytes) and a gzipped postscript
version (10 MBytes, which becomes 25 MB when unzipped). As Patrick is on holidays this week, 
comments can still be sent to Jan till Friday early afternoon.
Dan remarked that besides the LCTPC logo also the EUDET logo was present in the title area
and therefore he requested that the NSF logo would be added; Jan replied that EUDET is not a
funding agency but a collaboration, like LCTPC is. Otherwise many more logos would have to be
added at various places in the poster.
- Jochen Kaminski was still finishing a 2nd poster for LP09, focusing on the pixel readout; 
(the draft version (http://pi.physik.uni-bonn.de/~kaminski/) was sent to the lctpc list the next 
morning for receiving comments) 


Next meeting in two weeks: Wednesday 26 August, 16:00 CET
