Minutes LCTPC WP meeting #115 on October 7th, 2010
=========================================

Present:
At DESY: Klaus Dehmelt, Ralf Diener, Takeshi Matsuda, Volker Prahl, Jan Timmermans

EVO/phonebridge: Martin Killenberg, Gilles De Lentdecker, Dan Peterson, Ron Settles

(anybody forgotten?)

1) (General) News: - Ron attached draft version #13 of the PRC report to the Indico agenda.
                                 The final version will be visible on the PRC public web page
                                 https://prc.desy.de/e38/e59184/
                              - a current list of authors will have to be made; Jan will contact group leaders

2) PCMAG/LPTPC status, testbeam schedule:
- Klaus Dehmelt:  -PCMAG warming up
                   - LP being flushed with N2; have to check the resistor chain as 1 MOhm is missing
                      between the 1st and 7th strip and another 1 MOhm is missing in the main chain.
                    - Will open field cage after the Geneva ECFA meeting
                   

3) News from groups:

DESY (Klaus): will try to have a DESY LP module ready for December
 

Asia (Takeshi):
        - No new results from Japanese groups
        - Observed distortions during last testbeam were due to human mistake in setting
           voltages
        - Trips of GEMs not clear (yet) how to avoid; in any case need more clean operation
           in the lab(s)
        - The group wants a final Asian beam test some time next year, before PCMAG leaves
           to Japan for the cryo upgrade
        - Schedule of PCMAG upgrade: should try to finish the intervention before the end of
          fiscal year "2011", which ends 31/3/2012. This means that PCMAG should leave DESY 
          around June 2011 (the intervention takes ~6 months + travel time)

Dan Peterson: pieces to construct small beam prototypes are coming in and will be available
                      for testing in two weeks time

Martin Killenberg: GEAR description presented last time was with bigger modules

4) WP5 discussions
     - Takeshi mentioned that Peter Schade is working on the calculation of ONE ion disk in 
        the TPC; result not yet presented to collaboration, but he will continue to work on this
        in his spare time
     - Volker Prahl reported that they are producing a 3D model
    
5) AOB: we will organise a few-days LCTPC Collaboration meeting in Japan (probably at KEK)
              in May 2011, preceeding the planned ILD meeting; dates not yet fixed
