List of participants:
 Luke Rose, Aleksei Dziuba, Thomas Poschl, Oleg Denisov, George Smirnov, Stefano Levorato, Karl Eichhorn, Fulvio Tessarotto, Jan Friedrich, Christian Dreisbach, Michael Pesek, Eva-Maria Kabuss, Oleg Kiselev, Maxim Alexeev
 
Progress in CERN (Luke Rose)
 - UTS is in clean area in CERN / setted with a readout of ALIDES, which are installed
 - 6 are inside UTS
 - PCB close to power, which cause the problems with connection (5 of 6 running/responding)
  * before all 6 has connection
  * damage of cable or loose connection
  * MOSAIC is fine
  * very unlikely that it's detector is dead
 - we should be careful when unmounting
 - cable is under strong tension
  * spare long ALICE cables don't have proper connector
  * Maxime will check does they have spare in Torino
  * May be something mechanically can be done to make connection pushed
  * Luck will try to push and see if it loose
 - further DAQ test remotely
 - Maxim will come next week and will try to change PCB and cables
 - someone from GSI can come 3-4 days before 19th (if funding will allow)
 - transport from clean area (Stefano)
  * ourself or crain people
  * should not be a problems

  
SciFi's (Jan Friedrich, Karl Eichhorn):
 - Still quite tight in TUM
 - We rather scale down in terms of channels
 - 19th to 26th we will try to have something (from the detector point of view)
 - Fiber machining with diamond sharpened blade:
  * first samples came yesterday
  * now is checking cut quality / news tomorrow
  
Thomas Poeschl: where to put electronics?
Oleg Kiselev: There will be a rack for ALPIDE VME crate, you can use it upper to ALPIDE.
Thomas: ECAL0 rack was a plan
Stefano: There will be pass-by safety inspection from CERN.
Christian will take a care about it.

Christian: Special beam condition (rate, optics)
Jan: 100 GeV muons, 2*10^6, focus nea UTS?
Christian:
 * more less same as for pilot run
 * will be discussed with beam people
Oleg Kiselev:
 * propose to go from lower intensity (known that ALPIDEs live with it) and make several steps to increase
Christian will report next week about it.

 

TPC windows (Oleg Kiselev):
 * vacuum test is done with leakage testing device
 * using existing flange
 * from one direction only (other no possible)
 * no leak of helium at all
 * even no Al protection / everything is work
 * engineer propose don't put Aluminum  since no leakage observed with carbon only
 * outgassing test foreseen
 * long pressure test is also foreseen
 - 100kV feedthrough flange design for pressure test is now under development
