   6 - Scope of WP3
   7  * Infrastructure shall be an important scope of ELiTES.
   8  * French group is not a part of ELiTES but we shall ask them
   9    to join the activity by the next telecon.
  10 
  11 - Contamination control
  12  * There are lessons learned at 1G detectors.
  13  * LIGO has a real-time monitor of contamination control.
  14  * Suspension adjustment is to be done with HEPA turned off
  15    and contamination of optics can be an issue.
  16  * On ET side, LMA is in charge of the cleanliness of optics.
  17 
  18 - Vibration isolation of cryo-coolers
  19  * N.Kimura has been working on this for long on the KAGRA side.
  20  * The cryo-cooler vibration has been measured in Rome and
  21    Pisa, but results from KAGRA (CLIO) are important as the
  22    measurement is done with an interferometer
  23  * There are multiple solutions for the isolation.
  24  * Study of residual noise of active systems (ex compressors)
  25    is important.
  26 
  27 - Cooling/Heating time reduction
  28  * Fulvio and Paola are experts on the ET side.
  29  * Helium gas cooling idea etc.
  30  * Discussion at GWADW 2011 with Warren Johnson
  31  * Fulvio will explain the problem with the actual KAGRA setup
  32 
  33 - Scattering light control
  34  * This also belongs to WP2.
  35  * There are lessons learned from 1G detectors about baffles.
  36  * Cooling of baffles is a new issue for ET/KAGRA.
  37 
  38 - Exchange lectures
  39  * Plan to extend the last year's lecture exchange.
