From June 23rd :

  1. test regulation box with LOGO Patrick + Student w28

  2. check displays (how many needed and how many available?) Beatrice confirmed all ok for all 3 systems

  3. H2O analysers confirmed all ok for all systems (Beatrice)

  4. O2 analysis Beatrice to check with LPh

  7. Check PI regulation LOGO for mixer 6 gas R&D Patrick(or Steven)

 

 

Hello,

 

I propose to review the small closed loop and mixers status, plan, …. All what is needed.

 

Is Thursday June 23th 2pm in the lab (face to face with the racks) fine with you?

 

Thanks a lot

Roberto
