General

  • No user operation.
  • During the week end the accelerator was not able to deliver reliable and stable beam for the user operation.
  • The M2 mirror bender stopped working on Saturday morning and had to be replaced. The mirror and blender were replaced as a whole durig the week end. Normally it would have taker weeks but a "spare" system was already set up for SASE2 and could be used on a short notice. Pumping of the M2 section is ongoing and leak test be performed today.
  • The non working M2 does not show apparent problems so far, and the reason why was not working is not clear.
  • Some sections of the LINAC were warmed up due to some maintenance required for the cold compressors.
  • LINAC is being cooled down and ready for operation today afternoon.
  • The technical support groups were not informed about the problems until saturday afternoon. The communication channels in these cases have to be improved.

    • The goal is to be able to strat the secondo users run on Thursday (Day FXE, Night SPB).
