Subject: SA1 status 

Concerning SASE1:

Please note that for this week the "remote power limit" was set to 5 Watt in order to protect CRL1.
The photon energies this week are 5.5 keV (FXE, day) and up to 7keV (SPB/SFX, night).
Daytime SASE1 operation by FXE will not come close to any damage limits (16 pulses at low rep rate).
However, SPB/SFX will operate at 1.1 MHz and up to 356 pulses/train. If there would be a sequence
procedural error during the shift handover switching of parameters, delivery of 5.5 keV at this rate could damage the CRLs.

If this limit would at any point limit the experiment, please get in contact with the PRC.
