Dear MID colleagues, Svitozar (PRC), Bolko and Shan (RCs),
This morning we faced the situation where MID was limited to 400 pulses (mode M) via the EPS signals. The current RF window set at the machine allows to the requested 450 pulses.
The limiting conditions were the inserted graphite filter (#2) and the diamon screen at the MID Pop-in (#17). After a discussion with experts (and thanking Naresh, Wolfgang and Andreas), both conditions in EPS mode F (see attached) are now disabled, as the current SA2 beam offer safe condition for both devices.
This special situation with disabled EPS signals in mode F is in place until Tuesday 05.Nov as MID will stay at ~12.28keV and with HXRSS (500-600uJ). Please note that in case of either a change in photon energy, substantial increase of photon flux, longer SA RF window or the wish to insert YAG screen at the SA2 Pop-in, these two mentioned conditions have to be enabled again at the SA2 EPS Mode F prior these actions take place.
After the beamtime ends on Tuesday 7AM, either me, Naresh or the PRC will make sure these two EPS conditions are re-enabled.
In case of questions please do not hesitate in contacting me.
Best wishes,
Frederik

**Update Mon 15:00: The beamtime delivery to MID is extended up to Tuesday 9AM. At this moment the EPS signals will be enabled again by Frederik W.-F.
