MDus6

MD title: PS injection optics  
Beam conditions:
TOF beam (big emittance needed, intensity not so impo), dumped at flat bottom. Beam prepared by O. Hans

PSB user = TOF
PS user =  MD7

Contact People:
W. Bartmann

Additional remarks:
1) EPC changed the power converter HW limits, so we should be able to change the BTP line settings within the OP working set. Possibility of changing back to LHC settings within the usual cycling time is considered. 2) For both current changes (into dedicated optics and back to nominal) we need support from EPC experts 3) Dedicated BLM mode required to get turn-by-turn loss data
This MD will take place only after the LHC has finished a fill and will possibly not request beam for ~6h. The settings changes in BTP affect the proton operation but not the ion operation (no problems for SPS fixed target physics and MD). Therefore the beam of other parallel PS MDs could suffer from it.
The first part of this MD will take place on Tuesday (preparation with hardware changes) and will require stopping the protons for about ~1h
