With 92% it was worse than first year with 94 %. With 99.6% Availability in the last weeks without major outages. Beamlosses partly occured due to beamlines Electron source pulser tests second pulse from new board amended pulse length shorter at lower charge ~100 pC was in operation the last weeks observed energy stability seems to have more jitter than old pulser \u2192 diagnosed to be problem of modulator board measured to feature jitter of ~12ps compared to old one with ~20ps injection rate to booster rather low Debye commissioning measured entire night with -1.3 mm bump @ 85 mA very useful for debugging beamline photo of monochromatic photon beam at end of beamline Problem with old frontend of IR beamline mirror moved and probably tilted large orbit bump and low current required to mitigate vacuum interlocks party today Beam size optimization short unsatisfying shift wrong file loaded in shift before corrected in this shift \u2192 got below 10 um Test of new FOFB bug identified (corrector matrix transposed accidentally) seems to work well now Linac radiation mapping measured radiation dose, waiting for report measured dose rates higher than old measurements with multibunch mode measurements were performed at higher charge than required for operation Single bunch measurements results in RF elog measured zero current bunch length seems to fit prediction within 1% microwave instability confirmed at 3.4 mA somewhat smaller than model (4 mA) maybe due to missing impedance ID and orbit code to compensate for undulator gap change kick was tested working code output pdf in elog local correction with 4 correctors QT GUI not yet working on Bay 4 next time with only local correctors took response matrix data 150 samples for machine learning model X04SA-ID orbit optimization Goal was to callibrate new SiC XBPMs in X04 and compare to existing frontend XBPMs at X04 and X11 beamline was operated during MD shift time was short and current reduced for Debye SU measurements X11 nobody was available to help BPM tild measurement last bpm rotation measurement long ago, lots of HW exchange since then tilt error lets horizontal dispersion appear vertical, making vertical dispersion suppression difficult shift was successful Operator training 5 participants, well recieved explained LINAC setup including different bunchers SME and longitudinal loss monitors with persistent mode showing minimum, maximum, current and average loss worked nicely LLM give nice unique signature of current state of injection losses good to identify drifts and problems early more power in subharmonic prebuncher (SPB) would be good (stronger gradient enables shorter bunch which is good for further bunching and acceleration in 3 GHz structures) idea is to give operators tools/cookbook to double check setup from RF group and correct for long term drifts Requests Time Description Participants Monday, 25.09.2023 \u2060 \u2060 10:00 -

Some example tweets are linked below. All those present at this meeting agree that it is not a good idea to rename the well known name \"SLS 2.0\" which stands for it being the successor to the existing SLS back to the name of its predecessor after commissioning.
