<h1> Minutes of the SLS 2.0 Machine Developement Meetings </h1>
|
||||
|
||||
## 20/09/2023
|
||||
|
||||
**Participants:**
|
||||
{{Felix}}, {{Simona}}, {{Michael}}, {{Chris}}, {{Jonas}}, {{Tom}}, {{Andreas}}, {{Anuschka}}, {{Volker}}, {{Lukas}}, {{Jeff}}
|
||||
|
||||
1. **Reports**
|
||||
|
||||
* **Machine Operation**
|
||||
* This year was the worst year in the history of SLS operation. 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 --> 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 --> 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

|
||||
* Communication Strategy and Plan for SLS 2.0
|
||||
* At the last SRDG meeting (https://indico.psi.ch/event/15040/) the new SLS 2.0 communication strategy was mentioned. 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.
|
||||
* End of SLS Party (PSD)
|
||||
* Monday, 25th September, 16:00 - 18:00
|
||||
* Place: tent at the SLS (when facing the SLS entrance, the tent is located on the left hand side)
|
||||
* Please register by Monday, 18th September 2023 in https://indico.psi.ch/e/SLS-party
|
||||
* SLS Letztes Elektron vor dem Upgrade Z'Morge (GFA)
|
||||
* Saturday, 30th September, 07:30 - 09:30
|
||||
* Place: Foyer in front of the Control Room (WGBG)
|
||||
