v3.3.4
Eurizon not yet approved (no official communication about it)
3 DESY colleagues present during the restart of EBS SR from 18th to 22nd August 2022
M4.1.3: Define work organization and contributors to the tasks identified in M4.1.1
Three identified guidelines in M4.1.1 and M4.1.2 :
underlined = Main contributors of a given topic.
1) cross talks: Joachim , Simone
asked magnets colleagues. no results yet . For next time, presentation on status of Cross talks simualtions. interest in GGE. no progress from ESRF side. May have som equivalent from IDM-ESRF group. Paper and presentation to be shared.
2.a) online optimisation during MDT time. Development of online optimisers and MDT software: Lina, Thorsten, Lukas, Bianca. Partecipation to MDT time: everyone. Extreemum Seeker (good for 30params) ? ML? Extreemum seeker: 21st, 22nd, 23rd October possible times for MDT at ESRF with beam.
Etxreemum Seeker: https://github.com/ocelot-collab/optimizer/blob/master/op_methods/es.py
Gausssian Process: https://github.com/ocelot-collab/optimizer/tree/master/GP (harder to set up, optional)
Machine Learning (ESRF taking courses) : see after course if it will be a good candidate. Frist try on skew quad for emittance. May be in october some test.
next-next meeting on optimization.
review of this method next meeting and potential to optimize lifetime.
2.b) Turn-buy-turn optics measurements: Lukas. Nicola
next-next meeting add topic on TbT correction at PETRAIII
some times 5 minutes available, some times few hours. might be difficult to organize. Could be done on zoom.
Lukas: simplest way would be to determine some time , some longer session and invite ESRF in person.
Lukas will propose to set some time for this measurement and will let Nicola know.
3) error and correction tools for pyAT : Simone, Thorsten, Simon, Ilya, Elaf, Joachim, Bianca, Lukas
Simon looking at Response matrix with pandaas
Simone started to rewrite code from matlab to python
Thorsten no progress, but will join work later on.
Elaf started LOCO in pyAT repository? share pyAT lattice for EBS. we will share code repositories as soon as largest debugging is done.
A third meeting for this topic. Speaking on beam threading techniques and how to find closed orbit.
Next meeting is planned for 29th September
Next Restart EBS is in October 2022 20th to 24th
Next Next Restart EBS is in January 2023
Restart times in PETRA III, February or March. Planning not yet known. update on next meeting.
5GeV optics for PETRA III to spare energy?
Nicola C. would be interested in optics correction Turn by Turn. This topic is added above to the list of topics as point 2.b)
Need to look if harwarde is ready at EBS, but we could try to do it at EBS.
