PSI overview
ISIS overview
analysis software mainly used:
- wimda delphi
- mantid (large project), not well matched to what we are doing at ISIS; stopped support for muons in 2020
- musrfit
- some software developed by groups, but aren't used by the community
- the future: number of types and complexity experiments likely to increase
- provide a library core software? We do not need a software which can do everything.
- data format: common format probably not needed (depends on DAQ systems); they have to be properly documented.
- musrfit
- musrfit forum to share better information; just started
- plotting: online tool available, but for offline there are different tools - there is no need to provide something like that
- validation tools: validation scheme saved on zenodo
- major overhaul during long shutdown to ROOT 7
- establish a broader developer base
- flexibility to plug in additional libraries is important
- modularity is essential a lot for new developments (vx-uSR, for example), musrfit has this
- vx-uSR: online define a region to generate histograms in musrRoot; offline one can do everything one wants to.
- access to analysis software. Cloud? There is a STFC server/web site ada where one can do analysis;
- we have only 4 facilities, how can we get things easier to use across facilities?
- the future is likely to be web applications
- use of ai tools: where will it go, how to use?
- open source is essential to keep code alive
AiiDAlab, DFT, MSCP (muon spectroscopy computanional project)
- quantum espresso, login through PSI account; everything goes through the web interface, workflow is saved
- maintained by PSI center for scientific computing
- skeptic about DFT use for the general user, it may take one week to get a result and calculation for various structures may not converge; needs an expert to check
- MSCP now moved to AiiDAlab: using CASTEP & quantum espresso, pymuon, Muspinsim
- "we are developing the same tools too many times are different places"; how can we improve that? Leandro in exchange with PSI people.
mu- (online: Sayani, Chendur)
- EVA
- SRIM/TRIM included
- G4beamline being included for stopping profiles
- MuDirac data base
- nuclear gamma ray analysis from PSI very interenting for both sides
- PSI MuDirac/MOCCA data base.
- EVA & MuDirac/MOCCA data bases are more or less same
- need a meeting with Phil, Mike, Leandro et al
- what's about higher transitions between n=10 to n=20; EVA considers n=10, in MuDirac/MOCCA up to n=20
- using the same data analysis at both ISIS and PSI would be very beneficial
mu- setups
- liquid nitrogen systems to share
- ISIS: 128 channel digitiser from CAEN; standalone 5560SEB, https://caen.it/subfamilies/14-bit-125-ms-s/
- New ISIS instrument MuX
- PSI: tracking of incoming muons, going towards tomography
- tracking at a pulsed source would be also very interesting, but GEM probably do not work... tracking with Si.pixel detectors could work
Beam modelling
- musrSim will be available, if G4Beamline is not continued
- experimental beam optimization
e-learning
- PSI e-learning for musrFit, muon spectroscopy school
- Online learning at ISIS, e-learning.pan-training.eu, lmsweb.stfc.ac.uk;
- costs, who are maintaining things?
- MIXE training at muon spectroscopy school, would be good to have something similar for both facilities
- links to PSI e-learning could be put the ISIS e-learning
expanding the community
- joint PhDs?
- do we have the capacity to grow?
- increase the visibility, APS meetings, European conferences
- something like online seminar, but every 6 months 1/2 day or 1 day
- early career prizes
- help ISMS to develop a strategy, like LENS, thesis prize, engage youg people to join
- News article about our meeting
- engage early career people
