Feature highlight: sampling counter modes (#832)
Possibility to select statistics to get from sampling counters
Default mode
+ `SAMPLES` mode: adds a 1D dataset with all acquired values (for diagnostic)
+ `STATS` mode: gives std deviation, min, max, PV, etc.
Activity since last meeting
Improvements to Flint, BLISS data display tool
Meeting organised by Valentin Valls on 2/9/2019 (minutes)
Use cases
Development plan
Follow-up on continuous scan toolbox
- to rely on existing BLISS scanning engine
- need to be as generic as possible
- blocking points have been identified
- BLISS components are not always written the same way
- need to be made uniform
- top-priority item now
Meeting held with BLISS team + E. Papillon, G. Berruyer (#978)
Goal : to provide a "toolbox" (= helper functions) to be able to create optimized acquisition chains for any continuous scan
Follow-up on data saving
Wout de Nolf (DAU) has a working prototype of external data saving (cf. previous Steering Committee meeting) for ID21
See `nxscanwriter` in id21blissutils
BLISS team responsible for data saving: L. Pithan
BLISS releases policy
Meeting held with A. Gotz on 6/9/2019
- One release every month
- Change log to tell about differences, new features, bug fixes, deprecated functions, ...
- Announcement on BLISS mailing list
- Conda package
BLISS team responsible for releases: P. Pancino
Short term planning (from task list)
- Data policy / electronic logbook support (M. Guijarro)
-
Missing features for Lima cameras (S. Petitdemange, L. Claustre*)background, masks, flatfield etc.
-
Continuation on diffractometers support (L. Pithan, E. Papillon*)documentationtests on ID03's 6-circle diffractometer => code finalization
- Wago Tango server using BLISS Wago controller (P. Pancino)
- 100% compatible with the existing Tango server
- support of new interlocks, new Wago TCP module
-
Still on-going: regulation framework (P. Guillou)
September
Replaced by scan toolbox tasks
Linus works on external data saving instead
Short term planning (from task list)
- Finish MCA support (C. Guilloud, D. Naudet)
- documentation
- ROI counters
- data saving -for fast scans-
- Falcon X and other devices
October / November
- Enhanced GUI support (S. Petitdemange, M. Guijarro)
- monitoring framework, compatible with data acquisition
- state passing between peers
- use of distributed locking (leases)
Discussion
Training sessions
-
For external users during Users Meeting : do we confirm ?
- if yes: something simple, basic usage (similar to spec training before)
- beyond BLISS: shouldn't we include information about data policy, electronic logbook etc ?
- Training for BL scientists and beamline staff
- When ? How ?
Newcomer to French CRGs: Benoît Fromet: next week !
- will join forces within the BLISS team
