## Main remarks
|
|
|
|
|
|
* Till now, ~ 10 BL have started to test BLISS in real conditions.
|
|
|
* Still some SPEC depending on experiments.
|
|
|
* MX BL are now full BLISS
|
|
|
* Q: number of points VS number of intervals
|
|
|
** must allow scans with 0 intervals (ie a count) for coherence in sequences.
|
|
|
* AH: Beamlines could provide test-suite to reduce risks after an upgrade of BLISS
|
|
|
* MB: need for customization over generic tools (kind of "profiles")
|
|
|
* MK
|
|
|
** need to foresee to spend time to test with BEAM :)
|
|
|
** BLISS must be rock stable, we must not deploy too much and to risk
|
|

## General remarks & Discussion

|
|
|
* Till now, ~10 BL have started to test BLISS in real conditions.
|
|
|
* VH, MB: number of points VS number of intervals
|
|
|
- must allow scans with 0 intervals (ie. a count) for coherence in sequences
|
|
|
* AH, JD: Beamlines could provide test-suite to reduce risks after an upgrade of BLISS
|
|
|
* MB: need for customization over generic tools (kind of "profiles")
|
|
|
* MK
|
|
|
- extra commissioning time **with beam** has to be **scheduled** at restart
|
|
|
- BLISS must be rock stable, we must not deploy too much and to risk experiments failures due to BLISS
