1. LIU Wirescanners software
Ana Guerrero Ollacarizqueta
Stephen Jackson

2. Past, Present & Future Past Present Future
2 people were always assigned to LIU WS SW
Loic as primary software designer & developer
Ana acting as Loic’s mentor and source of wirescanner know-how
Present
Loic has resigned. In process of handover of current design done
Ana agreed to take over as primary software designer & developer
Future
Ana will continue development – Business as usual
LIU Wirescanners will be Ana’s main focus
Stephen will act as facilitator, contribute to discussions and ensure we have no shortfall in manpower

3. Latest Software Design (might evolve as more we get h/w spec)
PSB Settings API
PS Settings API
SPS Settings API
Photomultiplier
Motor
Photomultiplier 2
Low-level retrieval and process
Position function computation
Common Acquisition API
BWSLIU FESA class
Expert acquisition property
Low-level FESA class
Data combination
Expert acquisition (and control) exposed in sub-classes, one per hardware device
Result profile (and abstract controls) exposed in main class
Flexible design: variable hardware type/count

4. Initial API Discussions with OP
Handover of 1st software API to OP (promised mid-May)
Meeting went ahead as planned - Business as usual
Even though there are many open-questions on system behavior and parameters
Proposals made for API
Acquisition
SummaryAcquisition
Settings
ExpertSettings
Commands
Arm predefined scan
Disarm predefined scan
Trigger on-demand scan now
Open-questions for OP
Different speeds and calibrations required?, dynamic windowing?, bunch selection?,…
Needs input from Verena and Kevin
Agreed 1st mocked device will have no real-time behavior mocked
Until we know which acquisition board selected
And several more questions are answered (see Ana’s list)

5. Recap of Ray’s Milestones
Software
Draft of firmware-software interface available -
Mar-19
Review of firmware-software interface
Apr-19
Review of software
Sep-19
Working expert application available
Dec-19
Hand-over of software to OP for operational app.
Jan-20
We are delayed by a few months
Principally due to lack of info and pending decisions on h/w

7. Needs & Risks Need for expert tools identified
Unless we have an additional resource, we simply don’t have the manpower
The longer we don’t know all the system characteristics & requirements, the more we risk last minute problems
Combined BISW+BIPM campaign to make a well documented system
Documentation of the FESA class is BISW responsibility
Definition of FESA fields pertaining to hardware registers should come from BIPM
Documentation of the system should come from h/w specs provided and done by h/w team
Ana can follow commissioning of PS wirescanners
But will simply commission software for other instances

8. Conclusion
Ana has agreed to take over as primary software designer & developer
Situation is not ideal but can be helped by
Better inter-section communication
Weekly status meetings (Thursdays 2pm – 30 minutes)
Focus on resolving issues and answering open questions
etc.
Documenting system characteristics/requirements ASAP
By Q we should know everything!
We should try to request additional resources
Loic was providing adhoc assistance and tools for hardware teams
Ana has no spare time for expert tool development
