1. Review of Action List
-
Action tracking reviewed using the BIFT Jira board and Kanban.
-
Progress noted on databases and alignment of ISOLDE diagnostics for LS3.
-
Some actions closed; others updated or carried forward to relevant groups.
-
Reference to ongoing action on DB alignment for LS3.
2. Feedback from Operation
-
Operational feedback requested across ISOLDE, nTOF, AD, ELENA, and EA/NA lines.
-
No major urgent follow-ups reported; general operations appear stable.
-
Any specific BI/OP recurring issues to be tracked via the usual channels.
3. BI @ ISOLDE RC6 Line (PUMA) – Responsibilities
Presentation: RC6_Addendum_Presentation & RC6_Mandate_Addendum_BI_firstdraft (provided on Indico).
RC6 Context
-
RC6 is the new ISOLDE beamline enabling isobar-separated beams for the PUMA experiment, integrating diagnostics and mass separation optics.
-
The presentation outlined the rationale for a written addendum to the existing BI mandate, clarifying responsibilities for commissioning, support, and operations.
Key Discussion Points
Diagnostic Scope & Ownership
-
BI responsibility: procurement, integration, calibration, and maintenance of RC6 diagnostics (Faraday Cups, scanners, MagneToF detectors, etc.).
-
Need for clear definitions of responsibility for hardware spares and long-term support.
Operational Modes & Interfaces
-
Two principal RC6 beam modes:
-
Transmission/ISOLDE-like mode (DC beams) for initial setup.
-
Mass-separation mode (bunched beams) critical for PUMA physics.
-
-
Interfaces between BI, OP, STIs, and users were highlighted as requiring documented commitments, especially for software (FESA), cabling, and operational support.
Support Model
-
A pragmatic model was proposed where BI provides best-effort support during working hours and defined expert escalation paths.
-
Operators (BE-OP) to be trained on diagnostics and interfaces; BI retains expert configuration ownership.
4. Round Table
-
Open discussion among core sessions participants reinforcing the need to finalise the RC6 mandate addendum and proceed with implementation planning.
-
No new technical issues raised beyond those in the presentation.
Summary
The meeting reinforced the necessity for a formal written addendum to the BI mandate for RC6 to remove ambiguity in responsibilities, particularly around new diagnostic technologies and operational interfaces. BI actions are progressing, operational feedback is stable, and next steps focus on transitioning from planning to commissioning readiness.
