RFQ test stand (long term) BI developments

Wednesday 25 Jun 2025, 11:00 → 12:00 Europe/Zurich

 

Present: Federico Roncarolo ; Giulia Bellodi <; Jean-Baptiste Lallement ; Edgar Sargsyan , Richard Scrivens

 

We will now operate RFQ2 test bench (with RFQ ready in Aug-Sep 2025). All is ready for this (RFQ BCT and BPM to be installed when RFQ2 moved in final position)

Test bench upgrade document written in 2020 is here:

RFQ_Test_Stand_Future_Proposal_v3_docx_cpdf.pdf

MTP2025 approved full package (basically reallocating budget from RFQ3 production which was canceled)

For BI it is:

Item	Budget	Details
2 x BPMs for ToF	60kCH	"standard" L4 BPM with "standard" DAQ for ToF (present BPM used only via scope for phase meas)
3MeV EM consolidation	30k	Assessment planned for autumn when RFQ test bench starts running
BI-SW grad	90k	Could partially fund new/existing Origin to ensure test bench compatibility with White Rabbit
BI maintenance	25k	For exploitation

Total budget: 205kCH, in principle available from now

Discussion summary:

• All money is available. We should assess if and how we can use it by defining a budget profile from now to Jan 2028
• RFQ test stand master schedule and BI related tasks:
• Sep-Oct 25 to Sep 26 (operate present test stand)
• Measure RFQ2 from : diagnostics as is, to be maintained
• No new BPM installation possible
• Assume present EM will work
• Oct26-Dec27 (prepare for after LS3)
• Can we envisage providing 2 BPMs with DAQ?
• New BPMs may include integration studies (driven by ABP with BI input as needed)
• Any EM modifications to be assessed from experience starting Sep 25 (EM has not been operated for a while)
• Test stand with White Rabbit after LS3: we must ensure HW and SW compatibility → Is it clear what we need to do for BCT, SEM, BPMs? Do we want to pay 1/3 of an Origin with the 90k available here?
• Federico will:
• Discuss in BI, assess available resources, need for new resources
• Get back to ABP via email in July
• New meeting first week of Sep to agree on reasonable budget profile
