1. BE-BI Software for LINAC4
Specifications
List of BI Systems
Not covered: PSB ring systems
Conclusions
Lars K. Jensen BI-SW

2. Functional specifications:
“BEAM MEASUREMENTS FOR LINAC4 AND ITS TRANSFER LINES”
EDMS Id: (2010)
LIST OF DIAGNOSTICS REQUIREMENTS (observables):
POSITION, INTENSITY AND PHASE (from BPM)

BI software provide interfaces to these observables for client applications
Important points:
Re-use hardware/software as much as possible
(software APIs from LINAC2/PSB systems)
Use 3MeV test-stand for proto-typing
Lars K. Jensen BI-SW

3. BI Systems Date of expected initial use (3MeV test-stand ++):
Faraday-cup
Emittance-meter
SEM-grids
BCT
Beam Wire Scanner
Beam Position Monitor
Beam Loss Monitor
BTV
Bunch Shape Monitor

4. Faraday cup Scope: Present status: Plans: Test-stand + LINAC4
Acquired with local oscilloscope
Plans:
Implement time resolved (cross-calibrated) current readout for LINAC4 source installation (2013)
Movement + High-voltage + ACQ to be specified
Lars K. Jensen BI-SW

5. Emittance-meter Scope: Status: Plans: 3MeV test-stand
Source re-commissioning
Status:
Time resolved beam profiles with HOR/VER slit control
Acquisition and control implemented (FESA/Labview/C++)
Plans:
New slits (allowing for higher energies) by November 2011
RFQ tests early 2012
Minor low-level software changes with no/minimal changes for application
Lars K. Jensen BI-SW

6. SEM-grids Scope: Status: Plans: 3MeV test-stand, LINAC4 (<30MeV)
Acquisition and control for test-stand spectrometer SEM-Grids done (FESA/JAVA)
Time resolved profiles (~6usec)
Plans:
Awaiting final layout decisions
Acquisition/control hardware for final LINAC4 being designed (expected 2012)
Test-stand beam tests during 2012
Lars K. Jensen BI-SW

7. BCTs Scope: Status: Plans:
Test-stand, LINAC4, Transfer-lines (new, old)
Status:
Proof of principle for the acquisition electronics and software during 2011
Time resolved intensity measurements
KHz)
Total current & number of charges
Plans:
Debugging of acquisition electronics and software
Final layout (number, type, position)
Issue with very short beam pulses
Intensity watch-dog (interlock)
Functional specifications on-going (likely combination of hardware and software for added flexibility)
Discussed June 2011
Lars K. Jensen BI-SW

8. Wire-scanners Scope: Status: Plans: Test-stand, LINAC4, new T.L.
Hardware design being finalised
Software to resemble slow ISOLDE scanners (fixed by end Q2 2011)
Plans:
Awaiting final layout decisions
Beam tests foreseen early 2012
Lars K. Jensen BI-SW

9. BPMs Scope: Status: Plans: Test-stand, LINAC4, Transfer-lines
Hardware design/production on-going
HW issue with very short beam pulses
Software will provide:
Time resolved and averaged position values (HOR/VER)
Phase with respect to the RF accelerating frequency
Cross-calibrated beam intensity
APIs by Q3 2011
Plans:
Beam Tests 2012:
3 BPMs on test-stand
Lars K. Jensen BI-SW

10. BLMs Scope: Status: Plans: Test-stand, LN4, Transfer-lines
Hardware design (analogue/digital) on-going
Interlocking spec’s to be finalized
Plans:
Lab tests during Q4 2011
Software design to start Q3 2011
Time resolved losses (2usec)
Integral over 1msec
APIs by early 2012
Lars K. Jensen BI-SW

11. BTVs Scope: Status: Plans: 3 devices in dump line
1 in new transfer-line (?)
3 new in LBE line
4 at PSB injection (stripper foil)
Status:
Reuse existing hardware and software
Plans:
Awaiting specification
Lars K. Jensen BI-SW

12. Bunch Shape Scope: Status: Plans: Test-stand + LN4
Complete system built by JINR (Feshenko)
Status:
Will come with Labview software on PC for test-stand
Plans:
Integration into control system by 2013
Lars K. Jensen BI-SW

13. Conclusions Software design and delivery Operational systems
follows test-stand schedule and hardware availability
Operational systems
deployed and tested when front-end computers become available
Standing agreement with OP
provide APIs ASAP for discussion
3MeV test-stand
Very important for proto-typing
Decisions
Layout must be fixed soon (mainly hardware issue)
Some specifications missing
