1. ThomX – Commissioning Meeting – 25/01/2018

2. Meeting organization
Regular meetings every 3rd Thursday of the month (next one 15 February)
Distribution of the agenda, calendar... =>
Working environment:
Mailing list: (11 persons/recipients)
Preparation of the commissioning team (meetings with the different groups)
Already organized: vacuum system, diagnostics, magnets
Next ones: RF cavity, synchronization, control system…

3. Preliminary planning (as for July 2017)

4. Commissioning planning (recent updates)
The planning should be updated and put in TWiki + Atrium (revision of the planning every commissioning meeting)
System of the Safety and Radioprotection: procurement is done in November 2017, all procedures should be finished by the end of February 2018, delivery is expected in Autumn => very important for the beam commissioning to start
ASN authorization request to be send + temporary agreement to start the commissioning of the injector
LINAC: RF gun girder to be ready in March/April 2018, installation is expected in May 2018
RING: vacuum chambers to be delivered in June 2018, vacuum test at LAL afterwards. Transfer of the girders (Build. 208 to IGLEX) in Autumn Kicker + Septum => delivery expected in the end of 2018 or choose another strategy (another producer, temporary alternative injection scheme…)
The commissioning with beam => start in the end of 2018 (beginning of 2019)

5. Commissioning strategy
INJECTOR
Phase I The final assembly and the hardware testing => started/ongoing
Phase II Goal: characterization of the RF-gun + Linac + Transfer Line + Extraction Line
Phase III Goal: reach the injector design parameters. Preparation of the different working points for the SR
STORAGE RING
Phase I The final assembly and the hardware testing => started/ongoing
Phase II Goal: obtain stored beam of sufficient quality
Phase III Goal: reach the SR design parameters
Phase IV Goal: operate with the Fabry-Perot cavity and test the X-ray production
Optimization of the Interaction Point => X-ray production
To be optimized given the problem with pulsed magnets => include different scenarios

6. Commissioning: subsystem status
Installation is completed, alignment checked shortly before commissioning
Radiation protection and safety systems are fully implemented
Synchronization system is implemented and tested
Magnets are installed and checked (PS control, polarity…)
Technical interlocks are tested
Vacuum ideally mbar
RF cavity is conditioned
Feedback systems are installed and tested
All beam diagnostics are installed and tested
All functionality tests are completed
Control system is fully implemented and tested
Injection/extraction system (septum + kickers) is tested or alternative injection scheme for the SR commissioning
All applications are developed for the commissioning

7. HL applications to be discussed during the future meetings
Current status
Save/Restore the machine configuration
First turns applications
BPM test programs
Orbit correction
Optical functions measurement
Tune display and control
ORM measurements
Chromaticity measurement
Injection matching
Closed orbit bumps
Lattice symmetry restoration (LOCO)
Emittance measurement
BBA
Phase I of the commissioning is ongoing (full installation, alignment and the hardware testing phase)
Very important to optimize the start of beam commissioning:
tests of the control system => define timeline and integrate in the planning
setting and testing of the MML configuration/control of the devices
testing of the different hardware on-site with its control system
test of the applications/GUI for commissioning
Organization of the commissioning ( validate and approve the shift schedules, shift team composition, documentation, start-up procedures)
