9. RFQ Manufacturing PROCESS
1- Copper + HIP
STARTED (MÉCACHROME)
3- Section manufacturing
DONE (BODYCOTE)
2- Ancillaries
4- Brazing process
(BODYCOTE)
One RFQ section manufacturing’s steps process
ON-GOING (AMD)
B. POTTIN, A-C. CHAUVEAU

10. MANUFACTURING PROCESS according to iphi (PROCESS AND MANUFACTURERs)
Bodycote
Brazing
Machining
Mécachrome
IPHI like
RF validation
Vacuum leak test validation
TriDim
CEA
Bodycote
B. POTTIN, A-C. CHAUVEAU

11. RFQ MéCACHROME PROCESS QUALIFICATION
2 major technical phases to be tested in parallel
Step1
Qualification of deep drilling and machining technic
Validation of process and manufacturer capacity with his equipment
Ultrasound test and tridim measurement
Machining mock-up
Deep drilling mock-up
Step 2
Qualification of vertical brazing process
Validation of manufacturer brazing process
Tridim measurement and leak test
Brazing mock-up
IPHI
B. POTTIN, A-C. CHAUVEAU

12. RFQMANUFACTURING PROCESS QUALIFICATION
ALMOST FINISHED …..
Deep drilling mock-up
Brazing mock-up
IPHI
B. POTTIN, A-C. CHAUVEAU

13. SECTION MéCACHROME PROCESS QUALIFICATION
STARTED…..
Step 3
Qualification of a total section manufacturing : Section 1
Leak test, tridim and RF measurement
To start the series production, the step 3 must be validated
Series production
Sections manufacturing : process adaptation with industrial
Process tracking to optimize the time
Leak test, tridim and RF measurement
Development plan and validation tests according to the qualification phase
B. POTTIN, A-C. CHAUVEAU

14. ANCILLARIES Brazing bi-material Cu-Inox without deposit + TEST cavity

17. REMAINING QUESTIONS
B. POTTIN, A-C. CHAUVEAU

18. Tunnel delivery and assembly
Continuous work with ESS (thank you for good quality exchange with Walter, Georg, Nick…..)
This exchange is necessary because there are continuous changes (good or not.)
It’s not an option to implement the assembly process on the building because we need to see the interfaces, tunnel insertion, space aorund RFQ ….
Saclay to validate strategy and tools
Minimize the assembly time inside the tunnel
Saclay
RFQ support
tools
manutention
bead pull
Truck transport
B. POTTIN, A-C. CHAUVEAU

19. Tunnel delivery and assembly
B. POTTIN, A-C. CHAUVEAU

20. COOLING SYSTEM Cooling pipes implantation
Possible changes from ESS: to decrease the distance between skid and RFQ
 not easy, and final decision must be done
 What is possible inside the tunnel ?
Study by CEA specialist on going
B. POTTIN, A-C. CHAUVEAU

21. LEBT AND MEBT INTERFACES EXAMPLE
Input plate
Output plate
Input and ouput plate design finished.
Next step will be reviewing by ESS for validation
B. POTTIN, A-C. CHAUVEAU

22. OPEN DISCUSSIONS Conditionning procedure and command control :
RFQ Security (Power limitless, temperature acquisition, vacuum level to stop RFQ conditionning…)
LLRF strategy : who? How? When?
We have pick up on the RFQ, we need to speak with ESS what we want ESS must do with pick up information
C&C
We need those systems OK to start conditionning !!!!!
Not only assembly process:
transport from CEA
Delivery
storage before tunnel insertion
storage inside the tunnel
manutention space inside the tunnel
tools…..
I think we need to find time to have small private meetings during these two days to be efficient (for example RF for RFQ)
