2. MQYY: 2 parallel paths Based on a design study carried out at CEA
MQYYM: MQYY short model
MQYY prototypes within QUACO
Based on a design study carried out at CEA
(M. Segreti)
Physical L = 1350 mm endshoe to endshoe
Magnetic Length = 1204 mm at 1,9 K
Outer diameter = 360 mm
OUTLINE:
Status on magnetic design
Status on mechanical design
Status on engineering design
Status on fabrication
Status on magnetic measurement and test preparation
Next steps
Selection of 4 companies to design and manufacture MQYY quadrupole (competitive process 4/3/2 in conceptual/engineering/manufacturing phase)
Starting point: CEA magnetic design
Mechanical design will NOT be provided
Offers have been evaluated by technical committee (JTEC) pending validation by QUACO Steering committee.
Target date for beginning of phase 1 : October 13th 2016

4. MQYYM: update on mechanical design Castem to ANSYS comparison
Identical mechanical ppties
Same assumption on creeping (20 %)
CAST3M has the V2 magnetic version
ANSYS has the V3 version version
Comparison / cross-checks ongoing

5. MQYYM: update on engineering design
MQXC experience discussed with G. Kirby
Assembly plan of MQYYM discussed in detail with Juan Carlos Perez and Arnaud Foussat on June 15th:
Collaring will be performed at CERN by a CEA team assisted by CERN
Yoking will be performed at CERN by a CEA team assisted by CERN
Interface tooling and assembly tooling will be designed and fabricated by CEA based on existing models and drawings provided by CERN. Design to start on October 1st.
Ongoing discussion with J. P. Perez to prepare for CEA team to work at CERN
Tooling Design
Assembly tooling
Procurement
If >5 k€ procurement through CERN
Nordine Azizi / Arnaud Foussat (CERN)
Hubert Neyrial / Hélène Felice (CEA)
Coil fabrication tooling: RFT done, order to be placed soon
End spacers: first 2 sets: RFT done, ongoing negociation
Angular wedges: RFT ongoing
Collars: RFT in preparation
Remaining component design
Connection box
Protection heater
Ground plane insulation
Instrumentation
Complete integration

6. MQYYM: update on magnetic measurements and test preparation
Initial discussion at CERN at the workshop on test facility (June 2016)
No solution for MQYYM
Meeting at CERN on 27/07/2016 with L. Fiscarelli, O. Dunkel and S. Russenschuck
Cold Probe and measuring system will be provided by CERN
Agreement on a probe: 47 mm in diameter, 5 modules of 222 mm in length
Main difference identified between CERN and CEA facilities:
CERN: pressurized bath
CEA: saturated bath (23 mbar )=> concern about freezing the system => design work on the probe mouting ongoing at CEA (JM. Gheller) to ensure sealing, meeting at CERN on 18/10.
Work ongoing on position of probe wrt magnet
Agreement on the fact that the operation of the system will be done by CEA (supported/trained by CERN)
Test Preparation
CAD Modification on an existing header is ongoing.
Hardware modification should start in January 2017

7. MQYYM: Next steps Quench protection :
Simulation with Qtransit and ROXIE. Ongoing work on benchmarking and fine tuning the models
Ongoing preparation of the test
Protection Heater design ongoing
Target completion: mid November 2016
Meeting on conductor to assess the needs to be planned
Conductor available at CEA for first 2 coils
Finalization of the engineering model, components specification and RFT
Target: 1st coil winding by the end of 2016
Becomes tight due to tooling procurement: tooling received at best early December
