1. Mechatronics Task Force, 26-nov-02 Olivier Teller, CERN EP-CMA1 Cooling Mechatronics Schedule

2. Mechatronics Task Force, 26-nov-02 Olivier Teller, CERN EP-CMA2 Presentation Development plan Milestones Tasks to be completed Schedule Base line

3. Mechatronics Task Force, 26-nov-02 Olivier Teller, CERN EP-CMA3 Development plan SM0 and SM1 as prototype to go in H4 beam SM2 and SM3 as pre serial production Production begins at SM4 SM0 and SM1 probably need retrofitting

4. Mechatronics Task Force, 26-nov-02 Olivier Teller, CERN EP-CMA4 Milestones SM0 has to be ready for H4 beginning of July 03 –SM0 cooling has to be available beginning of May Serial calibration from March 2004

5. Mechatronics Task Force, 26-nov-02 Olivier Teller, CERN EP-CMA5 Tasks Preliminary design –Aim: study of the cooling mechanics principle Choice of the principle of the cooling: –Performed during 26 November Task Force –Agreement about cooling principle Prototype drawings –Duration: 2 months –Drawings for material to be installed in SM0 for test beam in 2003

6. Mechatronics Task Force, 26-nov-02 Olivier Teller, CERN EP-CMA6 Tasks (2) SM0 and SM1 manufacturing –Duration: 3 months –2 SM in order to be able to mount a second electronic solution when 1 SM is in test beam Prototype mounting and tests –1 month for some adjustments –Tests: Leak tests Flow equilibrium between modules Thermal performances

7. Mechatronics Task Force, 26-nov-02 Olivier Teller, CERN EP-CMA7 Tasks (3) Serial drawings –Ended after prototype mounting and tests –some minor modification can be made during tendering Market survey –Cooling bars manufacturing is a special technique: it will probably require a market survey –Has to be launched as soon as possible –Typically 6 months duration

8. Mechatronics Task Force, 26-nov-02 Olivier Teller, CERN EP-CMA8 Tasks (4) Tendering and ordering –Typically 2 months Pre serial manufacturing –2 SM: SM2 and SM3 –Needs the mould development (2 months at least) –Pre serial production needed at least for mechanical fit checks. –After the mounting, drawings corrections (if needed) then agreement about the serial production

10. Mechatronics Task Force, 26-nov-02 Olivier Teller, CERN EP-CMA10 Base line Information coming from the electronic group have been used as the base line in the design. This information becomes requirements now to the electronic. Changing any base line data will impact the cooling mechanic schedule Some information is still needed to finalize the design. Answers are urgent in order to avoid delays.
