Minutes of the 60th MTE meeting held on Thursday August 2nd 2012

Present :

J. Borburgh, R. Brown, S. Damjanovic, R. Fernandez Ortega, M. Giovannozzi, C. Hernalsteens, M. Hourican, S. Gilardoni,S. Mataguez

Excused :

1. Most of the design work has been completed, A significant amount of drawings have been finished and are ready for approval and eventual manufacture.

2. The cooling has yet to be finalised, but this is not an issue.

3. Following discussions with TE-VSC a DN150 conflat flange has been installed on the vacuum vessel where extra pumping can be installed if required. This can be suppressed if it is not required. A presentation by vacuum experts is planned for a future meeting.

4. A suitable lifting beam has been identified and is available to do the handling of the complete assembly for installation in the PS ring.

5. A list of possible interventions to estimate the time required from a radiation point of view will be compiled. This list will include a basic rapid intervention (e.g., a leak test) up to a major dismantling and replacement procedure in the event of catastrophic failure (Action: TE-ABT).    

Outstanding Issues

1.  Do we need an impedance screen in the tank (Action: ABP)?

2. Do we need RF type contacts between the Blade support/Blade and the vacuum vessel (Action: ABP)?

3. The final nominal position of the blade has to be determined (Action: ABP).

4. Final shielding configuration still to be defined (Action: TE-ABT).

5. Ray Veness (BI) will discuss with his team and investigate the possibility of adding some form of instrumentation to the dummy septum (Action: BI and TE-ABT).

6. The preliminary look at the shadowing issue will be continued with numerical simulations performed with Fluka and PTC (Action: ABP).
