FIFTH MEETING FOR RFQ COOLER AND BUNCHER AT ISOLDE PROJECT

SEVENTH MEETING FOR RFQ COOLER AND BUNCHER AT ISOLDE PROJECT

Present: A. Dorsival, T. Fritioff, A. Jokinen, M. Lindroos, I. Podadera, D. Porret, F. Wenander

Mechanical designs:

Tomas remarks that more flanges for the last cross-piece (from 4 cross-piece to 6) could be required in order to use the emittance metter.
Most of the mechanical parts of the project (like supports, cavities,…) will be manufactured in Munich, as part of a collaboration project. The detailed technical drawings must be done ASAP. Help has been required from Ivan to make the technical drawings.
It has agreed that the RFQCB will be assembled in the building 275, and after it can be moved to other place, like the off-line separator, if it’s necessary.
Concerning the mechanical design, Ari agrees that the RFQCB is not necessary that it’s too flexible, as we can optimize all the parameters during the off-line tests and we don’t need to change them during the on-line running.

Others:

Alexandre agrees there is no problem if we have to release the balloons every month instead of one year as it’s made now. In fact, the release time depends on the decay time of the radioisotopes.
Mats requests roof estimation of budget for things to buy before Christmas, apart from the vacuum system and the powe supplies. Mainly, the insulators and things that we need to assembly the device.
It has been accorded that the RFQCB meetings will be held when Ari comes at CERN. While, small meetings with every group for the project will be done.
In the spring, Tomas will be completely available for the project. Mats will look for a support for the technical drawings.

Next meeting in the last week of August (to be confirmed).
