FIFTH MEETING FOR RFQ COOLER AND BUNCHER AT ISOLDE PROJECT

Present: T. Giles, M. Lindroos, A. Jokinen, I. Podadera, D. Porret

Vacuum layout:

• The use of only one forepump for all the turbopumps would imply less contamination and will improve the safety. It would be cheaper.
• As the flow in the forepumps is not very low in our case, Ari proposes that the main turbopump has its own forepump and the other two pumps are connected to the existing ISOLDE system.

Mechanical:

• Everyone agree that it’s better to remove the first insulator with the trailer. It’s not due to remove the trailer more than once every year. If it’s necessary a protection could be thought for this insulator.
• The size that will occupy the controls (vacuum, electronics,…) must be verified.

Control:

• The synchronization between the proton pulse and the bunching electrodes could be made using triggers. All has to be coupled to protons (REXTRAP is already coupled).
• For some experiments is better to optimize RFQ that means they will be an input of the control system.

Next meeting in date to be confirmed.
