Minutes from REX meeting 2005-08-09

Present: Mats Lindroos (chair), Thomas Sieber, Didier Voulot and Fredrik Wenander

General

* Thomas will leave the 19^th of August. A farewell party will be given Wednesday 17^th at 16:00, visitor’s room or outside.

* Mats will be away from 10-29/8, Fredrik from 26/8-4/9 and during the Kr run 12-17/9 (ICIS conf.).

The team was congratulated by Mats for a successful and smooth Sn run.

* Each summary from the experimental runs should have a link from the REX-ISOLDE homepage. Fredrik should deal with this.

* A summary of the Sn and In run is attached to the minutes.

* The Win2000 Linac console computers in the control room hangs. Sylvestre Catin will be asked to deal with it.

TRAP and EBIS

* The cathode will run switched off or run with low power when Didier needs beam for Linac tuning until the next real run.

LINAC

* The 200 MHz amplifier was disassembled this morning. No traces of sparks or thermal stresswas seen on the kapton insulator. That means it could have continued to operate at this low repetition rate.

* A new middle test plate for the capacitor will be produced. The amplifier can be reassembled on Friday or on Monday for tests directly with the resonator. In case the solution with the 3-fold segmented plate does not work out, one can always go back to the old plate.

* Thomas will instruct Didier (and Fredrik) how to start the amplifiers and to setup the Linac from scratch.
