Minutes from REX shutdown meeting 2005-11-09

Present: Mats Lindroos, Didier Voulot, Nikolai Trofimov, Nicolas David, Romain Savreux, David Porret, Olga Voznyuk, Stephane Bart Pedersen, Gerrit-Jan Focker, Enrico Bravin and Fredrik Wenander

This meeting was dedicated to the delegation of shutdown work tasks related to REX-ISOLDE. The different support groups, ATB-IF, AB/CO, AB/BDI, AB/PO, AB/VAC, were present and the items on the shutdown lists were discussed with each section. A coarse planning for the AB/RF work was laid out at the last meeting. The shutdown list (continuously under update) is attached.

General points:

* The complete REX-ISOLDE machine is supposed to be operational again 1^st April.

* The low energy part is running until beginning of December

* The REXTRAP may have to provide stable beam for the WITCH experiment during some parts of the shutdown.

* Richard Catherall for the ATB-IF section will inform the workshop of the job requests. A compiled worklist will be provided by Fredrik.

* AB/BDI should give the REX team a cost estimation for the BD consolidation so money can be allocated in the budget of 2006. E. Bravin will deal with this as well as make an agenda for further BD discussions next week. As the BDI workshop is heavily loaded, no extra FCs can be produced this shutdown.

* The AB/BDI group is still testing different options for the beam picture grabbing. A decision which method to use could maybe be taken in mid December. Nikolai T is eager to know if the devices, data types and properties in the control programme will be retained, so he can proceed with the coordination of the control application.

* The vacuum group agreed on doing most of the work during January. For the installation of the recovery balloons and the move of the roughing pumps the coordination and the manpower is still not fully sorted out. REX is at least assured that a move of the roughing pumps can be carried out this year.

* D. Porret was assigned to ask his section leader what the status of and the plan for the vacuum control implementation is. After two years of discussions the vacuum is still operated in manual mode directly at the Simatics panel.
