1. CTF2 Extension

I. Wilson presented the request from the CLIC team regarding an extension of the running of CTF2 until 29.11.2002 (instead of 25.10.2002), which is of great significance for carrying out further tests before the long period without a 30 GHz power source. Excellent results were obtained recently with the 30 cell tungsten-iris structure which are very important for the CLIC study, but the same gradient is required for pulses ten times longer and the next significant milestone will not be possible until the first part of CTF3 comes into operation for RF power production early 2004. For this reason the CLIC Steering Committee agreed unanimously at a meeting last week that CTF2 should not be operated in 2003 as this would mean a delay of CTF3 and they request an extension of CTF2 in 2002 to obtain as much information as possible regarding the basic design structures before giving up the power source. He showed the CTF3 planning and the programme foreseen for CTF2, followed by the boundary conditions for an extension of CTF2 into November. All groups and services concerned have been consulted. The main difficulty for this extension is in CO Group and B. Frammery explained that due to the large amount of work starting now for the LHC project, priorities have to be set according to the work plan. An extension of CTF2 would result in a one-month delay of the work on the central timing system and installation of new extensions for the SPS. B. Frammery opposed the extension as a matter of principle, but agreed to follow the recommendations of the PSMB. After a lengthy discussion, it was finally agreed to accept the request to extend the operation of CTF2 until 29.11.2002, on the condition that CTF2 is definitely shut down afterwards.

2. CTF3 Collaboration

G. Geschonke reported on the CTF3 Collaboration Meeting that took place last week, which has an important impact on CTF, as well as on the management of other R&D projects in the future. Two representatives of INFN attended the meeting and proposed financial (9 MCHF) and human resources (60 FTEs) for the CTF3 project once a formal collaboration has been set up. A Memorandum of Understanding on the construction of a 3rd generation compact linear collider test facility (CTF3) for a proof of principle experiment for the demonstration of a new distributed high frequency power source has been prepared, in order to set up a formal collaboration, which will be organized in a similar way to experiment collaborations (e.g. Atlas). Each Institute participating in the collaboration will appoint 1-2 people to participate in the Coordination Committee which will decide on the framework of the project and make all decisions as necessary. It is hoped to finalize the Collaboration and Memo of Understanding, plus annexes indicating the commitment of each of the collaborating institutes, by the end of September 2002.

J.P. Delahaye said that this kind of collaboration is exactly what the Member States recommend. CERN must concentrate its resources on LHC but still support other activities despite dramatic reductions for R&D. CERN is encouraged to use resources that exist in the Member State laboratories by establishing formal collaborations with these laboratories to carry out this type of work. In such collaborations, CERN no longer decides on everything, but participates as a member of the collaboration at a level, weighted by the allocated resources, as the other institutes.
