27. Reorganization of East Area beam lines

Lau Gatignon

3/6/09, 9:00 AM

As pointed out in previous ABOC/ATC days, the East Area beam lines are difficult to maintain, in particular due the large diversity of the magnets, many of them without spares, and the difficulty to access them whenever a repair is needed. A proposal is presented for a redesign of the area with fewer but more flexible test beams and better access to the equipment in case of failures. The...

28. CNGS Issues

Ilias Efthymiopoulos

3/6/09, 9:30 AM

The successful repair of the facility in 2008, allowed a smooth running with beam throughout the year, collecting in total 1.78E19 protons on target. Record duty cycle operation and daily integrated intensities were achieved towards the end of the 2008 run, after the stop of LHC and FT beams. The gained experience in operating the facility is vital for the understanding of the behavior of all...

29. n-TOF operation in 2009

Vasilis VLACHOUDIS

3/6/09, 10:00 AM

The neutron Time of Flight (n_TOF) facility at CERN is a source of high flux of neutrons obtained by the spallation process of 20 GeV/c protons onto a solid lead target and the remarkable beam intensity of the Proton Synchrotron (PS). From Nov 2008 the n_TOF facility resumed operation after a halt of 4 years due to radio-protection issues. It features a new lead spallation target with a more...

30. Physics requirements in the experimental areas in 2009 and beyond

Horst Breuker

3/6/09, 10:50 AM

Physics requirements in the experimental areas in 2009 and beyond – user requests and planning for for 2009 and beyond. The users schedule for 2009 will be presented. An increase of requests for the various testbeams (considering the upgrade for the LHC, the future ILC and the non-accelerator based experiments) has been observed. For the at present ongoing physics experiments I will give an...

31. Findings and conclusions of the Working Group on Future Irradiation Facilities at CERN

Ilias Efthymiopoulos

3/6/09, 11:20 AM

The need for irradiation facilities to support developments for the LHC experimental particle detectors but also components installed in the accelerator tunnel is clearly identified, and expressed in several proposals and funding requests. To collect the requests from the user community bringing together accelerator, experiment and radiation safety teams and propose a coherent approach for the...

32. Status and plans for CTFIII

Piotr Krzysztof Skowronski

3/6/09, 11:50 AM

The objective of the CLIC Test Facility CTF3 is to demonstrate the feasibility issues of the CLIC two-beam technology by 2010. The combiner ring and the connecting transfer line have been put into operation in 2007, and the remaining parts, namely decelerating section, probe beam linac and test beam line in 2008. In this talk we give the status of the commissioning, including the first results...

37. Mitigation strategies in case of possible magnet failure in the DTL of Linac 2

Richard Scrivens

3/6/09, 12:20 PM

CERN's Linac 2 accelerator is the source of all primary proton beams, and has been in service since 1978. There are sub-systems of the Linac which are difficult to repair, but one main concern has been the inaccessibility of the ~130 quadrupole magnets: the girder supporting the drift tubes (containing the quadrupoles) cannot be lifted from the tank in the Linac 2 tunnel, with the present...
