Description
During the last two years of operation the PS internal dumps and the PSB sieve
showed a significant diminution in reliability. The availability of one PS dump and
of an operational spare is the prerequisite for some modes of operation (e.g. nTOF
in parasitic mode of East hall). The PSB sieve is absolutely required for the
production of the pilot LHC beam. In the SPS the high energy beam dump absorber
(TIDVG) presents signs of beam damage which reduce the mechanical aperture available
for the beam (in particular the high intensity ones).
The current status of this beam intercepting devices, operational issues and the
planned renovations in 2005 will be discussed.
A schedule about the future transfer of responsibility for the stepping motors for
all the collimators of the PS&SPS complex to the ATB group will be given.
