Keeping Linac2 going until Linac4
Slides
Linac 2 is entering its 29th year of operation and still provides a very high
availability of proton beams for injection into the PSB. The main issues of the
last few years operation will be summarised, and the consolodation foreseen in
the future will be presented.

Controls issues through the backbone
Slides
The LHC injector chain had a difficult restart in spring 2006. Apart from the
major hardware related problems that are discussed in first session, there
were also control issues, in the large sense of the word, that deserve or need
attention. The SPS software big bang is now over and the dust has only just
landed. A brief overview of the encountered problems, the remaining work but...

Rapid SC changes: can it ever work?
Slides
Rapid supercycle changes are essential to ensure best
usage of the machines in theLHC area. Fast cycle
changes can be limited by controls issues, equipment
limitations and magnetic history. Current limitations are
reviewed for the SPS that is now running under the
new LSA control system. Issues of reproducibility at the
PS and PSB will be discussed.

Beam Loss and Radiation with High intensity Beams
Slides
High intensity beams will be a new challenge in term of
losses reduction for the injector complex, in particular at
the PS.
This talk will present the identified sources of losses in
the PS during high-intensity operations, with particular
attention to the CNGS. Possible solutions to alleviate
the impact of the increased irradiation on both the
machine equipments and the area...

Can we make the RF controls in the PS simpler?
Slides
The remarkable versatility of the PS machine comes at the price of the complexity of
its rf beam controls, which never cease to evolve. Historically, these systems have
not only been maintained, but to a large extent, have also been operated by the
specialists who put them together. How can we ensure their operational reliability
when such expertise is becoming thin on the ground?

The SPS Beam Dump
Slides
During the 2006 SPS run problems with the SPS beam dumping system were
encountered. The newly installed beam dump block TIDVG showed strong
outgassing when high intensity beams were dumped on the block. This often
resulted in an interlock of the injection kicker system MKP located close to the
TIDVG and by this stopping the SPS operation. Possible cures for 2007 and
longer term...
