32. What will PS2 + SPL provide for LHC?

Michael Benedikt

What will this upgrade bring for the LHC in terms of beam (intensity, structure, emittance and quality) ? Realistic construction schedule including timeline for commissioning of the complex until it can deliver at least the present ultimate beam. Reliability issues as well as the cost of construction and operation of the new complex should be addressed.

33. Keeping the present injector complex running with high reliability for 10-20 more years

Even if SPL and PS2 go ahead, it is unlikely that they will deliver nominal LHC beams before the early 2020’s. This means that the existing LHC Injector chain, SPS, PS & PSB, with LINAC4 replacing LINAC2, will have to continue to run with high reliability for more than 10 more years. This talk will examine what additional actions would need to be taken to ensure that the same Injector chain...

34. Possible improvements to the existing pre-injector complex in the framework of continued consolidation

Massimo Giovannozzi

The situation of the present pre-injection complex will be discussed with particular emphasis on the performance limitations. Mitigation measures will be discussed assuming that substantial consolidation work can be devoted to such improvements. Possible scenarios for the implementation of these measures will be outlined, together with an analysis of the impact on the performance of the LHC machine.

35. Upgrade possibilities in the SPS

The LHC beam with characteristics close to nominal was obtained in the SPS already a few years ago. The main beam-quality limitation comes from the e-cloud effect which seems also to be responsible for high beam losses. During MD sessions in 2008 and 2009 the total intensity of the LHC beam was limited to three PS batches. Intensities above nominal have not yet been seen in the SPS and...

36. Other scenarios for a partial upgrade of the injector complex

Is there an alternative path for a partial upgrade of the injector complex, for example an RCS or FFAG? What would injection at a higher intensity into the PS bring? Would such a solution bring significant advantages?
