M.Jonker CTC-20100601-MPO-WG status

MPO-WG status Small group of people. For many members MP (or even CLIC) is not their main activity. Meetings 16 meetings 19 May – present unfortunately not very regulars

Topics addressed in meetings CLIC layout LHC machine protection LHC BLM system, extrapolated for CLIC Beam Dynamics, faults studies RF Structures, faults and operational aspects MDI implications Implication for and from damping rings. Radiation levels in CLIC main tunnel Safe Beam generation Power Converter implications BLM specifications Rehearsals of presentations, follow up IPAC, CDR

Produced CLIC ACE CLIC seminar Radiation levels in CLIC main tunnel BLM specification requirements Powering implications (availability, Mp issues) Studies for magnet powering TE-MPE seminar IPAC’10 papers

Future topics Opportunities in CTF3 for testing Machine Protection and Operations Inventory of available equipment (problem detection) Inventory of possible intensity ramp-up procedures. Requirements for kicker protections Masks for protecting septa DR extraction, combiner rings, DB turn-around Effects on radiation on electronic equipment MP implications from DB linac Follow up of Damping ring implications (emittance control) Follow up of RF structures implications (Switching procedures) Follow up of Beam Dynamics implications Implications of MP on beam steering (feedback, alignment, …) Collimator protection Fault analysis Operational availability …

Staffing Fellow (Candidate: Carlos Maidana) Collaborator in TE-MPE-MI People participating in MPWG are not fully implicated in MP (or CLIC). Need a larger core of people working on MP issues Other members Fellow (Candidate: Carlos Maidana) Discussion with candidate (Rudiger Schmidt, Daniel Schulte, Michael Jonker) on 8th or 17th of June Simulation of failure scenarios, operational procedures Collaborator in TE-MPE-MI Prototype for machine protection in CTF3 Will initially work with Bruno Puccio on LHC issues Prepare work for CTF3 To be followed up BLM for CLIC (M.Sapinski will start on a different job) Radiation issues (S.Mallow T.Otto)
