4 November 2014 Mike Hourican TE/ABT3 Introduction The objective is to get from this setup in LSS1 To this configuration… This implies, Installation of the new MSI-V Including all supports, vacuum equipment, sector valves, quick release couplings on chambers and on electrical connections

New supports plus all auxiliary equipment Magnets will be stationary, no remote displacement system Magnet Characteristics

4 November 2014 Mike Hourican TE/ABT5 Layout Location SPS LSS1

4 November 2014 Mike Hourican TE/ABT6 remote clamping system Layout description.. and the complications Since this zone is very radioactive (most recent measurements, 22 mSv/h), all manipulations have to be rapid, efficient and safe. Avoid where possible the necessity to bake out the TIDVG (HP water) Plans for external dump may provide relief, but not before LS3.

4 November 2014 Mike Hourican TE/ABT7 Additional vacuum devices + supports Remote handling system for opening and closing flanges on tanks. Note: a rigid support structure is necessary for these devices. We also require a remote operated electrical connection device similar to the MSE/MST Bellows upstream and downstream Sector Vacuum valves-big!

4 November 2014 Mike Hourican TE/ABT8 Layout & Electrical Due to the current measurement precision, a DCCT shall be installed. The DCCT is very susceptible to damage from radiation so it should be installed as far as possible from the TIDVG. This implies positioning the transformers also quite far away. Longer striplines, more inductance and resistance but EPC have confirmed to place them up to 15m away. The remote operated electrical connection (2 off) shall be based on a similar system fitted to the MS. 555 ppm of the reference current. Emittance blow up due to the ripple shall be investigated (JU/TK) Use of the transverse damper shall also be investigated for damping the transverse oscillations.

4 November 2014 Mike Hourican TE/ABT9 Progress Some basic layouts have been studied and a Catia model of the vacuum tank is 50% complete, Costing is underway: Vacuum estimate received from VSC Power supply (EPC) is determined Cost impact from remote handling requirement still to be assessed. Functional Specifications are under review. The first release has been circulated and the second release shall be sent for comments / approval as soon as possible. EDMS. SPU-M-ES-0001 v.0.1 Engineering specification planned by mid ECR to be done.

Some more time required… Increased from initial estimates of approx. 300 and 150 Present apt data based on fact that PSB magnets become available only in LS2. Total resources allocated for time being 1.8 MY. Slightly low, but with some additional help from FSU may be ok. Currently no work units in EVM for ion injection

4 November 2014 Mike Hourican TE/ABT11 Problem areas The additional vacuum devices such as, remote release clamps, have been designed already for SPS (SPS , 6469 and 6470). These devices shall have to be checked and their compatibility with the new system shall be confirmed. If not compatible..? Beam Impedance screen to be designed and integrated Missing resources preparation of magnets can only begin when the SMV10 and SMV20 are no longer necessary in the PSB (PSB 2 GeV upgrade ) or begin dismantling the ‘hot’ reserve magnets at an earlier date (!?) resources assigned to design phase from 2018 only – too late!

4 November 2014 Mike Hourican TE/ABT12 Planning Design and manufacture of MSI-V Dismantling and installation in SPS Realistically one should start the project earlier. Installation in the tunnel seems ok No showstoppers and according to latest planning we have until end Feb to finish

4 November 2014 Mike Hourican TE/ABT13 Conclusions From an original fairly simple task things have changed, Increased complexity has arisen due to remote handling, radiation levels, etc Budget estimate has increased significantly since first proposal Impact of remote handling requirements still not fully clear (budget) Current stability requirement presents more challenges for the EPC team Space requirements for 2 transformers and 15m electrical connections imply more study Should make sure that sufficient resources are available early enough, before the presently planned date (ideally Q2 2016). Engineering / design resources should be available before 2018Currently no budget
