4. Click here to add footer 4 Facts & consequences The quench performance does not meet expectations yet – we would like to see fewer quenches to reach nominal field, less degradation and instability So far, 2 models were made/tested @ CERN: a single coil and a single aperture, 2 coils (105 and 106) out of 3 tested are good (107 being the 3 rd ), which is promising We need to produce more models with the goal of understanding weaknesses and improving performance Which certainly means improving the manufacturing procedures and tooling accordingly Development work is still needed, e.g.: Quench heaters, design, manufacturing, integration Dielectric strength of insulation system Return on experience is needed now for the 1 st prototype and in max. 12 months for the magnets that will installed in LHC during LS2

8. 8 Goals To demonstrate the availability / readiness of the ‘long’ tooling, one needs to launch now the fabrication of the ‘long’ coils for the prototype This is also necessary to get a first prototype tested by the end of 2016 Major design changes are not possible anymore We believe that it is not needed … with RRP cable Model program aiming First, at improving the performance results observed on MBHSP101 and answering fundamental questions Then, at demonstrating credibility of the optional PIT route for LS3

20. Click here to add footer 20 Conclusions – technical viewpoint Operation margin is rather limited, i.e. work point on load line > 80% … bearing in mind that mechanical design is for 12 T No room to manoeuver to increase the margin Integration design requires shortening the collimator. There are two options possible, one with jaws reduced from 800 to 600 mm, and the other one with jaws reduced to 650 mm Detailed study was done to learn with sufficient level of confidence the integration issues A trim circuit is included in the baseline to keep under control the closed orbit without using the orbit correctors; conduction cooled leads provide an acceptable solution The protection in the machine needs to be addressed asap; having a trim current is a complication but not a show stopper The design of the cold mass assembly is well under control, even if not finished, i.e. no show stopper A few items requires careful attention: quench heaters, … Not limited to this presentation

21. Click here to add footer 21 Conclusions – strategic viewpoint It is possible to produce 11T dipoles and have them ready for installation in the LHC machine during LS2 We have a work plan for models. However, it is somehow behind schedule w.r.t. the overall project plan The work plan for models shall focus first on the RRP route, then on the PIT route RRP shall be the baseline for LS2 The program for PIT has to be seen for LS3 We have a work plan for the prototype that is compatible with the overall project plan. However, there is some risk, seen the progress of the short model plan The procurement of the components shall be given high priority in the beginning of 2015, including for the critical components for LS2
