2014 achievements 2014 main achievements Protection devices for high brightness beams - need to attenuate 100-200% more than present design ! Solution found for the TI 2, TI 8 TCDIs – optics (with magnets/power converters), integration, materials, operation/machine protection - Engineering specs being finalised HiRadMat tests being prepared – very important SPS orbit correction –See Giovanni SPS orbit stability Shot-by-shot trajectory variation: Continuous improvements of the MSE current stability – MSE4 and 6 now identical performance (Gilles’ team) Bunch-by-bunch variation: MKE waveform improved (MKE4 con’t) Feasibility studies for the LIU-SPS external beam dump LSS6, LSS4, LSS5 examined – LSS5 concept developed -Bren/Francesco- and retained

2015 challenges 2015 Conclusions Review and finalise all functional specs for all protection devices and dumps Launch design studies and procurements Perform HiRadMat tests Continue orbit/stability studies (MDs) – understand source/test patches Take a decision on performing the External beam dump – needs some remaining CE information Conclusions Thanks to Verena and team for all efforts done and brilliant results. Verena will chair this working group as of Jan/ 2015 – mandate and objectives will be reviewed, in phase with the phase of the project
