2. 2014 achievements 2014 main achievements
Protection devices for high brightness beams - need to attenuate % 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

4. 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
