• septum blade thickness
  • arguments discussed and agreement within participants to keep 2.8 mm as baseline
  • input from tracking studies and parameter scans will be critical to support further developement towards thinner septum
• Machine protection
  • present input from ABT planned for the MP workshop outlines general concept without specific solution yet established
  • possible strategy with passive absorbers in booster-to-collider and collider injection region similar to LHC 
  • Lina raises a point regarding fast RF failure at the higher energy mode and potential impacts due to large energy loss per turn -> will contact directly Angela (ABT contact for MP questions)
• booster to collider transfer
  • Pantaleo suggests that a symetric septa scheme (same device for booster extraction and collider injection) would allow cancelation
  • presently not consider as booster uses thicker septum but should be considered when errors will be explored
• collimation numbers
  • Giulia confirmed the Z-mode collimation scheme has TCS at 11sigma and momentum cut at 1.4%
  • implies BSC at max(11sigma, 1.4+0.3) is very large in the injection region -> need to iterate on the conventional injection bump amplitude required
• Lattice and frequencies
  • Present ABT injection repos use LCC 106.2, will wait for a review of the RF to update beam parameters
  •  Christian noted that ABP acknowledges the impact of beam parameters on injection, but these discussions currently remain within ABP and results will be communicated at a later date
  • Yann asked how this process should be handled so that requirements from the injection process are included. Christian confirmed the question is complex and is still under discussion within ABP
  • Despite other urgent activities Kyriacos has managed to conduct some simulations and will try to share results at a future meeting
