| 16 | * CDR status |
| 17 | * JP: highlighted missing chapters/content. Missing chapter to wrong .tex file name. |
| 18 | * JP: Vacuum value discrepancy between FFA & stage 2 beam line, value change to 10^-8 in high energy beam line |
| 19 | * JP: highlighted reference & typo issues. |
| 20 | * WS: to add layout to intro section of WP6 chapter. |
| 21 | |
| 22 | * Engineering |
| 23 | * No updates |
| 24 | |
| 25 | * Simulation |
| 26 | * WS: no update |
| 27 | * JP: New FFA diagram in CDR |
| 28 | * JP: Space between magnets for cavities. |
| 29 | * Discussion on angled cavities - they should introduce behaviour like a cyclotron, transverse oscillations that cancel out turn by turn unless there's a resonance. This should be acceptable. |
| 30 | * The no. turns are also comparable to cyclotron (~1000 cyc. to 10000 FFA) |
| 31 | * JP: potential problem still exists in the proximity of the FFA magnets to the MA cavity core. |
| 32 | * JP: Kickers may still be a concern, they may need making shorter & stronger. |
| 33 | * Worst case, 2 kickers will be needed instead of 1. |
| 34 | * Maximum field on ferrite cavity should be kept < 0.05T (from kicker field) - could be challenging. |
| 35 | * TJK to extend the good field region of the FFA magnet to cover 15 MeV beams in BP1 phase. |
| 36 | * JP: FFA dynamic aperture study added to CDR. |
| 37 | |
| 38 | * AOB |
| 39 | * WS to ask Hywel for PMQ geometry |
| 40 | * 420 T/m field limit |
