     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.

     39        * WS to ask Hywel for PMQ geometry
