| | 20 | * Simulations |
| | 21 | * Slides from JP |
| | 22 | * Analytic field map with doublet FF focussing. |
| | 23 | * Able to obtain the initial working point. |
| | 24 | * Constant tune as a function of KE. |
| | 25 | * Betatron functions. |
| | 26 | * New parameter list. |
| | 27 | * New lattice allows for large variation of vertical tune. |
| | 28 | * CAD |
| | 29 | * Details shown by CH on the layout of stage 1. |
| | 30 | * JP: Distance between len 3 and 4 is critical. Distance between lens 2 and 3 can be adjusted. |
| | 31 | * Further work on the target chamber shown by CH. |
| | 32 | * NB: Progress on FETS FFA engineering details. These details are relevant for LhARA. |
| | 33 | * CH is looking at the vacuum chamber. |
| | 34 | * Need to have strengthening ribs and bellows. |
| | 35 | * This requirement has led to an increase in the magnet gap size. |
| | 36 | * NB: Costing |
| | 37 | * Looking at adding detail to the costing detail used in the PA2 proposal. |
| | 38 | * Discussion. |
| | 39 | * AOB |
| | 40 | * JP: question for CH. What is the size of the wall after lens 2 and is there a shutter? |
| | 41 | * Nominally 0.5m |
| | 42 | * Is the gap on the current diagram sufficient? |
| | 43 | * Need to do a radiation study. |
| | 44 | * The size of the wall is important for the injection line. |
| | 45 | * RR: Message from WS re submitting an abstract for the NPL workshop. |
| | 46 | * Consensus is if WS can submit one then that is good. |
