1. TDIS simulations plan

5. Actions agreed on TDIS simulations:
Coating (2 µm Cu) vs no coating on graphite blocks. Choice to be done at a later stage. NB
Tapering at jaws upstream/downstream ends. GM BS
Addition of RF fingers in-between the blocks. EB (beam dynamics DA)
Gap b/w jaws. 15mm min. from design point of view (according to latest input from Luca).
(2x graphite) blocks/jaw vs (3x 3D carbon + 1x graphite NB) blocks/jaw. Gaps between blocks: 0.1mm. SA
Loss of one row of jaw side fingers. NB
To measure electrical conductivity of 3D carbon. Inigo to provide sample block. NB + all GM
Impact on beam stability in HL-LHC. NB DA
