| Cavern Size | Need to hold cavern size iteration in order to allow RRL design to continue. Justin provided history of layout iterations. Layout 2, January 2022: Accommodation of stay-clear and design development resulted in 8' N-S extension. Layout 3, June 2022: Minor adjustment of Layout 2. Layout 4 (current): refinement of design and removal of crane, includes spaces for cleanroom air returns. MM: LRU size? Based on NIF cart. MM: Access to compressor vessel may be more accessible during planned downtimes. BW: Has 3rd dimension been considered? Stack SP diagnostic table? TS: Need design development with Diagnostics Table and Beam Dump. Air plenums - CH: can be smaller, but something has to be there, e.g. thinner double wall plenum. Need iteration with Arup. MM: Being actively worked on between CH and CR. Action is with CH as soon as they have the green light to work with Arup again. T&H - in scope. MM: What does team propose? JG - layout/acess issues. Lack of room for beam transport and associated HW on west wall. MM: new info from Arup - west growth may be possible, but significant add to TPC. Scope reduction may ben necessary. TS: Concern that there is currently no space to spare. BW: Not a new problem - same challenges with LCLS and FEH. MM: Main concern is west wall, including beam dump. BW: Need to push on plenum, so everything can be pushed to east, solving west wall problem. |
