4. UpdatesKolsterizingAll parts send for treatmentCharacterized within MME (S Sgobba) and validated at coldMagnet in 156Stripping discussed and agreed with MSCBlank assembly being prepared to be ready to give it back to MSC on 25/03Handling and transportTooling in productionTest on 163 crane to validate load and movement OK, crane run smoothly and precisely enough for assembly operationPressure test procedureDiscussed and agreed with HSEDocument under preparationHeat load budgetDocument prepared summarizing all heat loadsTo be shared with CRGDiscussion on-going with CRG to clarify operation, instrumentation and wiring10/02/2021B163 Upgrade Meeting4
5. Lambda plate sealTest of Indium seal on-goingFirst test showedLoss of leak tightness at coldHeat load too high to be measured (cannot reach steady conditions) Probably due to loss of pre-compression at coldNew test on-going with Belleville washer to simulate magnet weight Very good leak tightness at warmCool-down planned for end of this week or next weekIf test is not conclusive : integrated both solutions (vacuum grease and indium) on the flanges to release manufacturing of flange and lambda plate10/02/2021B163 Upgrade Meeting5
6. 10/02/2021B163 Upgrade Meeting6ConclusionsFabrication is going full speed, within schedule and budgetNext step is blank assembly into the magnetTest of lambda sealing solution is still on-going results expected soon
