LASA status for medium-beta cavity Paolo Michelato

Talk Overview ESS medium beta SC cavity In kind contribution, prototypes, projects parameters, interfaces etc.. Prototyping activities RF sims & design, HOMs analyses Mechanical design Data and documents management Risk Prototype status: construction, scheduling, cold test Status of series CFTs, procurements … Paolo Michelato, ESS PDR, INFN-LASA, 19 May

Medium beta cavities: Technical Performances MB cavity technical requirements Frequency (MHz) Number of cells6 Geometric beta0.67 Nominal Acc. Gradient (MV/m)16.7 Epeak (MV/m)< 45 RF peak power (kW)1100 Q external Q0 at nominal gradient> Output energy to 570 MeV 36 SuperConducting 6-cells cavity at beta cryomodules, 4 cavity each Independent RF power source for each resonators Constraints: – Cavities will be fabricated using INFN design and will be plug compatible with CEA cryomodule boundary conditions. – INFN design is relative only to the cavity itself. – Cavity interfaces, He tank geometry, flanges, tuner connections, etc will be done on the basis of the CEA design. Paolo Michelato, ESS PDR, INFN-LASA, 19 May

INFN IN-Kind contribution for Medium Beta INFN In-Kind contribution: Niobium procurement for the fabrication of 36 medium beta cavities. Cavity fabrication of 36 medium beta cavities in the industry, including treatments, tuning, Helium tank integration, etc, accomplishing the ESS requirements in terms of performances, functional interfaces, “plug compatible” with CEA design. Documentation, Certification activities, Ancillaries (flanges, vacuum valves, antennas, frames, etc.) Cold test in a qualified infrastructure. Transportation in special boxes and delivery at the cryomodule assembling facility. Man power for the above activities Paolo Michelato, ESS PDR, INFN-LASA, 19 May

Medium Beta prototypes Prototypes plan (not part of INFN in-Kind contribution): Built prototypes of medium beta (MB) and high beta (HB) cavities MB: we are fabricating two MB cavity prototypes with same design but different materials: Large Grain Niobium and Fine Grain Niobium LG and FG are used only for the half cell. All the others components besides HC are done with the same FG material. MB: INFN design, plug compatible with ESS cryomodule Full treatment (BCP, HPR, clean room) done in industry Final handling and test will be done at LASA in the qualified infrastructure. No integration in He tank High beta will be fabricated using LG Nb Paolo Michelato, ESS PDR, INFN-LASA, 19 May

Status at May 2016: EM design: done Mechanical design: done Plug compatibility verified (on drawings). Few details to be clarified. FG material (sheets, tubes, etc) for prototypes: available High RRR LG Nb ingot: available LG ingot slicing (wire cutting): done LG disks heat treatment (de hydrogenation, 700°C for 2 hours): done with H 2 monitoring. RRR check on LG material after heat treatment: High RRR recovered. Prototype status (1/2) Paolo Michelato, ESS PDR, INFN-LASA, 19 May

Prototype status (2/2) Status at May 2016: Deep drawing tool (3 dies) design and fabrication: done First deep drawing of half cells (HC): done First HC mechanical and EM measurements: under way. Activities for the technological transfer of the cavity processing and handling of the industry under way. BCP, HPR, cavity handling in clean room, integration studies, etc Cavity tuning machine refurbishment: in progress LASA Vertical test adaptation for 700 MHz cavities: under way Paolo Michelato, ESS PDR, INFN-LASA, 19 May

The medium beta cavity Paolo Michelato, ESS PDR, INFN-LASA, 19 May

Design phylosophy: -Boundaries fully compatible: Beam pipes, couplers, flanges, tank and tunner connection using the same design of CEA prototype. -We design the cells! Our goal: -To have large cell-to-cell coupling factor, k>1.5% -Allowing for a slight modest sacrifice on E peak and R/Q Design Phylosophy Riris = 5 cm, this large Riris gives us a large k, hence large modes seperation (+30%), also a better coupling of HOMs to the outer cells.
