  1. Summary cavity design & manufacturing Ofelia Capatina (CERN) SLHiPP-1

  2. SPL equipped cavities • Beta = 0.65 • RF design done by IPNO • Mechanical design done by IPNO • Titanium helium tank • 1 niobium cavity to be manufactured by IPN Orsay • To be tested in the “CRYHOLAB” at CEA Saclay • CEA tuner • CEA main coupler Configuration to be tested in CRYHOLAB SLHiPP-1

  3. SPL equipped cavities • Beta = 1, CEA cavity • RF design done by CEA (will be compared later in this talk to ESS design) • Mechanical design done by CEA • Titanium helium tank • 1 niobium cavity to be manufactured by CEA • To be tested in the “CRYHOLAB” at CEA Saclay • CEA tuner • CEA main coupler Configuration to be tested in CRYHOLAB SLHiPP-1

  4. SPL equipped cavities • Beta = 1, BNL cavity • RF and mechanical design done by BNL • Titanium helium tank • 1 copper cavity has been delivered to BNL and the HOM studies has begun • 1 niobium cavity fabrication has started; Cavity fabrication and perform vertical testing in 2012 • The design of the single-cavity cryomodule has begun with the goal to have the cryomodule complete by summer of 2013 • It will be used for Coherent electron Cooling Proof-of-Principle (CeCPoP) experiment in RHIC starting with Run-14 • Antenna-type HOM couplers are being developed • Computer simulations with CST MWS and Omega3P are in progress; The simulation results will be compared with measurements of the BNL3 copper model SLHiPP-1

  22. Cavity RF design : SPL vs ESS DESIGN PARAMETERS DESIGN PARAMETERS SPL ESS RF PARAMETERS RF PARAMETERS Ø96mm Ø140mm Ltot=1393mm Ltot=1315mm SLHiPP-1 Ø96mm Ø140mm Juliette Plouin CEA-Saclay

  23. Mechanicals design • Saclay prototype : possible integration in Cryholab Helium tank in Ti Nb/Ti flanges Helium tank in Ti StainlessSteelflange+coppergasket Bellows (Ti) Intermediatepiece in Ti Bellows (Ti) Intermediatepiece in Ti Intermediatepiece in Ti Helium tank in Ti • Helium tank in Titanium(limits the differentialshrinkagewith Nb duringcooling down) • All flanges made of Nb or Nb/Ti • except the FPC flange, in stainlesssteelwithcoppergasket, to be compatible with the HIPPI coupler, and for safetyreasons • intermediatepiece in Ti needed Helium tank in Ti • Helium tank in Titanium(limits the differentialshrinkagewith Nb duringcooling down) • All flanges made of Nb or Nb/Ti The position of the HOM ports could change after the prototypes, in relation with HOM couplersstudies (SPL and ESS) SLHiPP-1 Juliette Plouin CEA-Saclay

  24. Design : SPL vs ESS • Remark: • Any cavity / helium tank design choice has direct impact on cryomodule configuration and design • ESS cavity, helium tank and coupler design baseline different from choices done for CERN cryo-module SLHiPP-1
