  1. ERL Status & Schedule R&D ERLERL Status & Schedule Gary McIntyre February 17-18, 2010

  2. ERL Status & Schedule • Although important to C-AD, ERL must compete for resources with machine operations – • Sharing resources limits the work that can be performed… • During shutdown periods • Operations maintenance days • Anytime ERL work is in conflict with operations efforts • Best efforts are being made by all ERL-involved groups but schedule slip can and does occur.

  3. ERL Status & Schedule Energy Recovery Linac Milestone Schedule 5-Cell Crymodule to Building 912 10/17/08 Start of Cold Emissions Testing 03/24/09 Gun Cavity begins processing 01/25/10 HTSS testing complete 03/09/10 Gun cavity string delivered to BNL 09/01/10 Gun Cryomodule moved to BLG 912 12/17/10 Sub systems connections to e-Gun Cryomodule complete 02/22/11 Testing start of Gun to 5-cell Cavity Cold with metal cathode 03/15/11 VTF Refrigerator operational 03/23/11 Removal of G-5 components and installation of Injection components 06/01/11 G-5 with Injection (Zig-Zag) Testing Starts 07/18/11 ERL component installation complete & checkout complete 10/24/11 ERL -All Systems- Testing 10/24/11

  4. ERL Status & Schedule • The critical path remains the electron gun cavity cryomodule • Steps to complete the cryomodule include: • Cavity processing • Hermetic Cavity String assembly • String installation into e-Gun cryomodule • G-5 (e-Gun to 5 cell Cavity) next major milestone • Followed by the full ERL complete e-Gun cavity with large grain R&D cavity

  5. ERL Status & Schedule • Cavity Processing – on going at JLab • Buffered chemical polishing - on-going • Vacuum firing to 600C - complete • High pressure rinsing - on-going • Vertical cold testing at 2K - expected start 02/23/10 e-Gun cavity in vacuum furnace (Jefferson Laboratory) Model of e-Gun cavity in Helium Vessel

  6. ERL Status & Schedule e-Gun Cavity Hermetic String Assembly e-Gun cavity in Helium Vessel Fundamental Power Coupler side thermal transition Cathode side thermal transition Assembly/transport cart Tooling design complete – parts of tooling package in fabrication, others in approval loop. All string components in-house or ordered , no negative schedule impact.

  7. ERL Status & Schedule • String installation into e-Gun cryomodule • Cathode transporter in house • Installation tooling design start scheduled for 04/2010 • All cryomodule components ordered with no negative schedule impact Ballast tank Cryomodule vacuum vessel Cathode transporter Cathode insertion point & choke joint High temperature SC Solenoid

  8. ERL Schedule • Major Milestones • G-5 Testing • Requires e-Gun installed in Cryomodule • All major cryomodule components ordered • e-Gun cryogenics lines routing design in process • Requires G-5 magnets, instrumentation and vacuum chambers • All magnets and stands in-house • Installation as time permits • Remainder of G-5 vacuum chambers due 04/28/10 • Beam instrumentation for G-5 & ERL due 08/26/10 • Removal of G-5 “straight” line & install “zig-zag” line • Additional testing with this configuration

  9. ERL Status & Schedule G-5 Layout E-Gun & cathode transporter 5-cell cavity with ballast tank

  10. ERL Status & Schedule • Complete ERL Installation • Requires removal of G-5 Test components • All Loop magnets, stands, and power supplies in-house • All Loop vacuum chambers in-house • Moveable arc stand in-house. • Magnet stand pre-survey underway. • ERL Dump due 03/26/10 • Loop Beam Instrumentation due 08/26/10 • Staging manpower remains biggest challenge

  11. ERL Status & Schedule ERL Layout in Building 912 5-cell Cryomodule ERL Loop e-Gun Cryomodule Laser Room ERL Dump 1MW Klystron 1MW IGBT Power Supply
