Racetrack Progress and Near-Term PlansWBS 2.3.3.n Peter Wanderer DOE Review of LARP June 12-14, 2006
Topics • LRS: long racetrack + shell support; SRS = short … • 0.3 m SRS tasks (status, schedule) • LBL to BNL: support structure, some parts, cable • BNL - Wind coils, react, pot, assemble, test • 4 m LRS tasks (status, schedule, examples of work) • LBL to BNL: support structure, tooling for assembly: design, build, assemble w. dummy coils • BNL (mostly) + LBNL + Fermilab: wind, react, pot coils, assemble in support structure, test • FY06 Budget overview Peter Wanderer
Short racetrack SRS01 (0.3 m) • Technology transfer from LBL to BNL • also-BNL engineering, technical staff spent time at LBL • Test will begin this week Peter Wanderer
LRS “shell” support structure (4m) • Design of support structure complete • 2D, 3D models • Magnetic, mechanical analysis • Based on 0.3 m SRS support structure • Full-length aluminum shell • Half-length bladders and keys Peter Wanderer
3D LRS support structure design Mechanical Model Magnetic model Model has 300 mm straight section Peter Wanderer
LRS support structure tooling • Handling rafts (green) • Installation beam (purple) Peter Wanderer
LRS support structure status • Procurement: • Shell, tie rods, dummy coils at LBNL (photos) • Assembly rafts fabricated • Pads shipped to LBL • Yoke by end of June Peter Wanderer
LRS support fixture next steps • June - July • Handling structure design & detail drawings • Cradles (detail drawings in progress) • Assembly beam (to be designed) • Winch mounts & pulling structure (to be designed) • Design and fabrication of shell trace • Aug – Sept • Shell instrumentation • Assembly preparation, and pre-assembly • October • Magnet assembly with dummy coils • Load test (pressurize bladders, measure shell tension) • Ship to BNL Peter Wanderer
BNL - coil winding machine Existing equipment Built for LARP 4m coils Peter Wanderer
Lift coil in reaction fixture • Want coil strain < .05% (25% of conductor limit) • Fixture, support beam keep coils strain < .01% • Max deflection 0.003” (0.08 mm) • Two-point support • Lift from center Peter Wanderer
Install coils into support fixture Piston to remove bladders Fixtures from LBL Existing flat support beam Peter Wanderer
Quench protection, instrumentation • Sketch shows concept for coil sides w/o taps, heater. • Quench protection: (4 parallel ss heater strips) X 2 (redundant) • each strip ~ 3, 100A, 0.001” thick; 334 V p.s. • design uses data from LBL dipole HD1 • Instrumentation: spot heater with nearby voltage taps • “Quench origin” voltage taps in critical areas (9/inner coil) Peter Wanderer
LRS01 – LBL/FNAL/BNL items • Items to come from LBNL to BNL: • ProE models of support structure, fixtures that will be used at BNL: July 1 - ok • Support fixture: late October • Item coming from Fermilab to BNL: • Insulated copper practice cable: July 1 - ok • Joint LBNL/FNAL/BNL item: • Insulated Nb3Sn cable: July 15 - ok • Joint LBL/BNL item: kapton/ss instrum. “trace” • Conceptual design completed • Traces needed mid-September Peter Wanderer
LRS01 critical path highlights • Wind copper practice coil: July 1 • Winding base plate, insulated Cu practice cable • Reactfirst Nb3Sn coil: September 19 • Nb3Sn cable due July 15 • Reaction oven due August 4 (a good vendor …) • Impregnate first Cu/Nb3Sn coil: Aug. 1/Oct. 3 • Trace (conceptual design ok) + tooling (in shops) • AssembleLRS01: November 15 • Support fixture, tooling • Test: December, 2006 • Minor test facility work Peter Wanderer
FY06 LRS, SRS Budget • Budget ($k) by institution: total/BNL/FNAL/LBL • WBS 2.3.2.2 + WBS 2.3.2.3 • FY06 – Initial: $1608 / $1262k / $32k / $314k • FY06 – Final: $ 1737 / $1399k / $24k / $314k • BNL increase (items > $10k): reaction oven, coil reaction tooling, winding machine design carryover, copper practice coil (not in baseline) • FNAL decrease: FNAL staff travel to BNL Peter Wanderer
Summary • Schedule • SRS01, LRS01 schedules somewhat delayed, relative to baseline. No fundamental problems. • Rearrangement of magnet construction sequence (SRS02 before test of LRS01), addition of a winding base plate LRS02 still on schedule, Sept. 07, for use in LQ construction decisions. • Cost • Cost growth mostly due to added cost of oven, added scope.
