LARP Magnet R&D Plan FY 05 -09 LARP Collaboration Meeting, April 26 -28, 2006 Gian Luca Sabbi 2
TQ Model Magnet Goals (1) Phase 1 (TQ baseline): TQS 01 & TQC 01 • Develop and verify the coil fabrication technology • Perform a consistent comparison among mechanical support concepts • Same conductor/cable and same coil design Same fabrication procedures for all coils Consistent instrumentation and documentation Lay groundwork for Lab collaboration - Agree on coil module design and fabrication Share fabrication and instrumentation practices Integrate coil fabrication steps Integrate design, fabrication and testing teams LARP Collaboration Meeting, April 26 -28, 2006 Gian Luca Sabbi 3
TQ Model Magnet Goals (2) Phase 2 (mechanical & conductor studies): TQS 02, TQC 02, TQE 01 TQS 02: reconfigure/optimize based on TQS 01 results • • Adjust pre-load conditions, assembly sequence If needed, replace one or more coils TQC 02: first TQ coils made with “baseline” 54/61 RRP strand • • No changes in the coil/cable design are expected Optimization of mechanical structure w/TQC 01 feedback TQE 01: disassemble TQC 01 coil and test in TQS 01 structure • • Compare coil performance in different structures (evaluate based on TQS 01 and TQC 01 results) Explore the feasibility of collared coil disassembly LARP Collaboration Meeting, April 26 -28, 2006 Gian Luca Sabbi 4
TQ Model Magnet Goals (3) Phase 3 (optimized models): TQS 03 and TQC 03 • Demonstrate the TQ objectives: • consistently achieve G>200 T/m after training and thermal cycle evaluate the required design margins (fraction of short sample) characterize the mechanical performance of the two structures Support the follow-on model magnet R&D: - LQ models: • • • - Provide the optimized coil design for LQ Feedback on coil fabrication methods (integrate with LR) Input for structure selection (integrate with DS) HQ models: • • Design methods/tools and coil fabrication technology Input for structure selection (integrate with DS) LARP Collaboration Meeting, April 26 -28, 2006 Gian Luca Sabbi 5
TQ Models: Original Plan for FY 06 Q 1 -06 Q 2 -06 Q 3 -06 Q 4 -06 Q 1 -07 1. TQ baseline Q 2 -07 Q 3 -07 FNAL LBNL 2. Mechanical & conductor studies 3. Optimized models LARP Collaboration Meeting, April 26 -28, 2006 Gian Luca Sabbi 6
Basis for the Updated Plan • Schedule information from TQS 01 an TQC 01 • More accurate information on sub-task requirements • Need to make up for some delay to support 2009 milestone • Feedback from TQS 01 test • First quench at 80% of “round strand” short sample • Achieved 87% of “round strand” short sample • We have a good basis to build and improve on • TQS 01 & TQC 01 coil fabrication approach was successful • Quality and consistency of fabricated coils • Efficiency of the process: resources and facilities • Program and team integration • Need optimization (cable, end parts, layer transition), but no major changes • TQS 01 test information is available before start of TQC 02 winding • Recommendations from TQ the mechanical review • Extract maximum information at each step; explore variants LARP Collaboration Meeting, April 26 -28, 2006 Gian Luca Sabbi 7
Revised TQ Plan – April 27, 2006 Q 1 -06 Q 2 -06 Q 3 -06 Q 4 -06 Q 1 -07 Q 2 -07 Q 3 -07 Q 4 -07 Complete 8/25/2006 TQ 01 Complete 2/12/2007 TQ 02 TQE LARP Collaboration Meeting, April 26 -28, 2006 Gian Luca Sabbi TQ 03 8
TQ 01 Update Sub-task time increase from FY 06 plan: Coil fabrication: 2 months Mechanical analysis: 2 -3 months Mechanical models: 3 -4 months • TQS 01 training was limited by a localized weakness in one coils • Replacing this coils with a spare (TQS 01 b) should provide useful feedback • Other changes may be considered LARP Collaboration Meeting, April 26 -28, 2006 Gian Luca Sabbi 9
TQ 02 Update • TQ 01 coil fabrication and TQS 01 test results do not indicate any major flaws • Several improvements were identified, but they do not require a cross-section iteration • Coil fabrication process is (finally) well established and optimized • Higher current RRP is required in both TQS and TQC for meaningful comparison • Still missing tooling for coil fabrication in parallel (in particular for winding at LBNL) • TQ 02 can replace the “logical” function that was assigned to TQ 03 in the present plan • Baseline plan would be to provide go-ahead for LQ by the end of the TQ 02 phase LARP Collaboration Meeting, April 26 -28, 2006 Gian Luca Sabbi 10
TQE Update • TQ mechanical review recommended to explore variants • Use of full-round collars in TQC 01 makes coil exchange more realistic • These tests may help select the best structure • Use of pre-tested coils allows to take more risk in investigating design limits • Schedule can be adjusted according to program priorities and “opportunities” • Scope can be adjusted to respond to test results LARP Collaboration Meeting, April 26 -28, 2006 Gian Luca Sabbi 11
TQ 03 Update • Two possible uses of TQ 03 models • Backup in case TQ 02 & TQE does not establish LQ basis • Incorporate any design changes adopted for LQ (one model only) • TQ 03 coils are fabricated in parallel • Schedule includes time for a design iteration LARP Collaboration Meeting, April 26 -28, 2006 Gian Luca Sabbi 12
Long Quadrupole (LQ) • Magnet program plan includes one LQ in FY 08 and one in FY 09 • LQ task needs to start in FY 07 with tooling and practice coils • TQ, LR and DS need to establish target dates for “ok to proceed” • The updated TQ plan is designed to provide answer by mid-FY 07 LARP Collaboration Meeting, April 26 -28, 2006 Gian Luca Sabbi 13
High Gradient Quadrupole (HQ) • Magnet program plan includes one HQ in FY 08 and one in FY 09 • HQ start in FY 07 would be desirable • LQ takes higher priority – can we do both? • Simplified “Phase 1” HQ using TQ coils as inner layer is under study LARP Collaboration Meeting, April 26 -28, 2006 Gian Luca Sabbi 14
Summary TQ: • Some delay, but overall good progress for TQ 01 • Established a performance reference for further optimization • Updated plan takes into account the new information • TQ goal #1: provide the required basis for a timely start of LQ • TQ goal #2: provide the required basis for LQ structure selection LQ and HQ: • Modularity of TQ tooling should allow smooth transition to LQ • TQ coils may be used as inner double-layer for a “phase 1” HQ LARP Collaboration Meeting, April 26 -28, 2006 Gian Luca Sabbi 15
