QXF Testing Plans by LARP
QXF Testing Plans by LARP discuss the development and demonstration of QXF magnets, requiring upgrades to LARP Test Facilities at FNAL, BNL, and LBNL. Significant experience and R&D contributions have been obtained from previous magnet testing efforts. The description elaborates on the upgrades and modifications needed for testing mirror, SQXF, LQXF, and MQXF magnets, along with insights into magnetic measurements, quench protection, and overall testing preparations.

QXF Testing Plans by LARP Guram Chlachidze (FNAL) LARP/HiLumi Collaboration meeting BNL May 7-9 2014
Outline Introduction LARP Test Facilities Required upgrades LARP Magnetic Measurements Quench protection systems Summary 2
Introduction LARP QXF development & demonstration in 2014-2017 1 mirror and 2 SQXF tests 1 mirror and 3 LQXF tests MQXF magnet production and testing follows in 2018-2021 10 pairs of MQXF cold masses to be tested All LARP Test Facilities require upgrade to meet QXF needs, tight schedule is expected LARP test preparation has already started Functional Test Requirements developed for LARP QXF magnets, feedback from CERN obtained QXF Test Facility Workshop at BNL, Dec. 2013, See Ruben s report and related materials here: https://plone.uslarp.org/Workshops/qxftesting/ 3
LARP Test Facilities FNAL, BNL and LBNL test facilities were used for LARP testing at different times FNAL vertical magnet test facility (VMTF) Significant experience obtained from testing LARP TQC/TQS, LQS, as well as HQ magnets Very important R&D contribution obtained from FNAL HFM program Several upgrades/improvements already performed for LARP testing symmetric magnet grounding system active ground fault system Quench recovery system Low dump resistor configurations VMTF dimensions allow LARP SQXF testing at 1.9 K and 4.5 K Upgrades are required to accommodate testing of magnets with 150 mm aperture Quench protection and Magnetic measurement systems also require corresponding modifications 4
LARP Test Facilities (contd) BNL vertical test facility LARP long racetrack magnets tested previously Sufficient mechanical, electrical and cryogenic infrastructure exist Significant experience in magnetic measurements BNL vertical test facility can accommodate LQXF testing at 1.9 K and 4.5 K Modifications required to meet QXF needs LBNL vertical test facility LARP TQS and HQ magnets tested previously at 4.5 K Significant developments in mechanical structure of LARP magnets, magnetic measurement systems and various instrumentation Will be used for instrumentation and hardware development and testing 5
Required Upgrades FNAL VMTF for testing SQXF magnets New header assembly with 150 mm diameter bore New lambda plate with 150 mm diameter bore Instrumentation and wiring for new header assembly and lambda plate New worm finger assembly to accommodate magnetic measurements at reference radii up to 100 mm (CERN requirement) Power leads and all required modifications for CLIQ system FNAL horizontal test stand for testing the MQXF cold mass Stand previously used for the LHC IR quadrupoles Upgrade power leads Design and build warm finger with embedded quench antenna Modify the Return End Can to facilitate 150 mm aperture worm finger assembly Design and build an Adapter Box to accommodate the interfaces between the existing Feedbox and the MQXF magnets Design and fabricate miscellaneous tooling and fixtures 6
Required Upgrades (Contd) BNL vertical test facility for testing LQXF magnets Power electronics and energy extraction system upgrade Signal and data logging system upgrade Service Cryostat Control System upgrade Miscellaneous modifications to accommodate 150 mm magnet bore See details on required test facility upgrades with cost estimate in the BNL workshop report on QXF cryogenic testing by G. Ambrosio and R. Carcagno : https://plone.uslarp.org/Workshops/qxftesting FNAL VMTF and BNL vertical test facilities after required upgrades will meet QXF test requirements Testing all MQXF models at only one FNAL horizontal test facility will be very challenging according to present schedule 7
LARP Magnetic Measurements LARP QXF functional test requirements include preliminary list of magnetic measurements: Z-scan Integral field measurements Loops at different ramp rates Stair step measurements Accelerator cycle measurements Magnetic measurement systems will be developed for LARP QXF magnets Develop set of probes to accommodate all above listed measurements PCB based multi-layer probes are very promising Currently used at FNAL and LBNL Easy to change measurement radius, coil length Need to validate for integrated field measurements 8
Magnetic Measurements (contd) Goal is to achieve sensitivity and resolution of measurements consistent with the LHC/HiLumi field quality requirements Need to develop magnetic measurements protocol together with CERN It will be part of the QXF Test Protocol Integrated QXF measurement plan for all LARP test facilities MQXF measurement plan will be finalized later Based on SQXF and LQXF measurements Reduced number of measurements It will be part of the MQXF deliverables Test plan discussions will start soon Very first SQXF coil test in a mirror structure is expected by the end of year 9
Quench Protection Systems External energy extraction systems 2.5 m and higher dump configurations are available at FNAL and BNL test facilities Accommodate increased number of protection heaters LARP plans to implement Coupling Loss Induced Quench (CLIQ) system Developed and successfully tested at CERN Very promising results obtained during the HQ02b test at CERN Currently working on specifications for CLIQ power leads Basic parameter ranges are selected Leads rated for the highest voltage and current will be selected provided that there is enough room for 3 power leads on the top plate 3 power leads are required to demonstrate full capabilities of the CLIQ system 10
Brief Summary QXF test preparation started LARP test facilities identified for testing SQXF, LQXF and MQXF magnets Testing all MQXF models at only one test facility seems very challenging Functional Test Requirements are developed https://plone.uslarp.org/Workshops/qxftesting/LARP_QXF_Functional_Te st_Requirements_v5.pdf LARP test facility upgrade plans are developed Required upgrades and cost estimates were summarized at the LARP BNL workshop https://plone.uslarp.org/Workshops/qxftesting QXF Quench Protection was discussed at the topical LARP-CERN meeting https://indico.cern.ch/event/311824/ Integrated QXF test plan will be developed soon 11
