  1. Status of TCSP manufacturingCollimation Working Group (CWG)24 June 2013A. Dallocchio, A. Bertarelli, F. Carra, L. Gentini, P. Francon, P. MoyretOn behalf of the TCTP/TCSP design, prototyping and manufacturing team

  2. Outlook • MME deliverable • Status of sub-assemblies production: • Movable table • Vacuum tank • Jaw assembly • RF system • BPM cables • Future planning A. Dallocchio – EN-MME

  3. Deliverables • EN/MME to provide EN/STI with 3 TCSP collimators (2 + 1 spare) inside a welded tank (same deliverable as CERCA during Phase I production); STI to prepare collimators for installation. Tank Movable table Jaw assembly A. Dallocchio – EN-MME

  4. Movable table • All tables (6x) available and assembled • Several Tests performed on a (7th) prototype table on test-bench: • 1st complete Lifecycle endurance test (15’000 standard cycles) @ -135˚ • Torque measurement every 5k cycles • Back-driving tests in all orientations without motors • 3 months inactivity • 2nd complete Lifecycle endurance test (15’000 standard cycles) @ -135˚ • Torque measurement every 5k cycles • Back-driving tests in all orientations without motors Tests passed !!! • Surface analysis of bearing shafts after 2 lifecycle tests, EDMS 1136770 A. Dallocchio – EN-MME

  5. Vacuum tank Tests passed !!! • All tanks (3x) assembled and available; cover to be welded after jaw installation. • Leak tests performed to assess the vacuum tightness of weldings and bellows. • Pressure tests performed on vacuum tank cooling circuits as prescribed on manufacturing drawings (30 bars pressure test). A. Dallocchio – EN-MME

  6. Jaw assembly • All jaws (6x) assembled • Components cleaned following prescribed proceduresas specified on drawings: • Coolingpipes, EMDS n. 1210658 • Stainless steel, EDMS n. 1210660 • Glidcop, EDMS n. 1210661 • Copper-Beryllium RF contacts, EDMS n. 1210662 • CFC Jaws recovered from Phase I production, re-machined to fit TCSP taperings (Firing procedure 2hours @ 1000˚C performed again) • Metrology measurements validate flatness requirements on all TCSP jaws, EDMS n. 1275108 • Outgassing test performed on one TCSP jaw without ferrite. Document under preparation by G. Cattenoz. • BPM positioning with respect to active jaw surface within 0.05 mm of tolerance (as specified on drawings) • Pressure tests of cooling pipes 50 bar (20 minutes) Tests passed TE-VSC to formally confirm A. Dallocchio – EN-MME

  7. Jaw assembly – conductance tests • Conductance tests performed by I. Leitao in order to assess quality of jaw brazing . • Acceptance value 7000 W/m2/K (average value over jaw length). • All the 6 jaws are accepted. Conductance tests of TCSP jaws – courtesy of I. Leitao Tests passed !!! A. Dallocchio – EN-MME

  8. RF system RF system conform to UHV requirements BE/ABP inputs to be confirmed • Thermal treatment procedure developed by TE/VSC and EN/MME: 1000 ˚C, 48h in air + 48h under vacuum; EDMS document 1276976 • Firing of 5 ferrite batches already performed (for 3 TCSP + 1 TCTP proto + 1 TCSM proto) • Material for ferrite housing and EM shielding: 316 LN(no CrO coating) • Maximum temperature accepted on ferrite: 100 ˚C (imposed by UHV requirements) • BE/ABP team to confirm the RF-induced losses in operation (end of June?) • RF contacts for end transitions same as Phase I A. Dallocchio – EN-MME

  9. BPM cables • First BPM batch received in 2010; leak tight cables (4 out of 6) used for endurance test on table test bench, to be then re-used for TCSM prototype • 16 pre-series TCTP cables received in July 2012 available for 1 proto and 3 series units • Delivery of TCSP cables still pending; expected by 28th June • Outgassing test strategy for TCSP: 8 cables in one test run;(initial strategy: 4 cables in one test run, to be increased in case of positive results on the first batches) A. Dallocchio – EN-MME

  10. Action list to complete TCSP assembly • BPM cables reception • Measurements of the height of shafts shoulder for the positioning of the jaw into the tank (done) • BPM cables electrical tests (C. Boccard) • BPM cables outgassing tests (G. Cattenoz) • Collimator assembling • BPM cables assembling on jaws • Assembling of RF contacts on the top and bottom of the tank • Assembling of jaws inside the tank and connection of BPM and T cables on the flanges; assembling of flanges + seals • Measurements and tests on assembled collimator • Regulation of end stops and micro switches on 3D machine • Control of position and flatness tolerances of jaws inside the tank • Torque test • BPM test with antenna (C. Boccard) • Further actions before tank closure: • Welding of vacuum caps on the axes • Positioning of tank cover • Torque test before tank welding • Tank cover EB welding • Tests after welding: • Leak test • Outgassing test • Delivery to EN/STI; RF contacts in the transitions + limit switch to be assembled by STI  A. Dallocchio – EN-MME

  11. Time schedule • Delivery of BPM cables by end of June? • After cables reception, at least 10 days needed for electrical + outgassing tests • MME activities (listed in previous slide) take about 4 weeks per collimator • Assembly period right in the middle of summer holidays for most key players! • 6 weeks needed by STI to prepare each TCSP for installation • Optimization of the planning will be performed once BPM cables delivery is confirmed A. Dallocchio – EN-MME
