  1. Status of the SM18 Equipment A. Siemko On behalf of the MTM-TF Team AT/MTM

  2. Outline • SM18 Equipment • 2004 Summary and issues • S4 Equipment • Software/Hardware Consolidation • Foresight 2005 : Risks of Mishaps • Conclusions

  3. Allocation of the 12 Test Benches MB (SSS) F E MB D MB (SSS) SSS (MB) TBB1-S4 SSS (MB) TBD2-S4 C MB B A

  4. Design Test Rate and Throughput Over last quarter of 2004: • Nominal design test rate has been established • Max. design test rate has been confirmed

  5. Status of anticryostats

  6. Status of ceramic shafts and TRU’s

  7. S4 Equipment Three Magnet Families for Testing Taking into account magnet lengths, cold feet positions , jack positions, powering and availability of magnetic measurement systems, Special SSS units were grouped in 3 main families. • Families: • Family 1: 11670 mm, 10715 mm • Family 2: 9310 mm, 8335 mm • Family 3: 6935 mm, 5660 mm

  8. Baseline layout on the SM 18 test benches C F B 8293 mm 6935 mm Extension Module 5660 mm 1275 mm MRB Schematic view of the test bench with the extension module used for the 3rd family (6935 mm, 5660 mm)

  9. The test benches TBB1 and TBD2 are design and procured to accept magnets in 11 mechanical configurations • Dipole configuration • Arc SSS configuration • 9 S4 configurations • First four configurations were tested on TBB1 and relevant equipment commissioned

  10. Chaconsa + SSW Layout for family 1

  11. Chaconsa or TRULayout for family 3

  12. Equipment Dedicated to S4 Testing • The anticryostats • For the magnetic measurements on the test benches magnets must be equipped with the anticryostats • Anticryostats of three new lengths are required • The extension modules • For adapting one type of the anti-cryostat to several magnet lengths of one family, extension modules are required. They will be located between the magnet and the MRB • Three types of rigid extension are required • Wide aperture magnets (ø=70mm) • For Q4 in IR1,2,5,6,8; Q5 in IR2,4,6,8; Q6 in IR4, the adaptation pieces have to be developed in order to fix actual anti-cryostats in wider apertures.

  13. S4 and Arc SSS Anticryostat Production • All components ready, except heating elements for S4 families • Missing heaters are due to be delivered these days (today!?) • Production of additional Arc SSS type anticryostats put on stand-by (waiting for the conclusions of this review)

  14. “Mobile” Chaconsa • All components procured and ready • First system assembled on TBB1 and pre-commissioned (Q9 – family 2) • Support structures of second system are under final assembly stage on the TBD2 • Second Chaconsa put on stand-by.

  15. Software and controls consolidation

  16. Software and controls consolidation

  17. Powering Aspects • All essential equipment is operational • All 13kA commuting switches were upgraded (motorized) • 3 major incidents concerning 13 kA cables encountered over 2004 • Repair has cost substantial effort and resources • Preventive pressure test to be carried out • Two 60/120A commuting switches delivered this week for clusters TBB and TBD • Two 120A Power Converters are still missing

  18. Worries and Mishaps • Although over 2004 all essential equipment was operational and obeying well the design-allocated downtime, the first examples of important equipment wear out and/or mishaps were experienced: • Damage to the anticryostats • Several brakes in case of measuring shafts • Loss of several voltage taps integrated with the current leads • Severe wear out (damage) of the 13kA current lead’s extremities

  19. Worries and Mishaps Silver shoe – TBC2

  20. Worries and MishapsSilver shoe – TBB1

  21. Worries and Mishaps Silver shoe – TBD2

  22. Silver shoe crisis • Series of actions launched, in particular: • Study of two repair scenarios • Procurement of tooling for maintenance and repair • Production of additional spare parts • Due to start soon: • Training of ICS operators • Change of the installation procedures • Procurement of the final tolling for changed procedures (TS resources required!) • Regular preventive inspection and maintenance of the test benches after at most 10 magnet tests

  23. Conclusions • Over 2004 all essential equipment was available and operational, obeying well the design-allocated downtime, in particular this applies to: • Electronics and measuring systems for which the preventive maintenance is in place • Powering – even though several significant mishaps • Controls and software - even though several developments are not completed • Over the last quarter of 2004 the nominal design test rate for the 12 benches has been established and the max. design test rate has been confirmed • Dedicated S4 equipment (already procured and undergoing procurement) will allow to test in SM18 all types of the Special SSS’s • An economic solution was worked out • Major R&D was not needed • Most of the technologies and measuring systems were adapted (redeployed) • The silver shoe crisis receives at present particular consideration! • It has drawn attention to the importance of the preventive inspections and maintenance, even if not anticipated by the design
