Recent Experience From Operation & near future Outlook V. Chohan CERN, Geneva, Switzerland Follow-up Review of Reception Tests of CryoMagnets, AT Division, 16 December 2003

Outline Operation Experience since July 03 1. Where are we & Review of 23 July, other Stream-lining Measures � Staffing � To-do-list & Application � Constraints & Limitations in Operation 2. Results to date & explanations 3. Development of OP Tools � SMTMS � Surveillance & Displays � Faults Logging & general Logbook 4. I mprovements Foreseen & Desirable Glimpse at the future Tests Programme and Certain Proposals 16 December 2003 Follow-up Review of Reception V.Chohan tests of Cryomagnets

Talk Abstract • Will attempt to : � Give CONTEXT & CONSTRAI NTS on HOW SM18 Testing Works today � Give a flavour of statistics of all tested magnets via bench occupancy times , explanations & hard limits � With a tongue-in-cheek challenge to connect, cool down & warm up a dipole in 72 hrs ( no cold tests) as expected from I CS & ACR so that we can all benefit from that experience � Forward near Look in testing of Dipoles � I mprovements that are necessary / essential for Operation within the confines of the testing programme as was foreseen. � Show Quench Limits , 2- Quench criterion if that is really the hard cryo limiting requirement & in the light of current magnet performance, � Show way forward for Magnetic Measurement if indeed time saving is desirable and the secondary benefits available if such option is chosen I n addition, will show the setting up of the OP team in staffing , OP Tools necessary, developed & ones that need further efforts to continue successful operation. 16 December 2003 Follow-up Review of Reception V.Chohan tests of Cryomagnets

July 03 Review, its Implementation & other Measures in stream-lining 1. Recommendations were 5. 24 hr MTM piquet started end-Aug, implemented from 23 rd July hence further efficiency in work; this was not the case Feb-Aug 03(upto 22hr evening & To-do-List ( Test work Mon-fri ) programme) modified immediately 6. Availability of New Benches for testing ( E2 -9 Sept, F2 -9 Oct) and with similar 2. New To-do-List is stream-lined, software / hardware as in C cluster for facilitated OP work easy to understand by all OP crew , without complications of certain tests & related problems ( e.g. 7. Stream-lining of magnet tests results storage directly in MTF database 4.4K , many special MM’s, etc..) brought further simplicity in OP work & approach to tests - D.Tommasini 3. Thanks to stream-lined To-do- deserves the exclusive thanks for that. List, the knowledge base required by OP is also reduced and 8. ‘Jackie-boxes’ & trotinette , Ohmic consolidated on the most M’ment ease important tests & principles 9. Traveller clarifications & move of certain HV tests to I CS in Oct 03 4. Availability of Sufficient OP staff to permit 7 day, 24 hr operation ( 10. Establishment of Team Spirit & 6 newcomers from I ndia in July,2 Cohesion amongst Op crew of various in Sept, 2 in Nov & 1 AB recruit in backgrounds & cultures. ( & resolution Oct ) of other problems in housing, transport etc for I ndian Associate ) 16 December 2003 Follow-up Review of Reception V.Chohan tests of Cryomagnets
