Presentation transcript:

Spectrometer Solenoid – Quench Analysis The LBNL version of the quench model has been further refined - Heng Pan is finishing various quench scenarios Soren Prestemon is trying to arrange a phone meeting w/Vladimir Kashikhin on Thursday to discuss quench analyses - Heng Pan is sending the latest LBNL results to Valdimir An eddy current analysis of the shield will be carried out by Heng Pan to determine if an electrical split line is needed - analysis will look at forces during quench - preference is no split due to tight inner bore clearances Soren has a technician starting to mock up the quench resistor conductive cooling scheme - expect to complete the assembly this week - test should take place next week S. Virostek 4/27/11

Spectrometer Solenoid - Mechanical Design A PO change order to is being issued to Wang NMR this week for the design work associated with the magnet modifications The vendor is beginning work on the details of the design modifications (layout and fabrication drawings) - includes 5+1 cooler layout, new radiation shield, modified shield connection, modified vent/fill lines, new vacuum pump port - vendor expects to complete the design details in 3 to 4 weeks The order for 1100 series aluminum to remake the radiation shields is due in at Wang NMR in 2 to 3 weeks The magnet heat leak calculations will be revisited by Tapio - the vendor will do his own analysis of the modified system S. Virostek 4/27/11

Spectrometer Solenoid - Instrumentation The instrumentation and feedthrough plan has been completed and is being reviewed - Roy is compiling a detailed instrumentation spreadsheet Steve V. and Roy met with an instrumentation rep at Wang NMR on Monday to discuss sensor types – order to be placed this week The current instrumentation plan will be checked by Roy and our LBNL tech to ensure that all sensor types are separated (voltage and He level may be on same feedthrough) We will need to make up new instrumentation cables to match the feedthrough cfg. - it may be possible to reuse the magnet end of the old cables S.
