Draft March 15 2006MERIT BNL Pulsed Magnet –In the PTF Test CellPlan For: MIT Plasma Science and Fusion CenterPre-Operational Testing of:MERIT Magnet and ORNL Mercury Target Neutrino Factory and Muon Collider CollaborationDraft March 15 2006Introduction The MERIT magnet has undergone pre-operational testing and is consideredoperational. The next phase of testing involves the addition of the Mercury Jet systemsupplied by ORNL. With the completion of these tests, the magnet and Mercury jetsystem will be shipped to CERN for proton beam tests. Tests planned for MIT have been estimated in Appendix A. There has been some commentary on the number of tests. Based on an email from Kirk McDonald, fields lower than 15T are expected to be less interesting. There may be some experiments without field, and there may be some experiments with low field. For costing, allow for 18 equivalent full field pulses. This is 12 15T shots plus some number of lesser shots. It isexpected that if a nozzle change is needed, this will be decided before all the full field shots are done. We will expect two cooldowns from room temperature.Description of Tasks: Preparation for the Mercury Tests Attend Mercury safe handing course, and have technicians familiarize themselves with the MIT role in the Mercury testing. Mercury jet tests are the responsibility of Oak Ridge, but operation of the power supplies, magnet diagnostics, and liquid nitrogen system are the responsibility of MIT. No MIT travel is anticipated.Train technician to operate the power supplies. Phil Michael will train Dave Tracey for the “production run” of ORNL Tests. Design and procure (through BNL purchasing) pressure relief and burst disks acceptable for CERN use as well as with ORNL testing.Receive, and off load the Mercury jet system. This will comparable to the effort to offload the MERIT magnet when it arrived from CVIP.Disconnect MERIT Magnet, and store clear of the lift path of the Mercury jet cassette. Clear the column supporting the PTF test stand. Lower Mercury system with the common base plate into the area in front of the PTF split pair magnets. MIT technicians willoperate the crane, ORNL will provide the lift rig for the Mercury jet.Retract jet assembly – This will be done by ORNL but some techsupport is expected.Lower the MERIT magnet onto the common baseplate. Insert the mercury system- This will be done by ORNL but sometech support is expected.Adjust the angle of the system. This will be done by ORNL but some tech support is expected.Re-manufacture vertical bus bars for the new elevation and angle. Tests in the horizontal position and tilted positions areexpected. The present vertical bus bars, and LN2 connections are fixed. We will need to design some sort of clqmped system for the bus bar and will probably just re-pipe the LN2 connection. Disconnect Jan Egedahl’s Magnetic Reconnection Experiment and connect MERIT bus Bars Re-tap transformers to 700v . This is expected to be needed if there is any use of the power supplies between March and August. Collaboration Meeting Reporting, 1 trip, 4 VRVS meetings. These have proven to be a part of the MERIT effort and costing these has largely been ignored in previous efforts. Performance of Mercury Jet TestsThese are expected to begin in August, 2006These tests will be conducted by ORNL with MIT support to operate the Power Supplies, and Cryogenic System. The tests are expected to take about one month with a second month as a contingency. Dave Tracey full time and P. Titus half timeAllow for 18 equivalent full field pulses. This is 12 15T shots plus some number of lesser shots. It is expected that if a nozzle change is needed, Each full field shot takes about 130 liter of LN2 or 2340 liters for the campaignShut Down and Decommissioning of MIT/MERIT Testing AreaPreparation for Shipping to CERNCrates for the MERIT magnet need to be reassembled. Those provided by CVIP will need to be improved to protect bus bars, supports, instrumentation and insulation. Interface with MIT/BNL/ORNL on Shipping and Loan Agreements.Rigging and handling the magnet and Mercury jet system. MIT personnel will operate the crane and fork lift. This took a couple or three technicians when the magnet was offloaded from CVIP.Support at CERN for handling and installation of the MERIT magnet at CERNPrepare user instructions for Magnet and instrumentation. Thiswill be an extraction of information from the earlier test reports, with the addition of the operating manuals for instrumentation. One trip by P. Titus to support installation of the MERIT Magnet power connections and Cryogenic system connections.Appendix APreliminary Plan for Integrated Systems Testing at MIT (Rev.

In this table the duration of the steady-state jet does not include the time for jet ramp up or ramp down, it is only the flat top portion of the jet cycle; the flat top is assumed to be centered at the beam pulse. It is further assumed that the solenoid flat top is also centered at the beam
