MOM Report October 9- Now Linda R. Coney UCR
October 15thRunning • Target • Beamline Magnets • Detectors? • Could not turn on • HV supply in hall off • HV supply crashed • Target DAQ • DAQ? • Could not run w/o detectors on • Was NOT working • Caused major problem Saturday
October 18th Running Dosimeter arrays: Single dosimeter mounted on the exit window of the decay solenoid; Array of dosimeters on the inside the DSA north wall; Array of dosimeters on the inside of the DSA west wall; Array of dosimeters on the upstream surface of the fixed radiation-shield wall.
Goal1: Study beam loss and particle rate as fxn of target dip depth Goal2: Install dosimeters in DSA and Hall Results:October 18thRunning 19:20 Target actuations start. Time Loss setting GVA1 GVA2 Counts 19:34 1 5786 1231 12045 19:41 2 6468 1087 10243 19:47 3 11755 1244 10550 19:58 3 (repeat) 10451 1156 10146 20:03 4 13808 3607 10201 20:07 5 16508 1494 10393 20:13 6 22085 1870 11875
Issues: October 18th Running • DAQ not working when start running • GVA2 disconnected – • had to debug/discover/reconnect/power up • Target delay adjustment – caused target dipping to stop • Had to debug – 1.5 hr delay
October 19thRunning • Goal: Measure change in activation of synchrotron with MICE target operating at MS/128 and producing beam loss at the 200 mV level for a period of sixteen hours. • Dosimeter arrays installed • “Pre-run” rad survey done • Turned on magnets, target, detectors, target DAQ, DAQ
Results: October 19th Running • New Target DAQ info • ISIS beam intensity, Total Beam Loss • Sector 7, Sector 8
Results: October 19th Running • New Target DAQ info • ISIS beam intensity, Total Beam Loss • Sector 7, Sector 8
Results: October 19th Running • NO issues getting started/running!! • Startup ~ 1 hour • Took data all day – 14 hours • Many shifters • Detectors and DAQ running • scanned beam momentum in steps of 20 MeV/c from 100 MeV/c – 400 MeV/c • 19, 658 target actuations
General ToDo List • ELOG running and being used* • Install dosimeter arrays in/around DSA and hall – done, will stay until user run begins • Establish routine monitoring points in hall with Charlie East – pending • Need local time server in MLCR – JSG • Need dedicated Windows machine in MLCR in order to change target delay – KL sorted out • Target DAQ integrated into DAQ – pending
General ToDo List Cont’d • Decay Solenoid Fridge – Linde worked on fridge to fix recent problems • fit the pressure reducer and clean the gas after the blockage experienced in the last cool down • May still be leak - investigating • North wall finished by Nov 14 • Dust/dirt in hall on/near power supplies still an issue • need professional cleaning • PPS – installing yellow cage doors next to MLCR, mezzanines
Shutdown ToDo List • Open up Decay Solenoid and install more diagnostics - done • Fix Q4,Q5, Q6 water leaks - done • Moveable beam stop in place/test – done & working • Concrete floor block started – finished • FNAL beam monitors • Small one rebuilt, noise problem fixed, reinstalled behind DS, and running • almost done • Large one - pending • Reinstall GVA1, GVA2 – done • Recover from power outage – done • Commissioning runs on CKOV – ongoing (Dan?)
Documentation • Need for standard procedural and for troubleshooting • Target • Beamline magnets • Decay solenoid/fridge • Detectors • Target DAQ • DAQ • ELOG - works
Other Useful Changes • Phones in MICE corral in R76 dial internationally • New MICE visitors webpage • Maps, instructions for first visit, safety training information, travel and transport info, local restaurant and lodging info • Shipped 6 VLSB, 7 AFEIIt spare boards to FNAL (Terry comment) • New MICE digital camera • Facilitate trouble shooting/documentation/recording actions • Start overall contact list ** • MICE van CAN be parked overnight at Cosener’s House • Have established procedure for obtaining permission to drive van • Must be more formal than previously thought
Future Commissioning Needs • Standardize MOM handoff • Wrote document for transition from my term to Dan • MOM handoff information • Hall search and secure procedure • Daily walkthrough procedure • Prepare for running procedure • ToDo list as of end of current MOM term • List of contact people for ongoing, high priority projects • Should be edited/added to as needed • Documentation • MUST document everything given few experts and many shifters • MUST use/read ELOG Exercise equipment regularly – whether taking beam data or not
Future Commissioning Needs • Exercise equipment regularly – whether taking beam data or not • Formalize run training like safety training? • “certified” to turn on magnets, dip target, run DAQ • Review previous run periods • How improve efficiency & productivity • What went wrong – how avoid next time • Like M&M for med school (morbidity & mortality) • Run review panel?
