27. 27 BROOKHAVEN SCIENCE ASSOCIATES Transport Line Controls Two clusters in order: the development cluster and production cluster. The source code for application is developed and maintained on the development cluster. Only the executable image and support file are moved to the production cluster. The software environment is mainly built (not limited) around Python, PyQt for the GUI. The machine information is displayed using CSS (BOY). Virtual machine: ready for LtB (including LtD1 and LtD2) transport line. The source code is developed and tested in the virtual machine. The virtual machine status can be read/set with command caget/caput. Channel finder: ready for LtB transport line, in Python and CSS environment. Twiss server: under development with Tracy and Elegant. Online Twiss server provides Twiss parameters, 6*6 transfer matrix and orbit. Offline Twiss server function is more diverse, depending on the applications. The IRMIS database: under development. High level applications: mostly under the specifications stage. The emittance measurement source code is under test with virtual machine. Machine display panel: under development. Courtesy of G. Wang, B. Dalesio, G. Shen, K. Shroff, J. Hu

28. 28 BROOKHAVEN SCIENCE ASSOCIATES Booster-to-Storage Ring transport line Booster-to-Storage ring transport line is complete at final design stage We are beginning to populate the drawing with the actual element layouts watching for interferences in the past months we were focusing on LtB TL as needed first for the linac commissioning Diagnostics transport line Required for booster commissioning

29. 29 BROOKHAVEN SCIENCE ASSOCIATES Risks and their mitigation At this point we consider the following injector subsystems as presenting risks that: may impact on the system performance may cause delays in the project schedule For these subsystems risk mitigation plans are in place SubsystemRisk mitigation plan Performance of linac gun modulator (pulser) LFE test program at NSLS-II (SDL) to characterize the pulser/gun If the pulser development failed: Substituting current version of the pulser by the existing design with lower performance In-house pulser development Booster dipoles field quality Cross check of magnetic models at NSLS-II We modified design of mag measurement stand proposed by BINP and providing required hardware Senior consultant (former SLS) is coming on board

30. 30 BROOKHAVEN SCIENCE ASSOCIATES Risks and their mitigation SubsystemRisk mitigation plan Delays with TL magnets delivery Subset of the LtB TL magnets required for the linac commissioning is expedited Program on magnetic measurements of the TL magnets at BNL is under discussion Senior consultant from SLAC is on board for biweekly visits of the vendor factory SR pulsed magnet cost and schedule Pulsed Magnet lab is being equipped for pulsed magnet tests at BNL Alternative plans of the pulsed magnet development are in place Delays due to foreign procurement regulations and export control issues We are in close collaboration with the vendor’s management and procurement department Export Control issues being addressed by NSLS-II project team and BNL legal office

31. 31 BROOKHAVEN SCIENCE ASSOCIATES Conclusion Great progress made On Schedule, On Budget and Staffing In Place Risks well understood, mitigation plan in place FY11 and beyond thoroughly planed Full speed ahead for early completion

33. 33 BROOKHAVEN SCIENCE ASSOCIATES BACK-UP

34. 34 BROOKHAVEN SCIENCE ASSOCIATES Plans for the injector controls Develop the Linac and LtB application first, then the booster, BtS and injection straight line. Divide the injector control into three catalogs: operator panel, procedure execution manager and physics application. The operator panel for transport line displays/sets the magnet power supplies, diagnostics, vacuum, water, interlocks. It has the function of channel finder, alarm, history data browser. LtB operator panel will be ready in Sep. 2011 for hardware test. BtS operator panel will be ready in the of May. 2012. Procedure execution manager : Execute a series of routine machine procedures (such as start-up, shutdown). Provide a graphical interface to permit the user to invoke machine procedures and monitor their execution. It makes the operation automatically and save the operation time. Physics application : for high level application, such as beam emittance measurement. They are developed by individual scientists and tested in the virtual machine first. After it works well in the machine test, someone will assemble and re-organize them so that the software is easy to maintain later. The routine functions: 1) save/compare/restore for saving the snapshots, setpoint, and offsets, comparing the interested machine history data, and restoring part/all of save-set. 2) run control to support access from multiple computers to the hardware control. It permits an application to "register" itself with an EPICS record, thereby preventing the same application from being run. 3) control law provides a generic feedback, such as maintain constant energy and injection trajectory to booster/SR.
