  1. SMTF Controls Dennis J. Nicklaus Fermilab ICALEPCS 2005

  2. SMTF SMTF = Superconducting radio frequency Module Test Facility

  3. SMTF • Main Goal: Develop U.S. Capabilities in high gradient and high Q superconducting accelerating structure in support of the International Linear Collider. • Proton Driver, RIA, 4th Generation Light Source and other accelerator projects • Expanding upon existing SCRF expertise at: Argonne, Cornell, Fermilab Jefferson Lab, MSU

  4. SMTF Collaboration Collaborating Institutions and their representative • Argonne National Laboratory: Kwang-Je Kim • Brookhaven National Laboratory: Ilan Ben-Zvi • Center of Advanced Technology, India: Vinod Sahni (More institutions have been asked to join) • Cornell University: Hasan Padamsee • DESY: Deiter Trines • Fermi National Accelerator Laboratory: Robert Kephart • INFN, Pisa : Giorgio Belletini • INFN, Frascati: Sergio Bertolucci • INFN, Milano: Carlo Pagani • Illinois Institute of Technology: Chris White • KEK: Nobu Toge • Lawrence Berkeley National Laboratory: John Byrd • Los Alamos National Laboratory: J. Patrick Kelley • Massachusetts Institute of Technology: Townsend Zwart • Michigan State University: Terry Grimm • Northern Illinois University: Court Bohn • Oak Ridge National Laboratory: Stuart Henderson • Stanford Linear Accelerator Center: Chris Adolphsen • Thomas Jefferson National Accelerator Facility: Swapan Chattopadhaya • University of Pennsylvania: Nigel Lockyer • University of Rochester: Adrian Melissions

  5. SMTF Controls People • Many contributors: Ron Rechenmacher, Sharon Lackey, Ruben Carcagno, Geoff Savage, Vladimir Sirotenko, Vince Pavlicek, Gustavo Cancelo, Mike Kucera, Fritz Bartlett, and Luciano Piccoli under the direction of Helen Edwards and Paul Czarapata.

  6. SMTF Goals • Provisional goal is to have three U.S. and one European 1.3 GHz ILC cryomodules under test, with beam, by the end of 2009

  7. SMTF Fermilab Siting • Initial tests at Fermilab’s Meson lab • Fall 2005 test of single 1.3 GHz 9-cell TESLA cavity (RF, cryo, no beam).

  8. Fermilab Siting • Move the NICADD (Fermilab A0) photoinjector to Fermi’s New Muon building to use as a test beamline • Produces low emittance, high-intensity electron beam

  9. Controls Definition • Convened panel of experts in early 2005 • Debated merits of ACNET, EPICS, and DOOCs • Recommendation: All are suitable. Pick one control system while recognizing there is much EPICS expertise with the SMTF collaboration • Recognition of reality: short term scheduled goals imply a mix for now.

  10. Important Notice • SMTF Controls != ILC anything.

  11. Current Status and Work • Cryogenics • LLRF • Modulator • Klystron Interlocks • Timing

  12. LLRF Controls • DESY-provided Simcon FPGA-based LLRF controller (single-cavity) with initial MATLAB interface and in-progress DOOCS interface running on VME-based Sparc SBC. • DESY-provided ADC and DAC cards with DOOCS interfaces.

  13. Cryo Controls • Replicate and enhance ACNET-based control over PLCs • EPICS EDM displays to Epics OPC interface to OPC Server to PLCs.

  14. Modulator • PC/104 board with digital and analog I/O running eCos OS • In use for other Tevatron controls at Fermilab • EPICS ported to eCos for use at SMTF

  15. Klystron Interlocks • Short term re-using IRM-based system (IRM parameter pages) from previous experiment at Fermilab. • Replace with custom VME cards controlled by conventional EPICS VME IOC.

  16. Timing • Industry Pack IP-177 8-channel delay timer • Common design in many applications at Fermilab and elsewhere

  17. Conclusions • As expected, using a mix of several control systems for the short term (IRM, EPICS, DOOCS, Matlab). Converging? • DOOCS contributions from DESY collaborators are integral parts of the system. • Lots of efforts in understanding DOOCS and EPICS at Fermilab.
