The TEVATRON at  Fermilab provides the highest energy particle collisions in the world.  Two large general-purpose experiments,  CDF and  D0 , are dedicated to the study of these collisions. Harvard is a member of CDF.
The accelerators have been upgraded to produce proton-antiproton collisions at a higher rate. The current run, Run II, started in 2001. CDF is currently taking data. The accelerator division provides continual increases in luminosity.

    People and their work

  • Melissa Franklin (professor)
    The Boss.

  • Andrew ("Andy") Foland (professor)
    Andy prefers red wine, and likes Deep blue but not Yellowish-green brown.

  • Joao Guimaraes (post-doc) da Costa
    I'm not doing anything, please fire me.
    I want to discover New Physics.

  • Lester Miller (post-doc)
    top cross section in W+jets, with SLT (soft lepton tag), also SRC (Silicon Readout Controller)

  • Alexey Ershov (post-doc)
    I'm not doing anything, please fire me.
    (rumor is that he works on beamlines, Stage0, and is interested in measuring the top lifetime)

  • Ayana Holloway (gs)
    I'm not doing anything, please fire me.
    (She did build the analog monitors for the COT, work on Stage0, and the SecVtx scale factor, though)

  • Salvatore Rappoccio (gs) ("Sal")
    I am currently working primarily on b-taggging using SecVtx. I am also finishing the upgrade to 2SRC operation at CDF. Plus, now I am starting to work on the ttbar cross section.

  • Ingyin Zaw (gs)
    I'm working on the CMX and Silicon dE/dx.

  • Daniel Sherman (gs)
    I'd put PrimeVtx and SecVTX Scale Factor for me. And that's generous.

  • John Paul Chou (gs)
    I'm working on the SLT tagger with Lester. I'm also looking for exotic hadrons with Andy. I like long walks on the beach. Turn-offs include ROOT, France, and the culmination of these two: Rene Brun.

    The increase in instantaneous luminosity required many   CDF detector upgrades.
    Harvard has contributed to the R&D and commissioning, and continues to be involved in the maintenance of the SVX, COT, and CMX.

    Detectors

  • SVX
    people:Andrew Foland, Lester Miller, Salvatore Rapoccio
    involvement: SRC (silicon readout controller), alignment, 2SRC upgrade (in progress)

  • COT (password protected)
    people: Melissa Franklin, Ayana Holloway, Joao Guimaraes da Costa
    involvement: field sheets, pressure monitoring, analog readout

  • CMX (link outdated, but informative)
    people: Ingyin Zaw
    involvement: installation/commisioning of CMX miniskirts and keystones (in progress)
