Who is this Mark fellow, and why does he have so much equipment? There are two branches on the Mark family tree at Stanford University. Mark is the name that has been given to several generations of both accelerators and detectors created and used at HEPL and here at SLAC.  The accelerators were all built on campus at HEPL, and were progenitors of the two-mile accelerator that was built at SLAC. The detectors have all (so far) been built at SLAC.

Mark I 1947 Electrons first successfully accelerated using a waveguide accelerator
Mark II 1949 First successful operation
Mark III 1949 Construction begins
  1950 First successful operation
  1963-64 Disassembled and re-built with new accelerator sections
Mark IV 1954 Support received from AEC to build as a test-bed for the two-mile accelerator
  1964 Dismantled

For more detail on Mark and other Stanford accelerators, see the "Linear Accelerators Constructed at Stanford," table from Mary Clarke's inventory of Edward Ginzton's papers held by the Stanford University Archives.
