The G0 project in Hall C at Thomas Jefferson National Accelerator
Facility will use an array of 256 scintillator detectors in an effort
to determine the strangeness content, or G0. The team is hopeful that
knowing the G0 constant will help provide a solution to the spin
crisis for the proton. The scintillators, however, must have surfaces
that are reflective to an optical quality. They are being polished,
but it is a difficult task to be sure if the surface is perfect. For
this purpose, a device must be built to automate the task of scanning
the surface for missed imperfections and scratches.
