On the weekend run, we observed coincidences between the
two HRS spectrometers in H(e,e'p) elastic scattering at 2.4 GeV.
The TOF resolution online without any path-length corrections
was 6 nsec (FWHM) with a small satellite peak due to scintillator
offsets. The momentum setting of first the electron arm and then
the hadron arm were adjusted to move the peak over the focal plane
and determine the coincidence efficiency. The scan was repeated
with the sieve slit on the electron arm. We adjusted the spectro-
meters for proton knockout from oxygen, and took about 35K events
(10% coincidences) before a water leak in Hall C forced an end
to the run. The accelerator availability was about 40%.
