A small quartz fiber calorimeter prototype with copper absorber has be
en assembled and tested at ITEP as a first test of a ''0 degree'' comp
onent of the RD-40 R&D program. Calibration and monitoring of each tow
er response was performed using the positions of single photoelectron
peaks as well as the response to minimum ionizing particles incident a
t an angle of 45 degrees. The response of the prototype to 4 GeV elect
rons as a function of beam angle with respect to the quartz fibers was
studied in the range from 0 degrees to 90 degrees. The test results a
re compared to the GEANT based Monte Carlo (MC) simulations.
