A telescope used to search for massive and/or fractionally charged particles in the cosmic radiation is described. The telescope uses plastic scintillators (for ionization and time-of-flight measurements), wide gap spark chambers (to fix particle trajectories) and lead/iron absorbers (for range measurements). Timing and ionization measurements are recorded using a fast oscilloscope. Measurements are recorded for slow particles (0.2 c<0.55 c) only. The accuracies of the measurements are such that charge measurements deduced from the speed and ionization measurements are accurate to 0.05 e (one s.d.). Finally, the construction, calibration and operation of the telescope are described.
