Description
A planar spark counter of 500 μm spark gap was tested with cosmic rays. A time resolution of 134 ps was achieved. The test was carried out for several quenching gas pressures. The best performance was obtained at a gas pressure of 4 atm (2.5 atm of argon and 1.5 atm of the quenching gas). The counter efficiency was about 93%. This low pressure permits easy construction of the counter with a thin pressure vessel. Subsequent measurements using 60Co γ-ray sources gave a discharged area of about 5 mm in diameter. (orig.)
