Claim 1
Independent Claim
100 words
IN A NUCLEAR PARTICLE DETECTOR, A GAP-FILLED SPARK CHAMBER HOUSING AN ANODE AND A CATHODE ADAPTED TO BE ENERGIZED BY A D-C POTENTIAL, MEANS CONNECTED TO SAID ANODE FOR AMPLIFYING ELECTRON PULSES CAUSED AS NUCLEAR PARTICLES PASS THROUGH SAID CHAMBER AND IONIZE THE GAS THEREIN, GENERATOR MEANS RESPONSIVE TO SUCH AN AMPLIFIED PULSE FOR APPLYING A HIGH VOLTAGE PULSE TO SAID CATHODE TO CAUSE A SPARK IN SAID CHAMBER ALONG THE PATH OF A PASSING NUCLEAR PARTICLE, AND CIRCUIT MEANS ALSO RESPONSIVE TO AN AMPLIFIED PULSE FOR BLOCKING THE AMPLIFIER MEANS DURING A PREDETERMINED DEAD TIME OF THE SPARK CHAMBER.
