Abstract A method of stabilizing operation of a hybrid spark chamber is disclosed. The method is applied to a self-triggering hybrid spark chamber of the gas-flow type including a spark chamber portion and a proportional chamber portion, and utilizes a high speed discharge circuit for the proportional chamber portion, the high speed discharge circuit being so constructed that upon generation of a precedent spark in the spark chamber portion by electrons produced by radiation and multipled in the proportional chamber portion the discharge circuit is simultaneously operated in response to the spark so as to rapidly lower an electric field intensity of the proportional chamber portion, thereby preventing the generation in the proportional chamber of any induced spark.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
143 words
A method of stabilizing the operation of a gas-flow type self-triggering hybrid spark chamber having a spark chamber portion and a proportional chamber portion, and in which electrons produced by radiation are multiplied in the proportional chamber portion and generate sparks in the spark chamber portion, said method comprising connecting a high speed discharge circuit to the proportional chamber portion and utilizing the discharge of said circuit to lower the electric field intensity of said proportional chamber portion below a threshold value at the above which it is solely possible for a spark to be induced in said proportional chamber portion by a spark generated in said spark chamber portion, said discharge being initiated in response to each spark generated in said spark chamber portion and before the instant at which a surrounding induced spark in said proportional chamber portion would otherwise occur.
Claim 2
Independent Claim

A method of stabilizing the operation of a gas-flow type self-triggering hybrid spark chamber having a spark chamber portion and a proportional chamber portion, and in which electrons produced by radiation are multiplied in the proportional chamber portion and generate sparks in the spark chamber portion, said method comprising connecting a high speed discharge circuit to the proportional chamber portion and utilizing the discharge of said circuit to lower the electric field intensity of said proportional chamber portion below a threshold value at the above which it is solely possible for a spark to be induced in said proportional chamber portion by a spark generated in said spark chamber portion, said discharge being initiated in response to each spark generated in said spark chamber portion and before the instant at which a surrounding induced spark in said proportional chamber portion would otherwise occur.
Claim 3
Dependent Claim
