Chase, R. L.

The mechanical tension in the anode wires of a multiwire proportional chamber must be sufficient to prevent wire displacement due to electrostatic forces between wires but must not exceed the breaking strength of the wires. A technique is described for inferring the tension by measuring the mechanical resonart frequency of the wires. It employs a servomechanism which uses the small capacitance change of the selected wire to tune a variable frequency oscillator to the mechanical resonance. Since it is not necessary to observe the wires visually, the technique is applicable to closed chambers in inaccessible locations.
