Shock tensiometer for multiwire chambers

This paper describes the operation and circuit of a tensometer based on a new method of determining the frequency of natural oscillations of multiwire chambers filaments by means of shock excitation of oscillations that provide sufficient accuracy under the indicated measurement conditions. The device is suitable for measuring the filament tension of chambers of various designs, is simple to operate, and provides high productivity. The range of tension measurement of 0.5-70 g for gold-plated tungsten filaments 20 microm in diameter and 60 cm long is established with the device.
