Measurement of wiretension in drift tubes by resonance in a magnetic field
Description
Wiretension in drift chambers is commonly measured by observation of resonance frequency. In drift tubes, where the wire cannot be seen by eye, a vibration of the wire has to be detected in other ways. The method described here uses a simple bridge circuit for measuring the change in dc-resistance of the resonating wire. The decrease of the resistance (0.3%) is due to self-cooling (0.50C) by convection when the wire starts swinging. (orig.)
