We present a new technique of direct measurement of wire tensions in wire c
hambers. A specially designed circuit plucks the wire using the Lorentz for
ce and measures the frequency of damped transverse oscillations of the wire
. The technique avoids the usual time-consuming necessity of tuning circuit
parameter to a resonance, it allows a fast and convenient determination of
tensions and is straightforward to implement. (C) 1999 Elsevier Science B.
