Bergoz Vibrating Wire Monitor, VWM
The VWM is based on the wire resonant frequency dependence on its tension, itself dependent on its temperature. A positive feedback oscillator excites the wire oscillations at this resonant frequency. Particles penetrating the wire heat it, change its tension and therefore its resonant frequency. Vibrating wire sensors have been applied to electron, proton, ion and photon beams. VWM can be used for neutron beams too.
The Vibrating Wire Monitor system components include: Fixed or moving wire sensor; Twisted pair cable to Front-end electronics; Front-end electronics box, each supports 2 wires; Electronics to chassis cable, up to 50 meters; and Chassis can support up to 8 Front-end electronics.
Features
