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

Transverse profile and position monitor
Fixed multi-wire sensor or moving sensor
For beams: Photon from infrared to keV, Electron, proton from keV to GeV and Neutrons
Output is digital value proportional to number of particles hitting the wire
Data communication is via USB
Example software is provided

Applications

Electron beam scan in vacuum: 20MeV electrons. 70pA wire-intercepted current resolution.
Proton beam scan in vacuum: 15GeV protons. 3pA wire-intercepted current resolution.
Photon beam scan in vacuum: 14keV photon mean energy. 1.4E+7 ph/sec wire-intercepted flux resolution.
Photon beam scan in air: 100keV photon mean energy. 3E+13 ph/sec wire-intercepted flux resolution.
