Bergoz

Bergoz Instrumentation develops and manufactures current transformers, current transducers, current monitoring devices and electronic instrumentation for current measurement and elementary particle beams diagnostics, non-destructively. Bergoz instruments are found in applications as diverse as high energy particle accelerators, in research and medicine, on synchrotron radiation light sources, on ion implanters used for materials surface modification, on conformance test benches, to measure partial discharge, corona, isolation breakdown, and many more. Our mission is to create new instruments to answer unsolved challenges in beam instrumentation for particle accelerators. We take an active part in many informal work groups together with those engineers and scientists confronted with these challenges. Our development effort is entirely self-financed, and all our instruments are the result of such collaboration with research institutes worldwide (e.g. Berkeley, Tsukuba, Desy, Cern, Cornell, Kamigori, Los Alamos, Frascati, also Orsay, Slac, Esrf, Aarhus, Riken and Brookhaven). We specialize in ultra-low-noise analog electronics design in the DC...3GHz range. We combine this with knowledge of cobalt-based amorphous magnetic alloys annealing processes for response up to 2GHz and very low Barkhausen noise. Exceptional performance is always expected from our circuits. Signal-to-noise ratio 140dB and linearity 11 octaves are usual demands. Our Saint-Genis Pouilly workshop is well equipped with production machinery and test instruments. This allows us to manufacture and test almost everything in-house. Quality control is extremely strict and largely automated. We preserve indefinitely all construction parameters of every instrument we make, and we can re-calibrate or repair any instrument, even those we made 20 years ago. Our standards and calibration functions are integrated into our production process and our instruments are checked and re-calibrated at frequent intervals against primary standard transfer instruments.
