About

New Products Design

Every year, we take part in 4-5 international conferences on particle accelerators beam instrumentation, in Europe, the U.S. and Asia. Our purpose is to identify new projects that pose unresolved instrumentation challenges. We form informal work groups with those who encounter these challenges.  Close contact is maintained. This happens way before the actual development of a new instrument starts. New instruments take a long time to come to life.  They are born from the needs of future users. When the required instruments appear feasible, we get to work. Our development effort is self-financed. In this process, we have collaborated with more than 50 research institutes worldwide, like: Berkeley, KEK, Desy, Cern, Cornell, SPring-8, Los Alamos, Frascati, also Orsay, Slac, Esrf, Aarhus, Riken and Brookhaven. 

When the prototypes are ready, we ship them for testing by their prospective users.
Their feedback helps us improve the products.  Test results are published at an appropriate conference.
It brings us new customers.  Development of a new product typically takes 6 years.

How we do it

We specialize in ultra-low-noise analog electronics design in DC...3GHz range and high-performance magnetic alloys. We acquired an intimate knowledge of cobalt-based amorphous and iron-based nanocrystalline materials. We use the best available instruments from manufacturers like Keysight/Agilent, LeCroy, Anritsu, Tektronix, Rohde-Schwarz, Ifr-Marconi. We simulate circuits, design schematics, and draw layouts with computer-based tools. Exceptional performance is always expected from our instruments. Signal-to-noise ratio > 140dB and linearity over 11 octaves are not unusual achievements.

Those performances cannot be simulated by computer. They require many successive generations of prototypes. Magnetic sensors also demand extreme performance from magnetic alloys, response up to 2GHz and very low Barkhausen noise. Development of a new instrument requires 2-3 years of work in addition to 2-3 years for initial concept.

 

Particle accelerators are used primarily :
- For fundamental physics research as carried for instance at CERN, Fermilab, GSI, Brookhaven, DESY, KEK, GANIL, RIKEN.
- For materials study by photon or neutron beams, as done at all synchrotron light sources, free electron lasers and spallation neutron sources.
- For cancer therapy by protons, carbon ions and neutron-boron capture in 110 medical centers operating or under construction in the World.
New types of particles accelerators are constantly proposed.  
Among them, very promising laser-plasma accelerators are developed by a large number of institutes.
New types of accelerators often require new instrumentation.

Manufacturing

Our Saint Genis Pouilly workshop is well equipped with production machinery and instruments. Everything is manufactured and tested in-house, except printed circuits boards etching and ultra-high vacuum parts. Our quality control is extremely strict and largely automated to avoid human errors.  It is ISO-9001 (2008) certified. All manufacturing parameters of every instrument ever made are preserved indefinitely. We can recalibrate or repair any instrument, even those we made >25 years ago.

Calibration

Standards and calibration functions are integrated at every step of the production process. Our instruments are recalibrated against primary standard transfer instruments, as often as needed.
