Unique instruments, developed over 40 years, designed to last forever, no obsolescence.
Non-intercepting Beam Instrumentation
Our non-intercepting measurement systems allow a characterization of low current particle beams without disturbing beam quality.
This exceptional strength is recognized throughout the particle accelerator landscape. 99% of the world’s high-energy particle accelerators of all technologies use our instruments: Sources, Linacs, Microtrons, Cyclotrons, Synchrotrons, Laser-plasma…
The performance of our instruments is also increasingly appreciated by medical accelerators for proton, carbon ions and neutron-boron capture cancer therapy.
Our product portfolio is adapted to measured
- Current DC & AC
- Charge of single or repetitive pulses
- Beam position
- Longitudinal profile
- Transverse profile and halo
- Beam loss
Passive current transformers whose output signal can be directly visualized and processed by, for example, oscilloscopes.
Analog RF Electronics
Analog electronics adapted to treat signals coming from beam position pick-ups, for example buttons, strip lines or shoeboxes, installed on the beam line.
Sensor and Electronics Combinations
Combining a sensor with electronics allows to extend available solutions towards higher precision, for example sub-pC pulse charge, and to enable measurements of otherwise inaccessible beam parameters, for example current of DC beams.
In-air model: sensor potted in a toroidal copper casing
Installed over the vacuum chamber. Requires installation of a “gap” to prevent the wall current from flowing through the sensor aperture.
The “gap” can be a brazed ceramic ring or an organic material O-ring depending on the vacuum requirements.
Typical installations include bellows, a wall current bypass and an electromagnetic shield enclosing the sensor completely.
In-flange model: sensor embedded in a pair of flanges
Easily mounted on the beam line.
In-flange model includes a vacuum-brazed ceramic gap and does not require bellows, wall current bypass or electromagnetic shield.
Ultra High Vacuum compatible down to 10-11 mbar
Different aperture sizes are available
In-vacuum model: sensor embedded in a stainless-steel box
Specially designed to be installed inside big vacuum chambers as used, for example by laser plasma accelerators.
Vacuum compatible down to 10-7 mbar.
