The metrology of high power ionization beams faces saturation of conventional detectors. Such devices as ionization chambers or monitor chambers have to evolve to cope with the increasing power of irradiation beams.
Saturation of detectors arises when the numerous charged particles generated in the substrate starts to recombine when drifting towards the collection electrodes. This new technology significantly reduces both the amount and the path of those charged particles throughout the detection process.
The high power beams can be monitored in real time, and in 2D with the quasi transparent sensor, which features high radiation hardness. The overall dynamic of the system ranges from 1 to 1 000 000. Beams up to 1 MW can be characterized.
The composite system: sensor / electronics / versatile control interface is under design. The reference sensor will soon be upgraded with state of the art microelectronics technology. The electronic readout will be tested accordingly. Tests with industrial partners are to be performed before summer.
Recent market studies showed that both industrial processes including cross linking of polymers and radiotherapy evolution, involving high dose rate deliveries, lack devices to monitor their high power ionization beams. The iDORA system is the key element to theirs needs.
