Thomas Jefferson National Accelerator Facility - Visit the Technology Review Committee Website
A compact radiation tolerant and magnetic field immune radiation detector including a detector front-end having an electro-optical coupling detector (EOCD) capable of operating within high radiation and strong magnetic fields and a back-end that can be located a substantial distance from the front-end and thus away from the high radiation and strong magnetic fields The back-end of the detector includes a multi-wavelength light source and at least one optical receiver. The EOCD in the front-end simultaneously modulates and multiplexes pulses from light sensors by transferring them to the optical domain and then transmitting them through a single-mode fiber to an optical receiver in the back-end. During the fiber transmission, relative phase, amplitude and timing information among multiplexed signals is maintained. High-index silica planar AWGs and electro-optical conversion modulators minimize the effects of radiation damage and ASICs contribute to the compactness of the front-end.
