Abstract :
Hybrid Photon Detectors (HPD) detect light via photocathodes and accelerate the emitted photoelectrons by an electric field towards silicon PIN-anodes, where they are absorbed and generate electronic signals. We have developed two specific types of HPDs: (1)
photomultiplier tubes for photon counting and gamma spectroscopy;
g silicon pixel array tubes for optoelectronic cameras.
aper will illustrate the main achievements, which we obtained in the last years, and will describe and discuss our present main R&D efforts, in particular, in the bio-medical imaging field. © 2002 Elsevier Science B.V. All rights reserved.
