Transparent position-sensitive particle detector

Particle detector (2) comprising:

• electron multiplication means (4) that are capable of producing a cluster of electrons under the impact of each particle, and
• a layer of a light emitting material (6) that is capable of emitting a light pulse by interaction with the electron cluster, characterized in that this layer also allows this cluster to pass through it and that the detector also comprises electron detection means (8) capable of collecting this cluster of electrons and providing an electrical signal to determine the particle impact moment, and which are sensitive to the position and capable of supplying information about the positions of impacts for each moment thus determined, these detection means also being transparent to light pulses so that the positions of impacts may be determined by localizing light pulses emitted by the layer of material, and these positions may be correlated with the moments determined by means of the electron detection means.
