Apparatus for the microcollimation of particles, detector and particle detection process, process for the manufacture and use of said microcollimating apparatus

Particle detector incorporating a particle converter permitting the production of charged particles, an array of microcollimators, each having a size of about 1 micrometer, drilled in random manner, but oriented in parallel, in an insulating sheet with a thickness between a few micrometers and several millimeters and a charged particle detector.

A process for the detection of particles comprising:

• providing a microcollimating apparatus comprising an array of microholes with a size of approximately 1 micrometer, drilled in a random manner, but oriented in parallel, in an insulating sheet with a thickness between a few micrometers and several millimeters, and placing the microcollimating apparatus between a layer for converting the particle into electrically charged fragments and a charged particle detector.

Use of an array of microcollimators for separating particles having different incidences, wherein the microcollimators are each constituted by an array of microholes with a size of approximately 1 micrometer, drilled in a random manner, but oriented in parallel, in an insulating sheet with a thickness between a few micrometers and several millimeters.

Use of an array of microcollimators for attenuating an incident beam wherein the microcollimators are each constituted by an array of microholes with a size of approximately 1 micrometer, drilled in a random manner, but oriented in parallel, in an insulating sheet with a thickness between a few micrometers and several millimeters.
