Abstract
A method and device for measuring the magnetic rigidity of penetrating charged particles uses an elongated transparent ionizable medium, surrounded by a reflective interface, extending along a helical path around a longitudinal axis. A magnet applies a magnetic field to the medium in a direction along the longitudinal axis. A single luminosity proportional photon detector is operationally associated with the medium and adapted to generate signals indicative of the number of photons transiting the medium. A controller is adapted to receive the signals and calculate a penetration depth of the ionizing particle through the medium based on the number of photons transiting the medium and a magnetic rigidity of the charged particle based upon the penetration depth.

A device for measuring the magnetic rigidity of penetrating charged particles, said device comprising:
- an elongate transparent ionizable medium extending along a helical path around a longitudinal axis, said medium being surrounded by a reflective interface;
- a magnet adapted to apply a magnetic field to said medium in a direction along said longitudinal axis;
- a single luminosity proportional photon detector operationally associated with said medium and adapted to generate signals indicative of a number of photons transiting said medium;
- a controller adapted to receive said signals and calculate a penetration depth of said ionizing particle through said medium based upon said number of photons transiting said medium and a magnetic rigidity of said charged particle based upon said penetration depth.
A method for measuring the magnetic rigidity of penetrating charged particles, said method comprising:
- providing an elongate transparent ionizable medium extending along a helical path around a longitudinal axis, said medium being surrounded by a reflective interface;
- applying a magnetic field to said medium in a direction along said longitudinal axis;
- providing a single luminosity proportional photon detector operationally associated with said medium and adapted to generate signals indicative of a number of photons transiting said medium;
- providing a controller adapted to receive said signals;
- allowing an ionizing particle to pass through said medium, thereby creating photons therein, said photons transiting said medium;
- counting the number of photons transiting said medium using only said single photon detector, said single photon detector generating said signals indicative of said number of photons transiting said medium;
- calculating a penetration depth of said ionizing particle through said medium based upon said number of photons transiting said medium using said controller;
- and
- calculating, in the absence of temporal coincidence, a magnetic rigidity of said charged particle based upon said penetration depth using said controller.
