METHOD OF DETECTING PARTICLES USING DRIFT TUBE-BASED DETECTORS Russian patent published in 2014 - IPC G01T1/18 

FIELD: physics.

SUBSTANCE: method of detecting particles using drift tube-based detectors includes measuring coordinates of charged particles, characterised by that it includes first recording the time of arrival of signals t₁ and t₂ from two ends of drift tubes with length L on the leading edge of said signals, and using the value of the time interval Δt=t₁-t₂ to determine the longitudinal coordinate of the avalanching point using the expression ΔL=±V×Δt/2, where V is the propagation speed of the wave on the anode, and ΔL is the distance of the avalanching point from the centre of the anode, and simultaneously determining radial coordinates of a particle in two drift tubes correlated on the passage thereof by varying the time intervals between signals therefrom based on a calibration relationship between drift time and the coordinate.

EFFECT: simultaneous determination of radial and longitudinal coordinates of a charged particle.
