METHOD OF DETERMINING COORDINATES OF CHARGED PARTICLES Russian patent published in 2010 - IPC G01T1/00 

FIELD: physics.

SUBSTANCE: invention relates to methods for determining spatial position and energy of relativistic particles, streams of ionising radiation and optical radiation. The method of determining coordinates of charged particles involves placing a recording matrix made from N-N regularly arranged elements on the path of charged particles. Each element is made from three types of luminophors which are distinguished by wavelength of radiation maximum, where each i^th element (where i=1, 2, 3…N) with coordinates x_i, y_i corresponds to a single concentration ratio a/b/c of three luminophors, corresponding to coordinates of the i^th element in the matrix and recorded in the memory of the recording device. Luminescent emission arising from charged particles falling onto the matrix is directed to three photodetectors with selective coefficients of spectral response n_a n_b, n_c, matched with wavelength of radiation maximum of corresponding luminophors and recorded in the memory of the recording device. Output signals S₁ S₂, S₃ of the photodetectors are transmitted to the recording device where they are summed up, normalised to the value of the obtained sum, and values S_1norm, S_2norm, S_3norm are obtained, and values k₁=S_1norm/n_a k₂=S_2norm/n_b, k₃=S_3norm/n_c are determined in the recording device. The ratio of obtained values k₁/k₂/k₃ is compared with concentration ratios of three luminophors ai/bi/ci recorded in the recording device. Coordinates of the charged particles x, y are determined from the coordinate of that i^th element the concentration ratio ai/bi/ci of which coincides with ratio of the obtained values k₁/k₂/k₃.

EFFECT: new method of determining coordinates of charged particles.
