Measurement of beam intensity of electrically charged particles in superconductive accelerators using SQM

This paper is aimed at theoretical aspects of the application of superconducting quantum magnetometers in measurement of beam intensity of electrically charged particles in superconductive accelerators. The parameters of antenna system, which picks up the magnetic field induced by unidirectional component of the accelerated particles current, are examined. From the analysis it follows that for accelerators with a beam trajectory radius of the order of 10 super(1) m the spectral sensitivity limit is of the order of (10 super(2) - 10 super(3)) elementary particles/(cycle Hz super( is equivalent )).
