IMPROVING THE ACCURACY OF MEASURING THE POSITION OF A PULSED CHARGED-PARTICLE BEAM

A technique for improving the accuracy of measuring the position of ch arged particle beams by means of magnetoinductive sensors is described . The effect is achieved by means of winding a coil on a core accordin g to the cosine density distribution, which does not significantly com plicate the sensor design. This solution can be applied to both ferrom agnetic and air-cores. The fabricated sensors were experimentally test ed with the use of a conductor with a current (a beam simulator). The experiments have shown that when the conductor position changes within 0.85 and 0.77 of the inner radius of the core for the air- and ferrom agnetic-core sensors, respectively, a +/-1% relative measurement error can be reached.
