Abstract
An apparatus for monitoring an electrically charged particle pulse includes at least one coil defining an opening therethrough. The coil generates a bipolar signal responsive to the electrically charged particle pulse passing through the opening, and the bipolar signal comprises a first portion having a first polarity and a second portion having a second polarity. Unipolar blocking diode connected to the coil passes the first portion of the bipolar signal having a first polarity and blocks the second portion of the bipolar signal having the second polarity. Monitoring Device connected to the unipolar blocking diode generates an output signal representative of a predetermined characteristic of the particle based upon the first portion of the bipolar signal which is passed by the unipolar blocking diode. In a preferred embodiment, the coil has a toroidal shape and comprises a plurality of windings electrically connected in parallel, and each of these windings comprises a plurality of conductive loops. The apparatus may also comprise a series of coils arranged so as to define a predetermined path for passage of the electrically charged particle through each respective opening of each respective coil.
