Possible Digital Circuit Able to Recognize Magnetic Monopoles Crossing a Thick Scintillator Counter

摘要

A CAMAC digital circuit to identify slow magnetic monopoles crossing a thick scintillator counter, and to reject events of any other kind, taking advantage of the different time configurations of the corresponding signals, is proposed. The circuit identifies a magnetic monopole event when it recognizes that the output signal from a photomultiplier width reproducing discriminator signal is continuous and long enough. The continuity is selected by a suitable preset threshold on a time-gap comparator.
