Abstract
Photomultiplier tubes for converting photons converted from radiant rays by a scintillator into electric signals are severally connected to preamplifiers. The outputs of the preamplifiers are connected to weighting resistors through nonlinear amplifying circuits. The nonlinear amplifying circuit nonlinearly amplifies the output signals of each two adjacent preamplifiers in accordance with the correlation between the output signals of the preamplifiers, thereby producing two output signals.
