  • Abstract
    A low noise JFET has been built with a small diode diffused in the gate circuit. For these initial experiments the chips were bonded to an available 4-lead ceramic insulated header. Both dc and pulsed reset methods are possible. The present experiments with a dc reset method indicate that the device when optimized should give, at low count rates, similar resolution to opto-electronic feedback. An output count rate of 20,000 c/s at 6 keV adds 150 eV of noise.
