ABSTRACT:
A neutron radiation insensitive crystal oscillator. The device includes two crystals with neutron sensitivity coefficients of opposite sign. The crystals may be connected either in parallel or series relationships. The addition of tuning reactances to the circuit permits control of the circuit's overall resonance.
