Stable Periodic Signal Generator (clock) based on Beta Particle Emissions

詳細技術說明
A device and method for generating a stable periodic signal were developed for use as a frequency or time keeping signal source.
*Abstract

This invention is for a device and method for generating a stable periodic signal for use as a frequency or time keeping signal source. Emissions from a radioactive thin film are detected and used to generate a periodic signal based on the radioisotope's decay rate. To improve stability, a dead-time controlling attenuator responds to the radioactive emission detector signal and attenuates it for a selected dead-time interval. The insensitivity of beta emissions to ambient conditions makes the device stable under most conditions.

 

Potential Applications

  • Precise time or frequency reference for sensors, cellular telephones, communication devices

 

Advantages

  • Low cost
  • Long life
  • Simple, robust design
  • Minimal-power consumption
  • Unaffected by ambient conditions such as temperature
  • Uses Ni-63, a safe radioisotope
    • Predictable rate-of-decay can be systematically corrected
