Stable Periodic Signal Generator (clock) based on Beta Particle Emissions
- 详细技术说明
- 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

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
