Exploring Space Technology: The Legacy of the Lewis Cyclotron Facility
Key Ideas
- The Lewis Cyclotron Facility, operational since 1957, played a crucial role in research on radiation effects for nuclear vehicles, solar cells, and space power systems.
- Researchers at the facility discovered that cadmium sulfide thin-film solar cells encapsulated in polyethylene film were resistant to proton irradiation, a breakthrough for space applications.
- Studies at the cyclotron also focused on the effect of radiation on liquid hydrogen, particularly in the context of nuclear rockets, providing valuable insights for future space missions.
- The facility's contributions to understanding radiation damage and space technology have left a positive legacy in the field of space exploration and solar power systems.
The Lewis Cyclotron Facility, established in 1957, shifted its research focus from atomic aircraft to space technology following the launch of Sputnik by the Soviet Union. Researchers at the facility conducted studies on radiation effects on materials for nuclear vehicles, solar cells, and space power systems. By using the cyclotron, they were able to determine that cadmium sulfide thin-film solar cells encapsulated in polyethylene film were resistant to proton irradiation, making them suitable for long-duration space missions. Additionally, the facility investigated the impact of radiation on liquid hydrogen, essential for nuclear rockets, and found that the expected ortho to para conversion due to radiation did not occur as anticipated. These findings were crucial for understanding the behavior of hydrogen fuel in extreme conditions. The studies conducted at the Lewis Cyclotron Facility have significantly contributed to the development of space technology, particularly in the areas of solar power systems and nuclear propulsion. The facility's legacy continues to inspire advancements in space exploration and energy efficiency.
