In this episode of Micro Journeys, host Daniel Marrujo travels to the NASA Space Radiation Laboratory (NSRL) to explore one of the only facilities in the country capable of simulating deep-space radiation conditions on Earth. Marrujo sits down with Trevor Olsen, a nuclear engineer and physicist who has worked at the facility for over seven years, to break down how NSRL bombards electronic components with high-energy, heavy ions to prepare them for use in space, national security, and commercial applications.
The conversation dives into the mechanics behind the facility’s synchrotron, where a chaotic, naturally occurring beam must be precisely shaped using a series of dipole, quadrupole, and octupole electromagnets. Olsen walks through how the beam evolves from an unpredictable circular shape into the controlled square form required for testing, and how engineers manage magnet strength and RF cavities throughout the acceleration cycle to keep the beam confined and on target.
The solution lies in real-time control: thousands of dynamic systems work simultaneously to deliver a precisely tuned beam, at the exact ion type and energy level requested, ensuring every test replicates space conditions with scientific accuracy.
