Positrons are the same in the sense that they don't penetrate far into the skin, but when they collide with a particle in your body, gamma rays are generated by matter-antimatter annihilation. And gamma rays are very bad for you, indeed, as they have both high energy and can easily pass through your tissues.
The initial beam diameter (4 mm) was reduced to 80 Î¼m. However, this spatial resolution is not high enough. To focus beam more, a small positron source should be fabricated. In this work, we developed a positron microbeam by a small source, a solid neon moderator, magnetic lenses and a SEM optics. In addition, a beam pulsing system was also developed which allows the positron annihilation lifetime spectroscopy (PALS) measurement.
