Penning Ion Source Under Development

PhD student Nicolas Savard is conducting research into a penning source design intended for creating α particles to produce isotopes such as 211At and 117mSn for use in radioimmunotherapy. During his research he will also be testing the viability of heavier positive ions such as Ar9+ and Kr9+ which can be considered as proxy particles for important ions used in semiconductor implantation. Other experiments on the source will involve reversing polarity to test its capability of producing Hand D- . For the project, D-Pace has designed a 270 mm diameter magnet producing a confined dipole magnetic field of 0.4 to 1.1 Tesla. Initial simulations illustrate good resolution of He++ (inner trajectory) and He+ (outer trajectory), refer to Figure 1.

The second simulation (Figure 2) illustrates the trajectory plots of Ar9+ and Ar8+ showing that the magnet can also be used to measure heavy ion beams of high-charge state.
