The production of 9C beam in the secondary beam line of the HIMAC facility and its potential application in cancer therapy Original Research Article

The emitted particles from a β-delayed particle decay beam must enhance biological effects in the region of interest and such a radioactive ion beam may be useful in cancer treatment. To test this therapeutic purpose of β-delayed particle decay beams, 9C beams were produced in the secondary beam line at HIMAC for the first time. The thickness of production target and degrader to yield a 9C beam with higher production rate and purity was optimized and the momentum distribution of the produced 9C beam under the optimal condition was measured. For upcoming radiobiological experiments, a uniform irradiation field for the produced 9C beam was made by means of wobbling magnets.
