abstract = {{The TIARA AVF cyclotron provides a He beam for production of At-211 as one of many beam applications. The production rate of At-211 increases with the energy of the He beam, but contamination of Po-210 produced by radioactive decay of At-210, which is generated by the energy of above 29 MeV, must be prevented for medical applications. Therefore, the energy of the He beam must be precisely measured and controlled. A time-of-flight beam energy monitor in the straight beamline from the cyclotron was installed to measure the beam energy in real time. The beam energy was arbitrarily controlled within a range of about 1% by adjusting the cyclotron magnetic field and accelerating voltage, which are the possible causes of the beam energy change. Using this control, we investigated the rate of formation of At-211 and At-210 as the beam energy was varied. As a result, we confirmed the energy generating At-210 and both production rates increased with the energy of the He beam.}},
