Cyclotron

This element, considered to be radioactive and classified as a metal, is artificially produced by bombarding atoms of americium-243—an isotope of the element Americium (Am)—with ions of a rare isotope calcium-48 using a device called a cyclotron.

The two cyclotrons achieve their biological effects by focusing charged particles on the tumor. However, the mechanisms differ.

We do not examine the 6 hours surrounding perikron as the ion cyclotron waves in this region have already been extensively discussed [Leisner et al., 2006]. Perikron was close to 2100 on 24 December and the inbound pass cuts through the dayside magnetosphere.
