The term 'Cyclotron Target' is composed of four words: ATOM (4 letters), ION (3 letters), Ions (4 letters), and Ernest (6 letters). An ATOM is the smallest particle of an element that can exist, and is composed of protons, neutrons, and electrons. An ION is an ATOM or molecule that has gained or lost one or more electrons, giving it a net positive or negative charge. Ions are formed when atoms gain or lose electrons in order to become more stable. Ernest is a reference to Ernest Lawrence, who invented the cyclotron in 1931. The cyclotron is a type of particle accelerator which uses a magnetic field to accelerate charged particles, such as ions, to high speeds. The target of the cyclotron is the material that the particles collide with, which can be anything from a thin foil to a solid block.
