When a magnetic bottle is deformed repeatedly by an adiabatic process shown in Fig. 1, some of charged particles are lost their kinetic energy. By the use of this process charged particles are injected into.a magnetic bottle. Without consideration of other processes, for example, a collision process, charged particles are injected one after another by this process as long as adiabatic approximations are valid. Moreover, charged particles in a magnetic bottle can be accelerated by the reverse process.
