Interactions Between Charged Particles in a Magnetic Field
The present theory for the penetration of charged particles through matter rests on the fundamental work by Bohr, Bethe and Bloch. Due to the progress in the ac- lerationand detectionofparticles since the earlyyearsof the last centuryan incre- ing rangeofapplicationshas emerged,bothin fundamentalphysicsbut also in ?elds like medical radiology,materials science, nuclear ?ssion and fusion technology and many others. These developments require a detailed and quantitative knowledge about the processes occuring during the passage of charged particles through m- ter. A comprehensive overview on the present status of the theory of stopping of heavy ions in matter has, e. g., been presented in recent monographsby Sigmund. However, in recent decades considerable interest has been directed towards applications in which strong magnetic ?elds play a dominant role. Then the - clotron radius of the target electrons is the smallest relevant length scale and their cyclotronperiod the smallest time scale of the problem. While the ?elds occuringin magnetic con?nement fusion devices are still marginal in this sense, stronger ?elds are employed to guide the electrons in the cooling sections of particle storage rings and even more so for the deceleration of heavy ions and antiprotons in traps. In the rest frame of the beams the cooling/decelerationprocessmay be viewed as the st- pingof ionsin an electronplasma. Exceptforrecombination,changesin the internal structure are not so important in these applications. The emphasis of this book lies therefore on the interaction of ions with a magnetized electron plasma.
