Abstract
The linear accelerator principle as used in the Sloan and Lawrence positive ion accelerator1 has received a new stimulus from the advent of radar magnetrons giving high peak powers under pulse operation at short wave-lengths. These new techniques are particularly suitable for the acceleration of electrons, since their velocity may easily be made comparable, even at injection, with the velocity of propagation of electromagnetic waves. It therefore becomes practicable to accelerate electrons continuously by carrying them in tight bunches around a stable position in a travelling radio-frequency wave.
