Fundamental principles of operation of the continuous pellet injector for ITER

Abstract The basic principle of the design and operation of the continuous pellet injector with the rotor transporting unit for ITER is described. The injector will be able to inject continuously hydrogen isotope pellets with the diameter and length 6 mm, velocity (1.2–2.0) km s−1 and repetition rate up to 6 s−1, that meet the requirements for the ITER continuous pellet injector.
