Abstract: The 60Hz high-frequency cryogenic pellet preparation system was successfully developed with the collaboration of PELIN Laboratory Ltd. It was designed to produce cylindrical cryogenic pellets with diameter of 1.0mm and adjustable length of 1.0mm~1.3mm. The pellets can be injected into the plasma at a frequency within 60Hz with an adjustable speed at 100m/s~300m/s. The engineering commissioning shows that the preparation system meets the design requirements of preparing pellets, and can run stably and reliably. It provides a basis for the physical research of pellet injection on the HL-2A/2M tokamak.

Key words: high-frequency, cryogenic pellet injection, engineering commissioning
