| Abstract: | A new flexible and efficient pellet injector with more barrels is designed for the HL-2A core plasma fueling at higher plasma parameters.The design of the 25-barrel pellet injector based on the G-M cycle refrigerator is introduced in this paper.Components,engineering parameters and structure design are all described.The thermal stresses of main parts are calculated in detail using a 3-dimensional heat transport analysis code.Temperature gradient along the barrel and pellet injection modes are also discussed. |
