Pellet injection on TPE-RX

Pellet injection has been operated in TPE-RX. The pellet is injected into the TPE-RX from a horizontal port. It has been shown that the pellet is deflected in the plasma current direction at plasma edge and goes towards plasma center. It is considered that the fast electrons ablate the pellet and the pellet trajectory is deflected as expected. Pellet injection was performed in standard and PPCD discharges at Ip=300 kA. The density increases due to the pellet injection is more than two times that of standard plasma. The significant density increase in PPCD discharges is maintained for a long period.
