FIRST RESULTS OF DUST INJECTION IN T-10 PLASMA

First results of T-10 injection experiments of the carbon dust particles with 2-10 μm diameter and 40-300 m/s velocity are presented. Different scenarios of the dust injection were tested. The dust particles ablation was studied. An approach for determination of a dust particle penetration length was developed. Measured penetration depths (3-7 cm) are compared with the simulation by the ablation model. The μm range of the separate dust particle diameters derived from the ablation data was close to sizes of the dust injected assuming that an acceleration of the separate particle is similar to the large carbon pellet in the pellet injector. PACS: 52.55.-s, 52.40.-w
