TL;DR: Progress is presented on the development of the technology to provide reliable high throughput inner wall pellet fuelling, pellet ELM pacing with high frequency small pellets and disruption mitigation with gas jets and shattered pellets.

TL;DR: In this article, deuterium pellets have been injected into plasmas in the DIII-D tokamak from the inner wall, top, and outer midplane port locations to investigate fuelling efficiency, mass deposition and interaction with edge localized modes (ELMs).

TL;DR: The material plasma exposure experiment (MPEX) is a newly proposed steady state linear plasma device designed to deliver the necessary plasma heat flux to a target for testing, including the capability to expose a priori neutron-damaged material samples to those plasmas as discussed by the authors.

TL;DR: In this paper, a pipe-gun pellet injector with a cryogenic refrigerator was fitted with a relatively large barrel (16.5mm bore), and D2 and Ne pellets were made and were accelerated to speeds of ~ 600 and 300 m/s, respectively.

TL;DR: In this paper, an experimental mock-up of the proposed ITER curved guide tube for inside wall pellet launch was set up in the lab and tested with nominal 5.3mm D 2 pellets.
