For over 80 years emissive probes have been used to measure plasma potential and a wide
variety of methods for interpreting probe data now exists. Constructions, heating methods …

A characterization is presented of Mo sources Γ Mo, core Mo content N Mo and their
dependences on the Alcator C-Mod operational regimes. The primary impurity source …

This article provides recommended methods for building, operating, and taking plasma
potential measurements from electron-emitting probes in electric propulsion devices …

Ion cyclotron range of frequency (ICRF) heating is expected to provide auxiliary heating for
ITER and future fusion reactors where high Z metallic plasma facing components (PFCs) are …

In Alcator C-Mod, we have sought to identify ICRF specific impurity sources and estimate the
lifetime of thin, low-Z films in the presence of high power ICRF heating. With ICRF, the …

A novel experiment to investigate single-surface multipactor on a dielectric surface was
developed and tested. The compact apparatus consists of a small brass microwave cavity in …

This paper summarizes highlights of research results from the Alcator C-Mod tokamak
covering the period 2006–2008. Active flow drive, using mode converted ion cyclotron …

A two strap fast wave antenna has been developed which is capable of operating at arbitrary
phasing for any level of plasma loading resistance. Recent advances in the understanding …

The formation and maintenance of an electrostatic potential well by injecting electrons into a
quasispherical cusped magnetic confinement geometry is studied experimentally, as a …

A new probe system consisting of a bias compensation circuit and a CO 2-laser-heated
emissive probe is presented. This system has been verified to have a sufficiently high time …
