Measurements of carbon and tungsten erosion/deposition in the DIII-D divertor

  • 1. Sandia National Labs., Livermore, CA (United States)
  • 2. General Atomics, San Diego, CA (United States)

Description

Net erosion/deposition rates of carbon and tungsten were measured at the outer strike point of the divertor plasma on the floor of the DIII-D tokamak during deuterium H-mode operation at a peak power deposition of about 40 W/cm2. For carbon, net erosion rates of up to 4 nm/s were found. For a tungsten film, no appreciable erosion was detected. However, measurements of deposited tungsten on adjacent carbon surfaces indicated a net W erosion rate of 0.06 nm/s
