Abstract Text:
Many aspects of plasma research involve understanding dynamic plasma formation processes, approaches to plasma equilibria, magnetic reconnection, and plasma instabilities or wall interactions. In ICC experiments not only are many of these (ideal & resistive MHD, or kinetic) timescales quite rapid, but due to power and current drive limitations, the plasma lifetimes themselves are quite short. In the past we have used single (or few) frame imaging cameras in the visible to soft x-ray regime to glean insights into the plasma behavior, assuming repeatability and then using multiple shots to develop a time history. With a new Hadland Ultra 24 intensified framing camera, (24 frames, 200 Million images/second framing rate, 12-bit dynamic range, at 1024x1024 pixels per frame) procured with ARRA funding in FY2010, we will be able to image a wide range of plasma phenomena in a single shot. Plans for using this system in with visible or soft x-ray photons (as appropriate), on a variety of fusion experiments (TCS-U, HIT-II, ZAP, LDX, PLX, FRXL, FRCHX, NSTX) will be discussed. This work is supported by the Office of Fusion Energy Sciences, and DOE/LANL contract DE-AC52-06NA25396.

A5 and E4. Is there a diagnostics grouping?
