Abstract
We have developed spectrographs to measure the electron temperature in gas‐filled targets and low‐density foams, and find it to nominally fall in the 2–4‐keV range. The instrument we designed, built, and fielded can simultaneously record the Ti Heα and Cr Heα line emission. After compensating for the instrumental response, we can estimate the electron temperature from this line ratio to within ±15%.Keywords
