| Abstract: | An eleven-pass, two-wavelength interferometer for density measurements within the ionisation relaxation region of rare-gas shock waves has been developed. The minimum detectable electron density is 1·1014 cm?3. A method to calculate the electron temperature profile across the relaxation region from the measured density profiles is described. |
