Light emission from a titanium vacuum arc using Fizeau interferometry with parallel detection.
The lineshape of light emission from a titanium vacuum arc was studied using a Fizeau interferometer coupled with an optical multichannel analyzer (OMA). A viewing geometry normal to the cathode surface was employed. Temperatures of ~3 x 10(5) K and ~3.5 x 10(4) K were obtained for titanium ions and titanium atoms present in the cathode spot, respectively. In light of results from previous work, a case is made for the latter temperature being the actual heavy species temperature in the cathode spot.
