Abstract
A pulsed discharge through plastic capillaries is investigated using spectroscopic and cinematographic techniques. In the wavelength region 2600 - 5600 Å the emission was nearly that of a black body of 30 000 °K lasting for nearly 150 μsec; therefore the light source can be used as a suitable radiation-standard in μsec-spectroscopy. The optical thickness is measured and compared with calculations of continuum-intensity. Estimates of pressure and electron density lead to values of 150 atm max. and 2·1019 cm-3 respectively. Also the plasma jet protruding from the capillary is investigated.
