In this work we report what we believe to be the first observation of the third continuum of argon in plasmas, at pressures between 100 and 4000 Torr, created by discharge excitation. This continuum, centered at 188 nm, has been clearly seen not only

Described here is the design and construction of a pulse‐power generator capable of discharging at high repetition rates. It consists of eight triaxial Blumleins stacked in series at one end. These lines are charged in parallel and synchronously co

Recently we reported the development of a prototypical pulsed x-ray generator driven by stacked Blumleins [1] . Eight triaxial Blumleins were stacked in series at one end and synchronously commuted at the other end by a single thyratron. Significant

In this work we report the first observation of the screening effect in large‐area, cold‐cathode diodes. A framing camera was used to observe the formation of emission centers (ECs) on a 200 cm2 velvet emitter. The density of ECs increased as a f

The fluorescence from high-pressure argon plasmas (1-30 bar) has been excited with an intense flash X-ray device. For the first time a spectrum from 110 to 700 nm has been recorded under such conditions. The spectra obtained in the UV-VUV were very s

Efforts to demonstrate the feasibility of a gamma-ray laser scored major advances in 1988 and 1989. Culminating with the discovery of giant pumping resonances below 4 MeV for dumping isomeric populations, priority issues were brought into better focu

Efforts to demonstrate the feasibility of a gamma-ray laser scored major advances in 1987. Culminating with the successes in optically pumping the first of the 29 actual candidate isomers, priority issues were brought into better focus by the lessons

Eight triaxial Blumlein circuits have been stacked in series at one end while being synchronously commuted at the other end with a single hydrogen thyratron. Having no other switching elements, operation has been possible at repetition rates up to 10

Eight triaxial Blumleins have been stacked in series at one end while being synchronously commuted at the other end with a single hydrogen thyratron. Significant voltage gain has been maintained in the stack for periods of the order of 20 ns. Having
