The results of a pulse power generator driving an axial virtual cathode oscillator are being presented in this paper as a source of high power microwave (HPM) radiations. The electron beam generator is also modified to attain the intense X-ray burst. The pulse power generator used for these applications is common and is having 10 ohms as its characteristic impedance with 50nS of pulse width. The peak...
Preliminary experimental results of an axially extracted virtual cathode oscillator (vircator) built on the low impedance pulsed electron beam accelerator AMBICA-600 is reported. The AMBICA-600 pulsed power system mainly comprises of a coaxial waterline charged from single turn Tesla transformer. Waterline has impedance of ~5Ω and generates pulse width of ~60ns. The generated pulsed high power microwave...
Transient electroluminescence is widely used to obtain the effective mobility of carriers in single layer polymer light emitting diodes (PLEDs). We monitor the shape of the pulse mode electroluminescence (EL) of PLED with two different active layers viz. a new polymer derived from Bispyrrole (AVPV) and poly [2-methoxy-5-(2'-ethylhexyloxy)-p-phenylene vinylene] (MEH-PPV). We show that the occurrence...
