The discovery of chirped pulse amplification has led to great improvements in laser technology, enabling energetic beams be compressed durations tens femtoseconds and focused a few micrometers. Protons with energies MeV can accelerated using, for instance, target normal sheath acceleration on secondary targets. Under such conditions, nuclear reactions occur, the production radioisotopes suitable medical application. use high-repetition lasers produce isotopes is competitive conventional...
The present study was undertaken in the Scarcity Zone of Western Maharashtra with objective examining inputoutput relationship and resource use efficiency milk production. revealed that concentrates have positive significant influence on production from both buffaloes crossbred cows area. Concentrates were underutilized for milking cows. Dairy farmers should put more efforts efficient utilisation to increase There is a need technical guidance particularly regarding scientific feeds fodder...
Abstract The interaction of focused high power laser beam with solid targets leads to acceleration charged particles among other by non-linear effects in the plasma. In this experiment, hot electrons are characterized from sub-nanosecond and kilo-joule class pulse thin metal foil (Cu, Ta, Ti, Sn, Pb). energy distribution functions were measured angularly resolved multichannel electron spectrometer. temperatures observed range 30 80 keV for intensities between ${\sim}10^{15}$ $3 \times...
This article provides an up-to-date overview of the problems associated with detection hot electrons escaping from laser-produced plasma and corresponding return current flowing ground to target, which neutralises positive charge occurring on target due escaped electrons. In addition, holder system acts as antenna emitting electromagnetic pulse (EMP), is powered by target. If amount generated equal carried away electrons, measurement makes it possible determine this charge, thus also number...
In this Letter, we report the possibility of generating intense, highly energetic proton beams using terawatt, sub-nanosecond class laser system by irradiating modified cavity pressure acceleration-type targets. approach, main source few-mega electron volt protons is thermonuclear deuterium–deuterium reaction; therefore, energy spectrum accelerated particles and their number not as strongly related to intensity (laser pulse duration in particular) case most common ion acceleration mechanism,...
The interaction of high-power laser pulses with undercritical foams produced by different techniques but the same average density is studied at PALS facility. spatial–temporal evolution X-ray emission observed using an streak camera, electron and ion temperatures are measured spectroscopy, hot-electron production characterized monochromatic imaging. Transmission a femtosecond probe pulse through in near far fields. In spite large differences pore size foam structure, velocity ionization...
Abstract Electron acceleration by an Inverse Free Laser (IFEL) pulse in the presence of static magnetic field has been studied. With high intensity laser and plasma interaction, wakefield can be excited which further utilized to accelerate injected electrons. Highly energetic interacting with excites a relativistic electrons are trapped. The provides additional resonance trapped electrons, energy is transferred effectively thereby, resulting highly higher gain.
