Design considerations for the use of laser-plasma accelerators for advanced space radiation studies [PDF]

, 2012
We present design considerations for the use of laser-plasma accelerators for mimicking space radiation and testing space-grade electronics. This novel application takes advantage of the inherent ability of laser-plasma accelerators to produce particle ...

Heat transfer properties of laser assisted plasma processing [PDF]

, 2012
Laser assisted plasma processing (LAPP) is a novel extension to already established Reactive Atom Plasma (RAP) processing for atmospheric pressure dry chemical etching of silicon based materials; this is mainly applied for optical uses.

Pepper-pot emittance measurement of laser-plasma wakefield accelerated electrons [PDF]

, 2009
The transverse emittance is an important parameter governing the brightness of an electron beam. Here we present the first pepper-pot measurement of the transverse emittance for a mono-energetic electron beam from a laser-plasma wakefield accelerator ...

Laser Plasma Accelerators [PDF]

Physics of Plasmas, 2012
This review article highlights the tremendous evolution of the research on laser plasma accelerators which has, in record time, led to the production of high quality electron beams at the GeV level, using compact laser systems. I will describe the path we followed to explore different injection schemes and I will present the most significant ...

Controlling the characteristics of injected and accelerated electron bunch in corrugated plasma channel by temporally asymmetric laser pulses

Scientific Reports, 2022
In laser-driven plasma wakefield accelerators, the accelerating electric field is orders of magnitude stronger than in conventional radio-frequency particle accelerators, but the dephasing between the ultrarelativistic electron bunch and the wakefield ...

Development of low-coherence high-power laser drivers for inertial confinement fusion

Matter and Radiation at Extremes, 2020
The use of low-coherence light is expected to be one of the effective ways to suppress or even eliminate the laser–plasma instabilities that arise in attempts to achieve inertial confinement fusion.

An all-sputtered photovoltaic ultraviolet photodetector based on co-doped CuCrO2 and Al-doped ZnO heterojunction

Scientific Reports, 2021
We propose and fabricate a heterojunction between Al-doped ZnO and (Mg, N)-doped CuCrO2 thin films using the sputtering deposition method. These materials possess wide bandgap that makes them transparent in the visible light but excellent UV-absorbers ...
