“…Several experiments have attempted to use laser-produced X-ray sources for this application, with relatively good success. A 1.2 TW Ti:Sapphire laser was focused onto a 0.5 mm Al foil to produce bremsstrahlung X-rays that were used to detect acrylic, Copper and lead blocks inside an Aluminum container [216]. In this experiment, the energy of the backscattered X-rays was within 70-200 keV and the object was placed about 1 meter from the source.…”

Laser-wakefield accelerators (LWFAs) were proposed more than three decades ago, and while they promise to deliver compact, high energy particle accelerators, they will also provide the scientific community with novel light sources. In a LWFA, where an intense laser pulse focused onto a plasma forms an electromagnetic wave in its wake, electrons can be trapped and are now routinely accelerated to GeV energies. From terahertz radiation to gamma-rays, this article reviews light sources from relativistic electrons produced by LWFAs, and discusses their potential applications. Betatron motion, Compton scattering and undulators respectively produce X-rays or gamma-rays by oscillating relativistic electrons in the wakefield behind the laser pulse, a counterpropagating laser field, or a magnetic undulator. Other LWFA-based light sources include bremsstrahlung and terahertz radiation. We first evaluate the performance of each of these light sources, and compare them with more conventional approaches, including radio frequency accelerators or other laser-driven sources. We have then identified applications, which we discuss in details, in a broad range of fields: medical and biological applications, military, defense and industrial applications, and condensed matter and high energy density science.

National highway road security is challenging with increase of terrorist attacks across the world. The shipment of payload materials and illegal weapons in containers and even transport cars is a significant component to deliberate in modern days. This paper focused on three stage toll gate security system to automate the security level at targeted toll gates on road highways. X-ray scanning mechanism is proposed at stage 1 to scan the hidden objects. Back scattered X-ray method is applied to improve the scan process. Capacitive stretch sensor technology is proposed to weigh the moving vehicle. The capacitive sensitivity is increased with three electrode layers. Radio frequency technology is proposed for toll management system. Global System for mobile communication is implanted for communicate with toll amount information, Overload state of the vehicle, weapons and explosive information to the pre defined destination locations. The proposed methodology is reliable to safeguard the human life and to alert the security agencies from the terrorist movements in road highways.
