The generation of energetic photons in the context of inverse Compton scattering has attracted a great lot of interest from many contemporary scientific fields. Radiobiology, materials physics, and medicine are some of the current fields where inverse Compton scattering is used. In this study, the applications of nonlinear inverse Compton scattering will be demonstrated and illustrated based on laser plasma interaction. This paper introduces and highlights the current advancement in this area, which is a crucial component of quantum physics, as well as the potential uses in the future depending on additional study. Thorough explanations are demonstrated and talked about the uses of inverse Compton scattering. To highlight our thoughts on present developments and potential future advancements in the field, we have extended and expanded on the theme using simulations and experimental data. These results pave a path to generate and shed light on guiding further state-of-art proposals for High flux X/gamma ray generation.

“…In the field of ultra-high intensity ( > 10 18 W/cm 2 ) laser-plasma interactions, high-energy photon (x-rays and γ-rays) production has become of great interest for its impact on plasma dynamics (e.g., effects of radiation reaction on particles [1][2][3][4]), for fundamental studies (e.g., investigation of quantum-electrodynamics (QED) in strong fields [5] and plasmas [6,7]), and for several potential applications. Some of these are plasma diagnostics [8], interrogation of nuclear materials [9], radiography [10], tomography [11], and imaging [12] for industrial and medical purposes, as well as photo-nuclear spectroscopy [13,14].…”

Non-linear inverse Compton scattering (NICS) is of significance in laser-plasma physics and for application-relevant laser-driven photon sources. Given this interest, we investigated this synchrotron-like photon emission in a promising configuration achieved when an ultra-intense laser pulse interacts with a double-layer target (DLT). Numerical simulations with two-dimensional particle-in-cell codes and analytical estimates are used for this purpose. The properties of NICS are shown to be governed by the processes characterizing laser interaction with the near-critical and solid layers composing the DLT. In particular, electron acceleration, laser focusing in the low-density layer, and pulse reflection on the solid layer determine the radiated power, the emitted spectrum, and the angular properties of emitted photons. Analytical estimates, supported by simulations, show that quantum effects are relevant at laser intensities as small as ∼1021 W/cm2 Target and laser parameters affect the NICS competition with bremsstrahlung and the conversion efficiency and average energy of emitted photons. Therefore, DLT properties could be exploited to tune and enhance photon emission in experiments and future applications.

“…LPAs have previously been used to drive x-ray sources for industrial imaging [16]. There have groups that have used an LPA-ICS source for radiography [17][18] and tomography [19]. In the LPA-ICS source tomography work, the source xray energy was about 75 keV.…”

Nondestructive characterization is often carried out on dense materials and objects, such as cargo, and high atomic number advanced manufactured, and traditionally manufactured parts and assemblies. These often require high-energy x-rays, exceeding 1 MeV, and sub-millimeter spatial resolution for characterization. Current high-energy x-ray systems offer limited flexibility in tuning the x-ray energy and spatial resolution. Current x-ray sources include bremsstrahlung tube heads that operate from 10 to 600 kV and accelerators that operate from 2 to 15 MV. The MV systems have spatial resolution on the order of a millimeter which limits the features that can be observed. An alternative approach is to use an inverse Compton scattering (ICS) x-ray source with a linear plasma accelerator (LPA). This is a powerful emerging technology that can provide tunable keV to MeV, quasi-monoenergetic x-rays, and a focal spot size on the order of a micrometer. Our research seeks to answer the question: can ICS x-ray sources fundamentally change the way x-ray non-destructive characterization (NDC) is carried out on these challenging parts, assemblies, and cargo? We performed the first CT scans using the Berkeley Lab Laser Accelerator Hundred TeraWatt (BELLA HTW) ICS x-ray source. We scanned parts of tungsten carbide and steel. Our reconstructed images, although they have artifacts, demonstrate the potential of the LPA-ICS source to image challenging objects. We will discuss the system used, results, lessons learned and paths forward.
