TL;DR: In this article, a crystal-based beam extraction technique was proposed to extract multi-GeV electron beams in a parasitic mode from electron synchrotrons worldwide, which is able to supply fixed-target experiments by intense high-quality monoenergetic electron beams.
Abstract: We propose to apply crystal-based beam extraction technique to extract multi-GeV electron beams in a parasitic mode from electron synchrotrons worldwide. This technique will be able to supply fixed-target experiments by intense high-quality monoenergetic electron beams. We design the experimental setup to extract 6 GeV electron beam from the DESY II Booster Synchrotron. We simulate the process of extraction as well as optimize crystal geometry. We discuss the influence of radiation energy losses on the extraction process. Finally, we claim that the multi-turn electron beam extraction efficiency may reach 16 %.

TL;DR: In this paper, an end-of-substructure-card prototype for the ATLAS Inner Tracker strip tracker is used to estimate its material distribution with high spatial resolution using the reconstructed scattering angles and hit positions of high energy electron tracks traversing an object under investigation.
Abstract: The simulation and analysis of High Energy Physics experiments require a realistic simulation of the detector material and its distribution. The challenge is to describe all active and passive parts of large scale detectors like ATLAS in terms of their size, position and material composition. The common method for estimating the radiation length by weighing individual components, adding up their contributions and averaging the resulting material distribution over extended structures provides a good general estimate, but can deviate significantly from the material actually present. A method has been developed to assess its material distribution with high spatial resolution using the reconstructed scattering angles and hit positions of high energy electron tracks traversing an object under investigation. The study presented here shows measurements for an extended structure with a highly inhomogeneous material distribution. The structure under investigation is an End-of-Substructure-card prototype designed for the ATLAS Inner Tracker strip tracker -- a PCB populated with components of a large range of material budgets and sizes. The measurements presented here summarise requirements for data samples and reconstructed electron tracks for reliable image reconstruction of large scale, inhomogeneous samples, choices of pixel sizes compared to the size of features under investigation as well as a bremsstrahlung correction for high material densities and thicknesses.

TL;DR: The SiD Detector is one of two detector designs for the future International Linear Collider (ILC) that were validated in 2012 and features a compact, cost-constrained design for precision Higgs and other measurements, and sensitivity to a wide range of possible new phenomena as discussed by the authors.
Abstract: The SiD Detector is one of two detector designs for the future International Linear Collider (ILC) that were validated in 2012 SiD features a compact, cost-constrained design for precision Higgs and other measurements, and sensitivity to a wide range of possible new phenomena. A robust silicon vertex and tracking system, combined with a five Tesla central solenoidal field, provides excellent momentum resolution. The highly granular calorimeter system is optimized for Particle Flow application to achieve very good jet energy resolution over a wide range of energies. With a potential construction date of the ILC moving closer, it is now the time to review the design and technology decision that have been made during the DBD phase and reconsider them in the light of the recent technological advances. For each area of SiD development R&D topics and opportunities for participation will be discussed.
