TL;DR: In this paper, the authors presented two different designs of robust, easily manufactured metamaterial-based films of subwavelength thickness capable of full absorption of incident terahertz radiation at certain frequencies.

TL;DR: Rosenzweig et al. as discussed by the authors proposed the UC-XFEL, which is a very compact XFEL with high gradient acceleration and x-ray free electron laser-based bunching.

TL;DR: In this article, a multi-meter long collinear dielectric wakefield accelerator that achieves a highly efficient transfer of the drive bunch energy to the wakefields and to the witness bunch is considered.

TL;DR: In this paper, the authors review the current state-of-the-art in understanding the phenomena of ultra-high vacuum radio-frequency breakdown in accelerating structures and the efforts to improve stable operation of the structures at accelerating gradients above 100 MV/m.

TL;DR: In this paper, the authors describe the architecture and predicted performance of a novel light source, which promises photon production per pulse of a few percent of existing XFEL sources, when combined with inverse free electron laser-based bunching techniques can produce multikA beams with unprecedented beam quality, quantified by 50 nm-rad normalized emittances.
