LASY: LAser manipulations made eaSY

Using realistic laser profiles for simulations of laser-plasma interaction is critical to reproduce experimental measurements, but the interface between experiments and simulations can be challenging. Similarly, start-to-end simulations with different codes may require error-prone manipulations to convert between different representations of a laser pulse. In this work, we propose LASY, an open-source Python library to simplify these workflows. Developed through an international collaboration between experimental, theoretical and computational physicists, LASY can be used to initialize a laser profile from an experimental measurement, from a simulation, or from analytics, manipulate it, and write it into a file in compliance with the openPMD standard. This profile can then be used as an input of a simulation code

Design Initiative for a 10 TeV pCM Wakefield Collider

This document outlines a community-driven Design Study for a 10 TeV pCM Wakefield Accelerator Collider. The 2020 ESPP Report emphasized the need for Advanced Accelerator R\&D, and the 2023 P5 Report calls for the ``delivery of an end-to-end design concept, including cost scales, with self-consistent parameters throughout." This Design Study leverages recent experimental and theoretical progress resulting from a global R\&D program in order to deliver a unified, 10 TeV Wakefield Collider concept. Wakefield Accelerators provide ultra-high accelerating gradients which enables an upgrade path that will extend the reach of Linear Colliders beyond the electroweak scale. Here, we describe the organization of the Design Study including timeline and deliverables, and we detail the requirements and challenges on the path to a 10 TeV Wakefield Collider

A plasma accelerator driven by an industrial Yb:YAG laser at kHz repetition rate

High average power, kHz laser-plasma acceleration is an emerging technique which could supply few MeV, few femtosecond electron bunches with high average current. Here we present exciting experimental results, drawing the path towards the first electron acceleration driven by an industrial Yb:YAG laser at multi-kHz repetition rate.KHz lasers usually deliver few mJ pulses and, hence, compressing the output pulse duration down to the few-cycle regime is essential in order to efficiently drive plasma waves. We report on record post-compression results, where 10mJ, 1.2ps pulses have been compressed to below 10fs, with 70% efficiency. The interaction of these pulses with an high density nitrogen plasma shows exciting evidence of plasma waves being driven.Furthermore, Particle-In-Cell simulations including the real pulse, the retrieved plasma density and the measured spot size prove the potential of such pulses to accelerate electrons in the few MeV regime
