ATHENA detector proposal - a totally hermetic electron nucleus apparatus proposed for IP6 at the Electron-Ion Collider

ATHENA has been designed as a general purpose detector capable of delivering the full scientific scope of the Electron-Ion Collider. Careful technology choices provide fine tracking and momentum resolution, high performance electromagnetic and hadronic calorimetry, hadron identification over a wide kinematic range, and near-complete hermeticity.This article describes the detector design and its expected performance in the most relevant physics channels. It includes an evaluation of detector technology choices, the technical challenges to realizing the detector and the R&D required to meet those challenges

DEVELOPING AN EUROPEAN QUALITY ASSESSMENT TOOL FOR SCHOOLS

Purpose \u2013 The purpose of the research was to develop a simple self-evaluation model and tool that would be based on the preferences of improvement areas of all the stakeholder groups and that also would be possible to use in all European countries. Design/methodology/approach \u2013 The methodology starts with a survey to three school levels (primary, secondary, and vocationa) in seven EU countries, in which the opinions of important factors and their related importance are surveyed of the relevant stakeholder groups (school workers, pupil associations, parents, municipal education authorities, next higher school level, or employers). Total N of responses of stakeholder groups was 126. The relative importances are then built into a DEXi model with weightings generated from the responses, and \ufb01nally a self-assessment tool that uses the DEXi structure developed for the use of the schools in their quality improvement

Precision Studies of QCD in the Low Energy Domain of the EIC

103 pages,47 figuresThe manuscript focuses on the high impact science of the EIC with objective to identify a portion of the science program for QCD precision studies that requires or greatly benefits from high luminosity and low center-of-mass energies. The science topics include (1) Generalized Parton Distributions, 3D imagining and mechanical properties of the nucleon (2) mass and spin of the nucleon (3) Momentum dependence of the nucleon in semi-inclusive deep inelastic scattering (4) Exotic meson spectroscopy (5) Science highlights of nuclei (6) Precision studies of Lattice QCD in the EIC era (7) Science of far-forward particle detection (8) Radiative effects and corrections (9) Artificial Intelligence (10) EIC interaction regions for high impact science program with discovery potential. This paper documents the scientific basis for supporting such a program and helps to define the path toward the realization of the second EIC interaction region
