Einstein's general theory of relativity from 1915 1 remains the most successful description of
gravitation. From the 1919 solar eclipse 2 to the observation of gravitational waves 3, the …

Abstract At the historic Shelter Island Conference on the Foundations of Quantum
Mechanics in 1947, Willis Lamb reported an unexpected feature in the fine structure of …

The positron, the antiparticle of the electron, predicted by Dirac in 1931 and discovered by
Anderson in 1933, plays a key role in many scientific and everyday endeavours. Notably, the …

Abstract In 1906, Theodore Lyman discovered his eponymous series of transitions in the
extreme-ultraviolet region of the atomic hydrogen spectrum,. The patterns in the hydrogen …

Positrons (ie, antielectrons) find use in a wide variety of applications, and antiprotons are
required for the formation and study of antihydrogen. Available sources of these antiparticles …

Magnetized nonneutral plasma composed of electrons or positrons couples to the local
microwave environment via cyclotron radiation. The equilibrium plasma temperature …

We publish three Roadmaps on photonic, electronic and atomic collision physics in order to
celebrate the 60th anniversary of the ICPEAC conference. In Roadmap II we focus on …

This document provides detailed information on the status of Advanced and Novel
Accelerators techniques and describes the steps that need to be envisaged for their …

Methods for reducing the radius, temperature and space charge of a non-neutral plasma are
usually reported for conditions which approximate an ideal Penning Malmberg trap. Here …

Currently, the world's only source of low-energy antiprotons is the AD/ELENA facility located
at CERN. To date, all precision measurements on single antiprotons have been conducted …
