Reconstruction of Tungsten (111) and (211) Surfaces Induced by Carbon and Oxygen

Scanning tunneling microscopy is used to obtain images of reconstructed W(111) and W(211) surfaces. The reconstruction is induced by submonolayer coverages of carbon and oxygen

Oxygen-Induced Thermal Faceting of Pd Nanosized Crystals

The oxygen-induced faceting of [111] and [100] oriented Pd nanosized crystals (“tips”) was studied by field ion microscopy (FIM). Annealing at temperatures of 500 K in the presence of submonolayer amounts of oxygen caused major reconstruction to occur. Regions of the {100} plane broke up into small {100}, {112}, and {012} facets. In addition, only {111} and significantly enlarged {011} facets occurred at the surface of the reconstructed Pd crystal. The faceting behavior is in accordance with recently calculated equilibrium shapes of Pd crystals in the presence of small amounts of adsorbed oxygen.info:eu-repo/semantics/publishe

Towards an Advanced Linear International Collider

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 implementation in future accelerators, in particular for high energy physics applications. It complements the overview prepared for the update of the European Strategy for particle physics, and provides a detailed description of the field. The scientific priorities of the community are described for each technique of acceleration able to achieve accelerating gradient in the GeV~range or above. ALEGRO working group leaders have coordinated the preparation of their working group contribution and contributed to editing the documents. The preparation of this document was coordinated by the Advanced LinEar collider study GROup, ALEGRO. The content was defined through discussions at the ALEGRO workshop in Oxford UK, March 2018, and an advanced draft was discussed during a one day meeting prior to the AAC workshop in Breckenridge, CO, USA, August 2018. This document was submitted as an addendum to the ALEGRO submission to the European Strategy for Particle Physics
