Last January, engineers from the DAPNIA laboratory in Saclay France qualified a new electropolishing facility for single cell cavities. Their first electropolished cavity reaches a promising result, above 42 MV/m (megavolts per metre) of accelerating gradient. It allows them to join the global R&D effort on these cavity treatments. The newly qualified electropolishing facility at […]
Demonstrating the ILC Accelerating Gradient
Director’s Corner 6 July 2006 Barry Barish Demonstrating the ILC Accelerating Gradient The central element of the ILC concept is the superconducting RF technology that will be used to accelerate electrons and positrons in the main linac. The choice of accelerating gradient is perhaps the single most important decision we have made, since it determines […]
