Hot out of the oven, Saclay team improves cavity baking process

| 5 April 2007 Before accelerating electrons and positrons, cavities need to undergo a number of treatments, such as chemical and electropolishing, the last one being baking. The standard baking procedure heats the cavity at 120°C for two days with an ultra high vacuum (UHV) requirement. These very restrictive conditions are unfortunately not appropriate for the treatment of 16,000 cavities that the ILC requires. Category: Feature | Tagged: , , ,

Above 42 MV/m for a single cell cavity electropolished at Saclay

| 15 March 2007 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.
