Abstract
The present invention provides an electrical feed-through () for making a durable and reliable electrical connection through a wall () of a vacuum chamber (). The electrical feed-through () comprises a tubular member having an open end () and a closed end (). At least one conductor () extends through the closed end () and is fixed thereto by a vacuum sealing joint (). The joint () is arranged so that it is not in line-of-sight from the open end (). In this way impinging elements () and direct heat radiation () is prevented from directly reaching the joint (), thereby extending the time it takes for contamination of the joint () to cause problems.
