As the length of insertion devices (ID’s) increase for synchrotron light sources, so does the need to have larger ultra high vacuum (UHV) sealed chambers, which in turn necessitates the use of creative ways of sealing these large chambers in the UHV range (10-11 torrs).The method specified below was used to seal a 4 meter test vacuum chamber successfully in the ultra high vacuum range. This method could be used for sealing ID chambers of lengths larger than 4 meters too due to its simplicity and reduced cost advantage.
