The Thermionics chamber consists of two joined vacuum chambers, the main chamber and the load lock. The main chamber and the load lock are separated by a large gate valve which serves to isolate the two sections. | The Thermionics chamber consists of two joined vacuum chambers, the main chamber and the load lock.
