<p>An electron accelerator comprises a radiation protection chamber (10) provided with a partition (12) which divides, together with a vacuum chamber (1), the radiation protection chamber (10) into two sections (14, 15). One of the sections houses the outlet window (2) of the vacuum chamber (1) whereas the other section houses a device (8) for scanning the electron beam, vacuum pumps (3) and a device (5) for measuring and controlling vacuum. </p> |
