PURPOSE:To simplify preservation and inspection of parts of an auxiliary power supply by composing an electron gun device en bloc with a high voltage tank on the side of the auxiliary power supply while the high voltage tank is divided in two in a junction spot of the auxiliary power supply and a high voltage electron beam acceleration power supply. CONSTITUTION:In a high voltage tank 1', an upper tank 21 with a built-in high voltage electron beam acceleration power supply 3 and a lower tank 22 with a built-in auxiliary power supply 6 are separably arranged. In the beam acceleration power supply 3, a high voltage boosting transformer 4 is arranged on the upper side, while an acceleration power supply unit 5 is arranged on the lower side and in the auxiliary power supply 6, an auxiliary power supply unit 8 is arranged on the upper side while an insulation transformer 7 is arranged on the lower side. Further, an electron gun device 10 is attached to the lower tank 22 through a junction part 11. Thereby, the inner face of the lower tank 22 is given good visibility thus simplifying preservation and inspection of the parts of the auxiliary power supply. |
