【摘要】 文章介绍了6MeV全密封边耦合驻波加速管的研制概况,该加速管的整管长度为0.33m,电子枪为三极皮尔斯型,阳极电压为-8KV DC,在采用脉冲功率为2.6 MW,脉冲宽度为4.2μs,重覆频率为280 Hz的脉冲磁控管作微波功率源时,可以在离靶1m处获得吸收剂量率约为6.4 Gy/min的X线,靶点约为φ2mm。更多还原

【Abstract】 The paper presents 6 MeV sealed--off side--coupled standing wave accelerating tubes with the gridcontrolled electron guns. The gun anode voltage is 8 kV DC. The total length of the accelerating tubesis only 0.33 m. High output X--rays with dose rate up to 6.4 Gy/min at 1 meter from target can beobtained by the tubes when a 2.6 MW, 4.2μs, 280 Hz pulse magnetron is used as RF power source.The beam spot diameter is less than 2 mm.更多还原
