The first 22 MeV micron installation for radiation therapy is described with regard to the general design, the beam transport and the gantry. The first measurements of the electron depth dose curves indicate that the distributions obtained are superior to those of most betatrons and linear accelerators. For the same electron beam energy the depth of dose maximum and the 90 or 80 per cent dose level is considerably increased. The 20.9 MV photon beam has similar depth dose characteristics as a 20 MV betatron.
介绍了用于放射治疗的首台22兆电子伏特微米装置的总体设计、束流传输和机架。电子深度剂量曲线的首次测量表明，所获得的剂量分布优于大多数电子感应加速器和直线加速器。对于相同的电子束能量，剂量最大值的深度以及90%或80%剂量水平都有显著增加。20.9兆伏光子束具有与20兆伏电子感应加速器相似的深度剂量特性。
