The neutron therapy facility at the Radiotherapy Department of the University Hospital Hamburg-Eppendorf is described. This unit has been developed for clinical purposes according to the initiative and conception of the radiotherapist by AEG/Fed. Rep. of Germany and RDI/USA since 1969. The installation was completed at the beginning of 1974. Special treatment head and bed systems allow isocentric treatment and arc or multiple port therapy. For routine work operation conditions of 8 to 12 mA total beam current and 500 kV accelerating voltage are used. The neutron output at 12 mA is about 3.5 x 10(12) n/s giving a phantom dose rate of more than 20 rad/min for a field size of 17.8 x 17.8 cm2 at 80 cm source-skin distance. Technical installations for improvement of dose rate and half-life of the target are planned. Results of physical measurements about neutron energy distributions, contributions from neutrons and gamma-rays to the total absorbed dose, build-up effect, axial and lateral dose distributions as well as isodose profiles for different field sizes in a homogeneous phantom are presented. Bewteen February 1976 and November 1977 up to 180 patients have been treated.
介绍了汉堡-埃彭多夫大学医院放射治疗科的中子治疗设备。自1969年起，该设备由德国联邦共和国的AEG和美国的RDI根据放射治疗师的倡议和构想，为临床目的而开发。该装置于1974年初完成。特殊的治疗头和床系统允许等中心治疗以及弧形或多野治疗。在常规工作中，使用的总束流为8至12 mA，加速电压为500 kV。12 mA时的中子输出约为3.5×10(12) n/s，在源皮距80 cm处，对于17.8×17.8 cm2的射野面积，体模剂量率超过20 rad/min。计划对提高靶剂量率和半衰期的技术装置进行改进。给出了在均匀体模中关于中子能量分布、中子和γ射线对总吸收剂量的贡献、建成效应、轴向和侧向剂量分布以及不同射野面积的等剂量曲线的物理测量结果。在1976年2月至1977年11月期间，已治疗了多达180名患者。
