人们正在努力减小加速器尺寸并提高能源效率。该加速器具有同轴水脉冲形成线（PEL）和螺旋中心导体。在外部尺寸相同的情况下，这种 PEL 存储的能量几乎是 Blumlein 类型的两倍。在没有螺旋内导体的情况下，这种储能优化的PEL具有大约5-6Ω的固定阻抗，这不一定与负载匹配并导致能量损失。通过适当的螺旋线慢波系数，现在可以匹配负载。因此PEL可以同时实现最大能量存储和最大能量传输到负载。成品 PEL 的外径为 35 厘米，长度为 120 厘米。加速器总质量小于1吨。在实验过程中，PEL 通过快速脉冲变压器充电，并驱动 MILO 作为负载。实验结果表明，脉冲变压器最大输出额定值达到1.1 MV，向MILO输送600 kV电压，电子束峰值功率超过30 GW。介绍了 PEL、输出开关、陶瓷二极管的设计和实验结果。 （4页）
Efforts are made to decrease the accelerator size and to increase the energy efficiency. The accelerator features a coaxial water pulse forming line (PEL), with a helical central conductor. This PEL stores nearly twice the energy as the Blumlein type, given the same outer dimensions. Without the helical inner conductor, such energy storage optimized PEL has fixed impedance about 5-6 Ω, which is not necessarily matched to the load and causes energy loss. With appropriate slow wave factor of the helical line, the load can now be matched. So the PEL can achieve the maximum energy storage and the maximum energy transfer to the load simultaneously. The finished PEL has outer diameter 35 cm, and length 120 cm. Total mass of the accelerator is less than 1 ton. During experiments, the PEL is charged by a fast pulse transformer, and drives a MILO as load. Experiment results show that maximum output rating of the pulse transformer reaches 1.1 MV, and 600 kV is delivered to MILO, and e-beam peak power exceeds 30 GW. Design of the PEL, output switch, ceramic diode and experimental results are presented. (4 pages)
