摘要

金属的增材制造(AM)有可能为未来粒子加速器的建设提供显著的好处。复杂几何形状的低成本制造与由增材制造实现的改进直线设计的效率提高相结合，可能是未来具有成本效益的绿色加速器设施的一种方式。作为概念验证，我们提出了基于AM设计的高效率Zeff=280 MΩ/m, 433.632 MHz IH-DTL腔。在这种情况下，复杂的内部漂移管结构与内部冷却通道是由1.4404不锈钢和纯铜使用增材制造。原型腔，以及不锈钢增材制造部件都镀上了铜。我们介绍了成功的真空测试结果，腔体的低电平射频测量，以及用30kw脉冲功率放大器进行高功率射频测试的准备情况。

Additive Manufacturing of an IH-Type Linac Structure from Stainless Steel and Pure Copper

Additive manufacturing (AM) of metals has the potential to provide significant benefits for the construction of future particle accelerators. The combination of low cost manufacturing of complex geometries in combination with efficiency gains from improved linac design enabled by AM may be one way towards future cost-effective green accelerator facilities. As a proof of concept, we present a high-efficiency Zeff=280 MΩ/m, 433.632 MHz IH-DTL cavity based on an AM design. In this case, the complex internal drift tube structures with internal cooling channels have been produced from 1.4404 stainless steel and from pure copper using AM. The prototype cavity, as well as stainless steel AM parts have been electroplated with copper. We present results from successful vacuum tests, low level RF measurements of the cavity, as well as the status of preparations for high-power RF tests with a 30 kW pulsed power amplifier.
