Accelerator-driven neutron sources have been developed worldwide for boron neutron capture therapy (BNCT) instead of nuclear reactors. Nagoya University is currently developing a compact DC accelerator driven BNCT system using a sealed lithium (Li) target. The target receives a high heat load by a proton beam, and the heat then requires efficient removal. This study developed a high-efficiency heat removal technique that uses V-shaped staggered ribs on the heat removal side of the flow channels. We performed experiments using an electron beam to confirm the technique performance. The results showed double the heat removal performance compared to the smooth surface channel. The value expected to sufficiently remove 6.6 MW/m² of heat load provided by the proton beam at the Nagoya University neutron source for BNCT.

加速器驱动的中子源已在世界范围内开发用于硼中子俘获疗法 (BNCT)，而不是核反应堆。名古屋大学目前正在开发一种使用密封锂 (Li) 靶的紧凑型直流加速器驱动的 BNCT 系统。目标通过质子束接收高热负荷，然后需要有效去除热量。本研究开发了一种高效散热技术，该技术在流道散热侧使用 V 形交错肋。我们使用电子束进行实验以确认技术性能。结果表明，与光滑表面通道相比，散热性能提高了一倍。预计可充分去除 6.6 MW/m ^{2 的值} 名古屋大学中子源的质子束为 BNCT 提供的热负荷。
