2.5 MeV BNCT RFQ加速器的多物理场分析
Multiphysics Analysis of the 2.5 MeV BNCT RFQ Accelerator
摘要：
硼中子俘获疗法（BNCT）是一种先进的癌症治疗方法，使用众所周知的Li（p，n）Be破坏癌症肿瘤。由于硼与中子之间的高度选择性反应，BNCT对快速扩散的癌症、浸润性癌症（如头颈癌、黑色素瘤、恶性脑肿瘤等）是有效的。162.5 MHz的四叶片加速器将在CW模式下将20 mA H+从35.0 keV加速到2.50 MeV，并提供1.73 * 10^13 n/sec/cm^2的中子产额。热管理将成为最重要的问题。详细的多物理场分析的BNCT的频率偏移进行了研究，并在标称工作条件下的频率偏移进行了预测。利用CST多物理场模型进行了多物理场分析，并通过ANSYS Multiphysics进行了验证。
英文摘要：
Boron Neutron Capture Therapy (BNCT), is an advanced cancer therapy that destroys the cancer tumors using the well-known Li(p,n)Be . Because of the highly selectively reaction between a boron and a neutron, BNCT is effective for rapidly spreading cancer, invasive carcinoma, such as head and neck cancer, melanoma, malignant brain tumors and so on. The PKU RFQ group proposes an RFQ based neutron source for BNCT application. The 162.5 MHz four-vane RFQ will accelerate 20-mA H+ from 35.0 keV to 2.50 MeV in CW mode, and delivers a neutron yield of 1.73*10^13 n/sec/cm^2. The thermal management will become the most important issues. The detailed multiphysics analysis of the BNCT RFQ will be studied, and the RFQ frequency shift during nominal operating condition is also predicted. The multiphysics analysis is performed by using the CST Multiphysics Model and verified with ANSYS Multiphysics.
