紧凑型材料辐照装置（CMIF）项目将为材料辐照研究提供高能、高通量中子源，这将是中国加速器驱动先进核能（ADANE）长期项目不可或缺的。CMIF是一个由10 mA@50 MeV连续波（CW）氘束驱动的Be（d，xn）中子源，具有颗粒流靶。本文对采用倾斜颗粒流作为靶体和热载体的颗粒铍靶进行了数值研究。首先，研究了泄槽流的流量恒定性。其次，研究了辐照条件与束靶参数之间的关系。为了研究这种靶的热处理能力，对靶内的热沉积和传热进行了数值模拟。最后，对背板的散热和辐照损伤进行了研究。
The Compact Materials Irradiation Facility (CMIF) project will provide a high-energy, high-flux neutron source for material irradiation research which will be indispensable for the long-term Accelerator-Driven Advanced Nuclear Energy (ADANE) project in China. CMIF is a Be(d, xn) neutron source driven by a 10 mA @ 50 MeV continuous wave (CW) deuteron beam with a granular flow target. This paper presents numerical studies of a granular beryllium target which adopts inclined granular flow to serve as both the target body and also the heat carrier. First of all, the flow constancy of the chute flow is investigated. Next the relationship between the irradiation conditions and the beam-target parameters is studied. To investigate the heat processing ability of this kind of target, the heat deposition and transfer in the target are simulated numerically. Finally, the heat removal for the backplate and also irradiation damage are investigated.
