直流X射线模拟电缆X射线响应的可行性

本文对电缆X射线辐照响应的机理和模拟方法进行了研究，分析了电缆直流和脉冲X射线辐照响应的异同。建立了带状电缆X射线辐照响应一维计算模型，该模型包含电缆屏蔽层和介质层间隙、介质层瞬态辐射感应电导率等计算模型，模拟了带状电缆直流和脉冲X射线辐照电流响应。模拟结果表明，在X射线注量相同的条件下，电缆直流和方波脉冲X射线响应具有类似的波形特征及相同的间隙电压。因此，在该计算模型描述的电缆X射线辐照响应机制下，可利用直流X射线开展相应的脉冲X射线辐照响应机制模拟。

Feasibility of Using Continuous X-ray to Simulate Cable Response Under X-ray Environment

The mechanism and simulating method of cable response induced by X-ray were researched, and the relationship of cable response irradiated by continuous and pulsed X-ray was analyzed. A one-dimension model of strip line irradiation response of X-ray was given, which includes the gap between cable shield and dielectric, and induced conductivity in cable dielectric. The calculation result using the model indicates that the cable responses of continuous and rectangular-pulsed X-ray have the similar current waveform and the same gap voltages. Therefore, continuous X-ray can be used to research some cable responses of pulsed X-ray irradiation under the mechanism described in the one-dimension model.
