设计并制作了用于X射线束位置监测器(XBPM)的新型金刚石探测头。该显示器工作在光导模式，并被塑造成刀片，以减少热负荷。在金刚石刀片的两侧形成一对铝电极。测量了金刚石探测头内部的探测效率分布。信号电流仅在该对电极之间产生。还测量了沿探测器头的一段的信号电流的偏置电压依赖关系。结果表明，探测器头工作在光导模式下。我们证明了该探测器头用于XBPM是可行的。
We designed and fabricated new diamond detector head for an X‐ray beam position monitor (XBPM). This monitor operates in photoconductive mode, and is shaped into a blade in order to reduce heat load. A pair of aluminum electrodes is formed on both sides of the diamond blade. The profile of the detection efficiency inside the diamond detector head was measured. The signal current is generated only between the pair of electrodes. The bias voltage dependence of signal current along a section of the detector head is also measured. The results show that the detector head operates in photoconductive mode. We demonstrated that this detector head is feasible for the XBPM.
