A versatile beamstop with an integrated sensor has been developed at the Stanford Synchrotron Radiation Laboratory (SSRL) using non-specialized components. A diameter of 1.5 mm was achieved using a commercial subminiature surface mount PIN diode (Phillips BAP64) molded into a tungsten epoxy composite cup. The cup is supported on a thin fiberglass arm with printed circuit traces to transmit the signal from the diode. The assembly has an active area of approximately 100 micro m in diameter. As the diode is encapsulated in plastic, the response diminishes with decreasing energy but is still useful at 6 keV.
斯坦福同步辐射实验室（SSRL）利用非专用部件开发出了一种带有集成传感器的多功能束流阻挡器。通过将一个商用超小型表面贴装PIN二极管（飞利浦BAP64）模压到钨环氧树脂复合杯中，实现了1.5毫米的直径。该杯体由带有印刷电路走线的薄玻璃纤维臂支撑，用于传输来自二极管的信号。该组件的有效直径约为100微米。由于二极管封装在塑料中，其响应随能量降低而减弱，但在6千电子伏特时仍有用处。
