摘要
研制了一种可用于测量软X光辐射的X射线二极管(XRD)。该XRD具有结构简单、对偏压及真空度要求较低、响应面积大等特点。分析了XRD的响应时间和饱和电流等特性,给出了能量计算公式,同时采用同步辐射光源对XRD进行了能量标定,标定结果与理论计算结果一致。利用该XRD对毛细管放电类氖氩46.9 nm激光脉宽和能量进行了测量。
We designed a simplified X-ray diode （XRD） to detect soft X-ray emission, which has advantages of simplified structure, bigger response area, and lower requirements for bias voltage and vacuum level. The response time and saturation current were analyzed. Meanwhile, the formula to calculate the energy was established and the XRD was calibrated at synchrotron radiation source. The energy calibration result matches the theoretical calculation one. With this XRD, we measured the pulse width and energy of discharged-pumped Neqike Ar soft X-ray laser of 46.9 nm.
