本文介绍了一种一次性气球载仪器，它与商业气象无线电探空仪连接，用于测量大气离子产生率。所用的传感器是一个伽马敏感的盖革管，在550 V的偏压下工作，由一个轻量级的变压器供应。电源要求15 Vat10 mA，精密调节用于最大限度地减少盖革管对偏置电压变化的响应。电源电压在15至25 V之间变化时稳定在0.1%，在大气上升过程中，在− 53至25 °C的温度范围内变化小于1%。数字计数器随每个盖革管事件递增，瞬时计数值通过无线电链路遥测，在接收时打上时间戳以获得计数率。导出的离子产生速率曲线与标准参数化到5%一致。
A disposable balloon-carried instrument, interfaced to a commercial meteorological radiosonde for measuring the atmospheric ion production rate, is described. The sensor used is a gamma-sensitive Geiger tube, operated at 550V bias, produced from a lightweight transformerless supply. The supply requires 15Vat10mA, and precision regulation is used to minimize the Geiger tube’s response to bias voltage changes. The supply was stable to 0.1% for supply voltage variations between 15 and 25V, and varied by less than 1% over temperatures from −53to25°C during an atmospheric ascent. A digital counter incremented with each Geiger tube event, and the instantaneous count value was telemetered over a radiolink, time-stamped on reception to obtain the count rate. The derived ion production rate profile agrees with a standard parametrization to 5%.
