摘要
The variation of the radiation field around accelerator is complex.Only by real-time monitoring can one learn them in detail.The traditional measurement methods have been out of date.The mini-DDL is a specific device designed for such radiation field real-time monitoring.It has huge flash memories and is small in size.It can communicate with the control PC via intranet or RS232 port.So it is suitable to be applied not only in area monitoring but also in temporary monitoring.The radiation field measurements results obtained using the Mini-DDL are introduced in this paper.
各种类型加速器周围的辐射场变化是很复杂的,只有对其进行连续的实时监测才能准确地掌握全面资料.以往的数据采集系统用的是模拟信号长距离传输方式,采集器体积较大,存储技术上也显落后,已不能适应当今的需求.为辐射场实时监测研制的微型数据采集器采用了先进的设计理念,具有体积小、通讯能力强、数据存储量大且断电数据不丢失的特点,可运行于局域网环境.它既可利用局域网远距离向控制计算机传递数据,也可用便携式PC通过串口就近读取数据.所以它不但适于固定场所的连续监测,也可灵活地用于临时测量场所.介绍了它的主要性能和在各类型加速器周围所做测量的结果.
