摘要:

描述了一种允许校准和评估光电倍增管阵列的响应线性的方法。该方法不需要光电倍增管单光电子响应模型的知识,直接使用科学数据,从而消除了对专用数据集的需要。通过这种方式,所有光电倍增管的工作条件(例如温度、外部场等)都在校准和科学采集之间精确匹配。这在诸如ZEPLIN-III的低背景实验中特别重要,其中涉及使用外部光源进行校准的方法受到严重限制。

英文摘要:

A method is described that allows calibration and assessment of the linearity of response of an array of photomultiplier tubes. The method does not require knowledge of the photomultiplier single photoelectron response model and uses science data directly, thus eliminating the need for dedicated data sets. In this manner all photomultiplier working conditions (e.g. temperature, external fields, etc) are exactly matched between calibration and science acquisitions. This is of particular importance in low background experiments such as ZEPLIN-III, where methods involving the use of external light sources for calibration are severely constrained.
