我们描述了一个为研究LSST望远镜的CCDS的最佳运行而建立的系统的调试。该测试系统设计为低振动、高稳定运行，能够照亮平场、投影点、投影图和Fe-55配置的探测器。我们比较和描述了为表现出更亮-更胖效果的CCDs选择增益校准方法时的一些考虑因素。提出了一种改变背衬底偏置和栅时钟电平的增益和富尔韦尔原型器件的优化研究。
We describe the commissioning of a system which has been built to investigate optimal operation of CCDs for the LSST telescope. The test system is designed for lowvibration, high stability operation and is capable of illuminating a detector in flat-field, projected spot, projected pattern and Fe-55 configurations. We compare and describe some considerations when choosing a gain calibration method for CCDs which exhibit the brighter-fatter effect. An optimisation study on a prototype device of gain and fullwell with varying back substrate bias and gate clock levels is presented.
