摘要:

介绍了一种用于极微弱通量成像的EMCCD相机。CCCP是一款用于光子计数的CCD控制器,它已与e2v technologies的CCD 97 EMCCD集成到蒙特利尔大学天体物理学实验室(LAE)的科学相机中。这款新相机实现了亚电子读出噪声和非常低的时钟感应电荷(CIC)水平,这是极微弱通量成像所必需的。它已在实验室中进行了表征,并在Megantic山天文台的1.6米望远镜上使用。相机的性能进行了讨论和实验数据与第一个科学数据。

英文摘要:

An EMCCD camera, designed from the ground up for extreme faint flux imaging, is presented. CCCP, the CCD Controller for Counting Photons, has been integrated with a CCD97 EMCCD from e2v technologies into a scientific camera at the Laboratoire d'Astrophysique Experimentale (LAE), Universite de Montreal. This new camera achieves sub-electron read-out noise and very low Clock Induced Charge (CIC) levels, which are mandatory for extreme faint flux imaging. It has been characterized in laboratory and used on the Observatoire du Mont Megantic 1.6-m telescope. The performance of the camera is discussed and experimental data with the first scientific data are presented.
