摘要:

MAGIC包括两个17米直径的IACT,以立体声模式运行。目前,我们正在调试第二台望远镜MAGIC II。第二个望远镜的相机配备了1039个0.1度直径的像素。总是将七个像素分组在六边形配置中以形成集群。这种模块化设计使相机的控制和维护更容易。像素传感器是来自Hamamatsu的高量子效率光电倍增管(PMT)(超双碱型,在峰值波长处QE ~ 32%),我们在30 k的相当低的增益下操作。这使得我们也可以在中等月光下进行扩展观测。与MAGIC I相比,两台MAGIC望远镜的系统将至少增加一倍的灵敏度,并且还将允许我们降低能量阈值。在这里,我们将报告第二台MAGIC望远镜相机的性能。

英文摘要:

MAGIC comprises two 17m diameter IACTs to be operated in stereo mode. Currently we are commissioning the second telescope, MAGIC II. The camera of the second telescope has been equipped with 1039 pixels of 0.1-degree diameter. Always seven pixels are grouped in a hexagonal configuration to form a cluster. This modular design allows easier control and maintenance of the camera. The pixel sensors are high quantum efficiency photomultiplier tubes (PMTs) from Hamamatsu (superbialkali type, QE ~ 32% at the peak wavelength) that we operate at rather low gain of 30 k. This allows us to also perform extended observations under moderate moonlight. The system of two MAGIC telescopes will at least double the sensitivity compared to MAGIC I and also will allow us to lower the energy threshold.Here we will report the performances of the Camera of the second MAGIC telescope.
