摘要:

MAGIC合作正在建造第二台望远镜MAGIC II,改进目前MAGIC望远镜的设计。MAGIC II正在距离MAGIC I 85米处建造,并且还将具有约240米$^2$面积的巨大反射表面。其中一个改进是MAGIC II的镜子设计,更轻,更大,边长为1米,重量约为15公斤。为了开发和生产新的镜子,选择了两种不同的技术,既可靠又价格实惠:铝表面的金刚石铣削和薄玻璃板的冷塌陷。由于第二个测试仍在进行中,我们提出了金刚石铣削技术的描述,其应用和性能的生产镜子。

英文摘要:

The MAGIC Collaboration is building a second telescope, MAGIC II, improving the design of the current MAGIC Telescope. MAGIC II is being built at 85 m of distance from MAGIC I, and will also feature a huge reflecting surface of ~240 m$^2$ of area. One of the improvement is the design for the mirror of MAGIC II, that are lighter and larger, being square of 1 m of side and weighting around 15 kg. For the development and production of the new mirrors, two different techniques, both reliable and affordable in price, were selected: the diamond milling of aluminium surfaces and the cold slumping of thin glass panes. As tests for the second one are still ongoing, we present a description of the diamond milling technique, and its application and performance to the produced mirrors.
