MAESTRO: The MMT Advanced Echelle Spectrograph

摘要 BECHTOLD，J. AST-9622721 这些资金将用于建造多镜望远镜（MMT）高级中阶梯摄谱仪，也就是MAESTRO。MMT是一个6.5米口径的望远镜。 建成后，它将成为世界上第三大望远镜。 MAESTRO采用了许多创新，从而实现了高吞吐量和大波长。 它将在一次曝光中以100，000的分辨率覆盖光谱的可见光和附近的红外和紫外区域（3056埃至1，100埃）。 焦平面将由六个2048 X 4096元CCD阵列组成。 光栅将由两个52 l/mm的复制单元组成，每个复制单元长40 cm。 光束将被两个大的熔融石英棱镜交叉分散。

Abstract BECHTOLD, J. AST-9622721 These funds will be used to build the Multiple Mirror Telescope (MMT) Advanced Echelle Spectrograph, know an MAESTRO.The MMT is a 6.5 meter aperture telescope. On its completion it will be the third largest telescope in the world. MAESTRO incorporates a number of in novations which result in high throughput and large wavelength. It will cover the visible and nearby infrared and ultraviolet regions of the spectrum (3056 Angstroms to 1,100 Angstroms) in a single exposure with a resolution of 100,000. The focal plane will be made up of an array of six 2048 X 4096 element CCD's. The grating will consist of two 52 l/mm replica units each of which is 40 cm long. The beam will be cross-dispersed with two large fused-silica prisms.
