Thinned CCDs for the UH 8192 x 8192 CCD Mosaic Camera

AST 9530075 摘要 UH 8192 x 8192镶嵌相机的薄型CCD 夏威夷大学研制了一台8192x8192像素的CCD镶嵌相机。 马赛克是一个紧密堆积的4x2阵列的3边对接2048x2048 CCD与15微米像素。 该相机主要设计用于加拿大法国夏威夷望远镜的主焦点，但也可以用于其他望远镜。 可用于该仪器的CCD是具有几个严重限制的相当低质量的原型。 该项目将用高质量、高灵敏度（峰值QE 80%）、薄型CCD取代现有相机中的原始CCD。 改进的CCD将使仪器的灵敏度在红色中至少增加两倍，在蓝色中增加许多倍。 此外，新CCD将具有上级外观质量，并且降低的暗电流和由此产生的低噪声将使低背景成像项目成为可能。

AST 9530075 Abstract Thinned CCDs for the UH 8192 x 8192 mosaic camera The University of Hawaii has built a CCD mosaic camera with 8192x8192 pixels. The mosaic is a close-packed 4x2 array of 3-edge-buttable 2048x2048 CCDs with 15 micrometer pixels. The camera was designed primarily for use at the prime focus of the Canada France Hawaii Telescope, but can be used with other telescopes as well. The CCDs which were available for use in this instrument are prototypes of rather low quality with several serious limitations. This project will replace the original CCDs in the existing camera with high-quality, high sensitivity (peak QE 80%), thinned CCDs. Improved CCDs will increase the sensitivity of the instrument by at least a factor of two in the red and by a factor of many in the blue. Furthermore, the new CCDs will be of superior cosmetic quality, and the reduced dark current and resulting low noise will make low background imaging projects possible.
