Thinned CCDs for the UH 8192 x 8192 CCD Mosaic Camera

夏威夷大学研制了一种8192x8192像素的CCD拼接相机。马赛克是一个紧密排列的4 × 2 3边可折叠的2048 × 2048 ccd阵列，像素为15微米。该相机主要用于加拿大、法国、夏威夷望远镜的主焦，但也可以与其他望远镜一起使用。可用于该仪器的ccd是质量相当低的原型，有几个严重的限制。该项目将用高质量、高灵敏度（峰值QE为80%）、轻薄的ccd取代现有相机中的原有ccd。改进后的ccd将使仪器的灵敏度在红色中至少提高两倍，在蓝色中提高许多倍。此外，新的ccd将具有卓越的外观质量，并且减少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.
