This book was released on 2020-09-17 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes advances in the understanding of HgCdTe detectors. While long wave (15 μm) infrared detectors HgCdTe detectors have been developed for military use under high background irradiance, these arrays had not previously been developed for astronomical use where the background irradiance is a billion times smaller. The main pitfall in developing such arrays for astronomy is the pixel dark current which plagues long wave HgCdTe. The author details work on the success of shorter wavelength development at Teledyne Imaging Sensors, carefully modeling the dark current–reverse bias voltage curves of their 10 μm devices at a temperature of 30K, as well as the dark current–temperature curves at several reverse biases, including 250 mV. By projecting first to 13 and then 15 μm HgCdTe growth, values of fundamental properties of the material that would minimize tunneling dark currents were determined through careful modeling of the dark current-reverse bias voltage curves, as well as the dark current-temperature curves. This analysis was borne out in the 13 μm parts produced by Teledyne, and then further honed to produce the necessary parameters for the 15 μm growth. The resulting 13 μm arrays are being considered by a number of ground-based astronomy research groups.

This book was released on 2019 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis discusses the ongoing development of large format 2k x 2k pixel 10 [mu]m cutoff wavelength HgCdTe detector arrays for low background space applications. This collaboration among Teledyne Imaging Sensors (TIS), University of Rochester, and NASA JPL seeks to determine the performance of the latest arrays that were produced by TIS for the NEOCam space mission, and characterize the image quality. Analysis of the dark current mechanisms of one array shows that these detector arrays are limited by thermal diffusion current down to ~ 42 K, have some contribution of thermal G-R current down to 41 K, then limited by a 0.2 e−/s light leak in our dewar. The trap-to-band tunneling current that has been the limiting mechanism for a previous generation of detectors is not significant at the applied reverse bias required by NEOCam. In order to demonstrate the ability of these detectors to operate in a space-like environment, proton testing was conducted at the University of California Davis Crocker Nuclear Laboratory. During proton irradiation, the 1k x 1k detector array whose substrate thickness is now the baseline had no measurable substrate luminescence, and the pixels that were hit by a proton recovered after reset. The total operability decreased by a few percent after a cumulative lifetime dose of irradiation, but was still above the NEOCam requirement of >90%. We also assessed the temperature stability and found that the noise measured while the temperature is fluctuating ł50 mK was the same as measured at a constant temperature. Finally in order to assess the probable image quality, we measured the MTF and the effect of residual images"--Pages viii-ix.

Available in PDF, EPUB and Kindle. Book excerpt: The Department of Defense recently highlighted intelligence, surveillance, and reconnaissance (ISR) capabilities as a top priority for U.S. warfighters. Contributions provided by ISR assets in the operational theaters in Iraq and Afghanistan have been widely documented in press reporting. While the United States continues to increase investments in ISR capabilities, other nations not friendly to the United States will continue to seek countermeasures to U.S. capabilities. The Technology Warning Division of the Defense Intelligence Agency's (DIA) Defense Warning Office (DWO) has the critical responsibility, in collaborations with other components of the intelligence community (IC), for providing U.S. policymakers insight into technological developments that may impact future U.S. warfighting capabilities. To this end, the IC requested that the National Research Council (NRC) investigate and report on key visible and infrared detector technologies, with potential military utility, that are likely to be developed in the next 10-15 years. This study is the eighth in a series sponsored by the DWO and executed under the auspices of the NRC TIGER (Technology Insight-Gauge, Evaluate, and Review) Standing Committee.
