Absolute Determination of Charge-Coupled Device Quantum Detection Efficiency Using Si K-Edge X-Ray Absorption Fine Structure (open access)

Absolute Determination of Charge-Coupled Device Quantum Detection Efficiency Using Si K-Edge X-Ray Absorption Fine Structure

We report a method to determine the quantum detection efficiency and the absorbing layers on a front-illuminated charge-coupled device (CCD). The CCD under study, as part of a crystal spectrometer, measures intense continuum x-ray emission from a picosecond laser-produced plasma and spectrally resolves the Si K-edge x-ray absorption fine structure features due to the electrode gate structure of the device. The CCD response across the Si K-edge shows a large discontinuity as well as a number of oscillations that are identified individually and uniquely from Si, SiO{sub 2}, and Si{sub 3}N{sub 4} layers. From the spectral analysis of the structure and K-edge discontinuity, the active layer thickness and the different absorbing layers thickness can be determined precisely. A precise CCD detection model from 0.2-10 keV can be deduced from this highly sensitive technique.

Afghanistan: USAID Oversight of Assistance Funds and Programs

Testimony issued by the Government Accountability Office with an abstract that begins "The U.S. Agency for International Development (USAID) has experienced systemic challenges that have hindered its ability to manage and oversee contracts and assistance instruments in Afghanistan. Key challenges include gaps in planning for the use of contractors and assistance recipients and having visibility into their numbers. For example, GAO reported in April 2010 that, absent strategic planning for its use of contractors, individual offices within USAID often made case-by-case decisions on using contractors to support contract or grant administration and risks, such as possible conflicts of interest, were not always addressed. While having reliable data on contractors and assistance recipients is a starting point for informing agency decisions and ensuring proper management, GAO has also reported on limitations in USAID’s visibility into the number and value of contracts and assistance instruments in Afghanistan, as well as the number of personnel working under them. USAID, along with other agencies, has not implemented GAO’s recommendation to address such limitations. USAID, however, has taken other actions to mitigate risks associated with awarding contracts and assistance instruments in Afghanistan. In June 2011, GAO reported on USAID’s vendor vetting program, then in its …
