    • Characterization of Three-Dimensional-Integrated Active Pixel Sensor for X-Ray Detection 

      Bautz, Marshall W.; Busacker, David E.; Prigozhin, Gregory; Suntharalingam, Vyshnavi; Foster, Richard F.; e.a. (IEEE transactions on electron devicesInstitute of Electrical and Electronics Engineers, 2009-11)
      We have developed a back-illuminated active pixel sensor (APS) which includes an SOI readout circuit and a silicon diode detector array implemented in a separate high-resistivity wafer. Both are connected together using a ...
    • Detection of Reflection Features in the Neutron Star Low-Mass X-Ray Binary Serpens X-1 with NICER 

      Ludlam, R. M.; Miller, J. M.; Arzoumanian, Z.; Bult, P. M.; Cackett, E. M.; e.a. (IOP Publishing, 2018-05)
      We present Neutron Star Interior Composition Explorer (NICER) observations of the neutron star (NS) low-mass X-ray binary Serpens X-1 during the early mission phase in 2017. With the high spectral sensitivity and low-energy ...
    • Front- and back-illuminated X-ray CCD performance in lowand high-earth orbit: Performance trends of Suzaku XIS and Chandra ACIS detectors 

      La Marr, Beverly J.; Grant, Catherine E.; Kissel, Steve E.; Prigozhin, Gregory; Bautz, Mark W.; e.a. (Society of Photo-Optical Instrumentation Engineers, 2009-07)
      Since the launch of the Suzaku X-ray astronomy satellite into low- earth orbit in July, 2005, the performance of the CCD detectors in the X-ray Imaging Spectrometer (XIS) detectors have slowly degraded, as expected, due ...
    • Ground calibration of the Silicon Drift Detectors for NICER 

      Gendreau, Keith C.; Arzoumanian, Zaven; Markwardt, Craig B.; Baumgartner, Wayne H.; La Marr, Beverly J; e.a. (SPIE, 2016-07)
      The Neutron star Interior Composition ExploreR (NICER) is set to be deployed on the International Space Station (ISS) in early 2017. It will use an array of 56 Silicon Drift Detectors (SDDs) to detect soft X-rays (0.2 - ...
    • Interpixel crosstalk in a 3D-integrated active pixel sensor for x-ray detection 

      La Marr, Beverly J.; Bautz, Mark W.; Foster, Rick; Kissel, Steve E.; Prigohzin, Gregory; e.a. (SPIE, 2010-07)
      MIT Lincoln Laboratories and MIT Kavli Institute for Astrophysics and Space Research have developed an active pixel sensor for use as a photon counting device for imaging spectroscopy in the soft X-ray band. A silicon-on-insulator ...
    • Measurement results for an x-ray 3D-integrated active pixel sensor 

      Prigozhin, Gregory; Foster, Richard F.; Suntharalingam, Vyshnavi; Kissel, Steve E.; La Marr, Beverly J.; e.a. (SPIE, 2010-07)
      We have developed a hybrid Active Pixel Sensor for detecting low energy X-rays. The sensor consists of a silicon diode detector array built on a high resistivity wafer and an SOI CMOS readout circuit, connected together ...
    • The Neutron star Interior Composition Explorer (NICER): design and development 

      Egan, Mark; Foster, Richard F; La Marr, Beverly J; Malonis, Andrew C.; Prigozhin, Gregory; e.a. (SPIE, 2016-06)
      During 2014 and 2015, NASA's Neutron star Interior Composition Explorer (NICER) mission proceeded successfully through Phase C, Design and Development. An X-ray (0.2-12 keV) astrophysics payload destined for the International ...
    • NICER instrument detector subsystem: description and performance 

      Prigozhin, Gregory; Gendreau, Keith; Doty, John P.; Arzoumanian, Zaven; Baumgartner, Wayne; e.a. (SPIE, 2016-07)
      An instrument called Neutron Star Interior Composition ExploreR (NICER) will be placed on-board the International Space Station in 2017. It is designed to detect soft X-ray emission from compact sources and to provide both ...
    • Testing and characterization of the TESS CCDs 

      Thayer, Carolyn T.; Villasenor, Jesus Noel Samonte; Kissel, Steve E; La Marr, Beverly J; Morgan, Edward H; e.a. (SPIE-Intl Soc Optical Eng, 2016-07)
      The Transiting Exoplanet Survey Satellite (TESS) is an Explorer-class mission dedicated to finding planets around bright, nearby stars so that more detailed follow-up studies can be done. TESS is due to launch in 2017 and ...
    • Using ACIS on the Chandra X-ray Observatory as a particle radiation monitor 

      Grant, Catherine E.; La Marr, Beverly J.; Bautz, Marshall W.; O'Dell, S. L. (SPIE, 2010-07)
      The Advanced CCD Imaging Spectrometer (ACIS) is one of two focal-plane instruments on the Chandra X-ray Observatory. During initial radiation-belt passes, the exposed ACIS suffered significant radiation damage from trapped ...
