INNOVATION
Developed an imaging intensifier plate with low ion feedback, low dark counts, high gain in a single MCP, and uniformity of response and gain across the plate

ACCOMPLISHMENTS
- Imaging Intensifier
Plate used in a sealed detector system called a Multi-Anode Microchannelplate
Array (MAMA)
- Two types now operating
successfully in the Space Telescope Imaging Spectrograph (STIS)
on the Hubble Space Telescope, with high global and local dynamic
range, high signal-to-noise, long lifetime, and geometric stability
- Unique astronomical
data using the UV imaging, long slit and echelle spectroscopy capabilities
of this instrument are emerging, enabled by the MAMA detectors with
their curved microchannel plates
|
COMMERCIALIZATION
- MAMA detectors will be useful
for high quality industrial inspection where faint UV light is produced
in the presence of strong visible light, such as electric motor
manufacture, and electric power distribution
- Other uses are in time of flight
mass spectrometry (TOFMS), night vision imaging devices, and EUV
and soft x-ray imaging
|
GOVERNMENT/SCIENCE
APPLICATIONS
- In addition to the use of these
microchannelplates in the MAMA detectors in the STIS instrument,
they are being used in further upcoming HST instruments, the
Advanced Camera for Surveys, and the Cosmic Origins Spectrograph
