NIRSpec Detector Subsystem

Characterization of the James Webb Space Telescope’s Near Infrared Spectrograph (NIRSpec) Detector Subsystem, which consists of two Teledyne Imaging Sensors (TIS) H2RG 5 µm λco HgCdTe 2K x 2K infrared arrays, two cryogenic TIS SIDECAR ASICs, and the Goddard developed room temperature Focal Plane Electronics (FPE).

Thermal Infrared Sensor (TIRS) Focal Plane Array

Characterizing quantum well infrared photodetector (QWIP) thermal IR arrays operation from 10.5 to 12.3 µm for the TIRS instrument on the LandSat Data Continuity Mission (LDCM).

USNO

Characterization of TIS H4RG 4K x 4K HyVisI visible imaging arrays and the development of a test cryostat for use in ground-based astronomy for the United States Naval Observatory.

Linear Etalon Imaging Spectral Array (LEISA) instrument of the New Horizons mission to Pluto

Characterized 2.5 µm λco PICNIC HgCdTe 256 x 256 infrared arrays.

Advanced Camera for Surveys Repair for the Hubble Space Telescope

The DCL played an essential role in the development of the SIDECAR ASIC-based replacement electronics the for repair of the ACS instrument on the Hubble Space Telescope.
