Detectors

The 5 to 28 micron imager and spectrometer that is slated to fly aboard the JWST in 2018, MIRI (Mid-Infrared Instrument), is equipped with three  flight detector arrays, each 1024 × 1024 pixels, Si:As impurity band conductors, developed by Raytheon Vision Systems.
JPL, in conjunction with the MIRI science team, has selected the three flight arrays along with their spares.
For a thorough review of the detector characteristics and performance, see Rieke et al., Publications of the Astronomical Society of Pacific, Volume 127, Issue 953, pp. 665-674 (2015) and Ressler et al., Publications of the Astronomical Society of Pacific, Volume 127, Issue 953, pp. 675-685 (2015).
The list below includes reports from tests made at the Goddard Space Flight Center during which MIRI was inside ISIM (CV1, CV2, CV3) and tests on specific detectors related issues carried out at the Jet Propulsion Laboratory (JPL) at Pasadena (with the spare detector arrays).
