Webb1 jan. 2004 · In particular, JWST focal planes must be able to withstand the ionizing-particle radiation environment expected for its Lagrange-point (L2) orbit and ten-year mission lifetime goal. To help ... WebbThe Focal Plane Electronics operated at 290 K. It makes these observations in light from 0.6 (600 nm) to 5 microns (5000 nm) wavelength. It can observe in two fields of view, and either side can do imaging, or …
Radiation environment performance of JWST prototype FPAs
WebbThe JWST Near Infrared Camera (NIRCam) observes from 0.6 to 5.0 μm and offers imaging, coronagraphy, wide field slitless spectroscopy, and time-series monitoring … Webb23 juli 2008 · We present the development of a Focal Plane Module (FPM) for the Mid-Infrared Instrument on JWST. MIRI will include three FPMs, two for the spectrometer channels and one for the imager channel. The FPMs are designed to support the detectors at an operating temperature of 6.7 K with high temperature stability and precision … cirina jacobo

Webbrigorous JWST down- select and RVS was selected to provide the FPA for the mid-IR instrument (MIRI). RVS subsequently won the competition to provide the sixteen 4 Mpxl HgCdTe FPAs for the mosaic focal plane of ESO’s VISTA telescope. A number of other vendors, notably DRS Infrared Technologies in Dallas TX and CEA LETI in Grenoble Webb5 nov. 2024 · The MIRI field is selected from the JWST’s focal plane by a single pick off mirror, with the regions of the field directed to each optical function as shown in Fig. 3, adapted from Wright et al. . The spectral resolution and wavelength coverage of both the MRS and LRS are given in Fig. 1. WebbJWST successfully demonstrates a segmented aperture space telescope and establishes a path to building even larger space telescopes. ciril ribičič
