The Importance of Electromagnetic Shielding in the SOFIA Telescope
01 January 1989
The NASA Stratospheric Observatory for Infrared Astronomy (SOFIA) airborne telescope will be used for noise-limited measurements made with sensitive electronic detectors. These detectors are usually sensitive to spurious electromagnetic radiation and field fluctuations at radio frequencies and at low frequencies near 20 Hz. The instrument builder must make sure that the detector is shielded from the electronically and electromagnetically noisy environment of the airplane.
