Abstract
The design and calibration of thin-film Zr transmission filters for the Cosmic Hot Interstellar Plasma Spectrometer (CHIPS) spaceborne astronomical telescope is presented. The transmission of a 1000-Å-thick Zr filter is measured for wavelengths from 45 to 1304 Å as well as its variability with respect to expected space-flight environmental extremes of temperature, vibration, and atomic O bombardment. For the CHIPS spectral band of 90–260 Å, the transmission of the Zr filter is deemed useful between 90 and 200 Å and is stable with respect to expected temperature and vibrational changes. The maximum atomic O bombardment decreases the filter transmission between 90 and 130 Å by ∼20% and does not appreciably affect the rest of the CHIPS bandpass. These results make Zr an acceptable filter candidate for CHIPS.
