Abstract

The efficiency of lumogen coated CCDs has been measured as a function of wavelength in the range from 171 angstrom to 1800 angstrom. A decrease in efficiency has been observe as a function of exposure of the lumogen to high levels of radiation at UV and extreme UV wavelengths. The drop in efficiency was found to be most rapid at lower exposure levels, decreasing in rate as the dosage increased.
