We are conducting a measurement program on back-up filters of the
XMM-Newton EPIC camera aimed at monitoring possible aging effects
during the mission lifetime. One thin and one medium EPIC back-up
filters have been stored since 1997 in an environment similar to that
one of the flight filters (dry nitrogen box before launch, high vacuum
after launch). The transmission of the two filters has been measured
periodically in the 1900-10000 angstrom wavelength range where effects of aging would be clearly evident. The preliminary results, after 5 years of monitoring, show that a slight aging effect has occurred on both filters which, however, has no significant impact onto the EPIC calibration for the correct analysis of the X-ray astrophysical observations.
