We report accelerated aging tests on three Pt/Ne lamps from the same manufacturing run as lamps installed on the Cosmic Origins Spectrograph (COS). Initial radiometrically calibrated spectra were taken for each lamp at the National Institute of Standards and Technology (NIST). One lamp was aged in air at NIST at a current of 10 mA and 50% duty cycle (30 s on, 30 s off) until failure. Calibrated spectra were taken after 206 h, 500 h, 778 h, 783 h and 897 h of operation. Two other lamps were… CONTINUE READING
