High-Gain Transimpedance Amplifier (TIA) for Night Airglow Photometer
This paper describes a simple, inexpensive transimpedance amplifier (TIA) suitable to convert the fast current pulses delivered by photomultiplier tube of night airglow photometer into the corresponding voltage. Design criteria for the transimpedance amplifier are carefully selected to include low input bias current, offset voltage and noise. The operation of the transimpedance amplifier and th...
متن کاملJupiter's nightside airglow and aurora.
Observations of Jupiter's nightside airglow (nightglow) and aurora obtained during the flyby of the New Horizons spacecraft show an unexpected lack of ultraviolet nightglow emissions, in contrast to the case during the Voyager flybys in 1979. The flux and average energy of precipitating electrons generally decrease with increasing local time across the nightside, consistent with a possible sour...
متن کاملEURD Observations of EUV Nightime Airglow Lines
The extreme ultraviolet (EUV) airglow has yet to be studied extensively due to observational difficulties in this range of the spectrum. EURD is an instrument designed to study diffuse EUV radiation flown on the Spanish MINISAT-01 satellite. In this paper we present observations of the terrestrial night airglow as observed from EURD in the range of 400 to 1060 Å. The high sensitivity and high r...
متن کاملDeep Galaxy Surveys in the 9150 Å Airglow Window
We describe the current status of two complementary programs to search for objects with strong emission lines in a ∼ 300 Å gap, centered at 9150 Å, in the strong airglow emission. Both programs are being carried out with LRIS on the Keck II telescope. The first of these uses broad-band and narrow-band filter photometry to select candidates, followed by multi-slit spectroscopy through the same n...
متن کاملNight sweats
Although night sweating is a common outpatient complaint medical, literature on this subject is scarce. Tuberculosis, brucellosis and lymphoma are diseases in which night sweating is a dominant symptom, but these are infrequently found to be the cause of night sweats in modern practice. While these diseases remain important diagnostic considerations in patients with night sweats, other diagnosi...
