“…The illumination of the diffuser by the HC lamp is performed using a fused-silica condenser and an optical fibre. In addition, the two deuterium lamps (Key & Preston 1980) were used as relative spectral irradiance standards to calibrate the radiometric response Floyd et al 1996). These lamps were originally designed for the SUSIM experiment by Cathodeon Ltd, UK, but instead a new batch of lamps was produced and delivered for SOLAR/SOLSPEC.…”

Context. The SOLar SPECtrum (SOLSPEC) experiment is part of the Solar Monitoring Observatory (SOLAR) payload, and has been externally mounted on the Columbus module of the International Space Station (ISS) since 2008. SOLAR/SOLSPEC combines three absolutely calibrated double monochromators with concave gratings for measuring the solar spectral irradiance (SSI) from 166 nm to 3088 nm. This physical quantity is a key input for studies of climatology, planetary atmospheres, and solar physics. Aims. A general description of the instrument is given, including in-flight operations and performance of the ultraviolet (UV) channel from 175 nm to 340 nm. Methods. We developed a range of processing and correction methods, which are described in detail. For example, methods for correcting thermal behavior effects, instrument linearity, and especially the accuracy of the wavelength and absolute radiometric scales have been validated by modeling the standard uncertainties. Results. The deliverable is a quiet Sun UV reference solar spectrum as measured by SOLAR/SOLSPEC during the minimum of solar activity prior to cycle 24. Comparisons with other instruments measuring SSI are also presented.

“…Two series of measurements were performed. Between the two series the ion source was in use for roughly 400-500 hours, which caused aging of the UV-lamp window and of the cathode window due to solarization [14]. The lamp was replaced before the second series of measurements.…”

An electron-impact ion source based on photoelectron emission was developed for ionization of gases at pressures below 10(-4) mbar in an axial magnetic field in the order of 5 T. The ion source applies only dc fields, which makes it suitable for use in the presence of equipment sensitive to radio-frequency (RF) fields. The ion source was successfully tested under varying conditions regarding pressure, magnetic field, and magnetic-field gradient, and the results were studied with the help of simulations. The processes in the ion source are well understood, and possibilities for further optimization of generated ion currents are clarified.

“…In the last decade the use of vuv radiation has steadily been growing. Today radiometric techniques are well established with calibrated transfer standard sources for wavelength 3115 nm, such as the deuterium lamp (Einfeld et a1 1978, Key andPreston 1980), and the wall-stabilised argon mini-arc (Bridges andOtt 1977, Einfeld er a1 1979). In the wavelength region below 115 nm, reliable and easy to use transfer standard sources are still missing.…”

Abstract. The vuv line emission of a high-current DC hollow cathode was investigated in the wavelength region 10 nm to 100 nm. Spectra of quadruply ionised atoms could be observed.The radiance in the AI IV lines at 13 nm and 16 nm and in the He I1 Lyman-series was determined by a comparison with the spectral concentration of radiant intensity of the synchrotron radiation emitted by the electron storage ring BESSY. We found the radiance of the lines to be reproducible within 5 2 5 % .
