Issue Date: | 2003 | Publisher: | SPRINGER | Source: | EXPERIMENTAL ASTRONOMY, 16(3). p. 141-148 | Abstract: | Fabrication, packaging and experimental results on the calibration of metal-semiconductor-metal (MSM) photodetectors made on diamond are reported. LYRA (Lyrnan-alpha RAdiometer onboard PROBA-2) will use diamond detectors for the first time in space for a solar physics instrument. A set of measurement campaigns was designed to obtain the XUV-to-VIS responsivity of the devices and other characterizations. The measurements of responsivity in EUV and VUV spectral ranges (40-240 nm) have been carried out by the Physkalisch-Technische Bundesanstalt (PTB) in Germany at the electron storage ring BESSY II. The longer wavelength range from 210 to 1127 nm was measured with monochromatic light by using a Xe-lamp at IMO-IMOMEC. The diamond detectors exhibit a photoresponse which lie in the 35-65 mA/W range at 200 nm (corresponding to an external quantum efficiency of 20-40%) and indicate a visible rejection ratio (200-500 nm) higher than four orders of magnitude. | Notes: | Observ Royal Belgique, B-1180 Brussels, Belgium.
