I had this sitting around from a previous email on this subject: """ Pocket Photodiode Geiger Counter http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2170812_-1 Specifically check out figure 6: http://www.ifm.umich.mx/~villasen/Com_Vol/RAMIREZ_PINdidodes.pdf >From the following paper: "Photodiodes with small active areas present a resolution of 1.2 - 2.0 keV at room temperature (Aoki and Koyama, 1989; Yamamoto et al., 1989; Ahmad et al., 1990; Gramsch et al., 1992) measured by the peak's full width at half maximum (FWHM). This resolution can be compared to that of cooled Si(L1) detectors coupled to preamplifiers with cooled FET, which is in the range 0.6 - 0.8 keV (Ahmad and Wagner, 1979). Therefore, PIN photodiodes become competitive even for high resolution photon spectroscopy in the keV energy region." "This paper presents some new measurements of discrete and continuous photon spectra, in the energy range 15 - 160 keV, with a photodiode at room temperature" Measurements of discrete and continuous X-ray spectra with a photodiode at room temperature http://diyhpl.us/~nmz787/pdf/Measurements_of_discrete_and_continuous_X-ray_spectra_with_a_photodiode_at_room_temperature.pdf """ -- -Nathan _______________________________________________ dorkbotpdx-blabber mailing list [email protected] http://music.columbia.edu/mailman/listinfo/dorkbotpdx-blabber
