Such an 3027800100017 arrangement does not require correction for the energy 3027800100018 of detected alphas thus resulting in a lower background3027800100019 DETECTOR (TELES) 3027800100020 (SOLST) Charged particle telescope consisting of a 3027800100021 - totally depleted gold surface barrier silicon diode 3027800100022 (80 mm2, 27 mu thick) for the 'dE/dx' detector, 3027800100023 - gold surface barrier silicon diode (300 mm2, 700 mu 3027800100024 thick for the depletion layer) for the 'E' detector.3027800100025 Before each run the energy calibration was checked 3027800100026 using the natural alpha-radioactivity of U-235. The 3027800100027 energy resolution was found to be 50 keV for the 'E' 3027800100028 detector and 160 keV for the telescope. 3027800100029 PART-DET (A) Alpha particles 3027800100030 EN-SEC (E,A) The
