C135600100010 The projected beam profile on target, tilted at C135600100011 75 degree relative to the sample normal, is 1 mm x C135600100012 1.4 mm. C135600100013 METHOD (EDE) C135600100014 Energy loss in the target calculated with the C135600100015 SRIM-2000 code. C135600100016 DETECTOR (TELES) A particle telescope is used to separate and C135600100017 detect hydrogen isotopes. The particle telescope is C135600100018 composed of a 109 microm thick Mylar range foil C135600100019 followed by a curved aperture. C135600100020 (SIBAR) A thin silicon surface barrier detector, C135600100021 Ortec TD-040-300-75-S, of thickness 65.2 microm and C135600100022 active area 300mm2 is located behind the curved C135600100023 aperture. C135600100024 (SIBAR) A thick silicon surface barrier detector, C135600100025 Ortec BU-018-300-300, follows the thin DE detector. C135600100026 SAMPLE The target films used in this experiment were produced C135600100027 by e-beam deposition of 500 nm of erbium onto C135600100028 molybdenum substrates. Hydriding of the erbium was C135600100029 accomplished by exposure of the erbium layer to an C135600100030 overpressure of the appropriate gas at a prescribed C135600100031 temperature and pressure yielding target film C135600100032 stoichiometry of about 2:1 (i.e. ErH2, ErD2 and ErT2).C135600100033 MONITOR Beam energy calibration was carried out using the C135600100034 19F(p,g) resonance at the proton energy of 0.827 MeV C135600100035 as well as the two resonance reactions H(19F,g) and C135600100036 H(19F,g) at the fluorine energy of 16.440 MeV.
