O169700100030 The mosaic arrangements were irradiated in pairs and O169700100031 one of them was used as a relative monitor of the O169700100032 proton flux. The proton flux was monitored by O169700100033 detection of protons scattered by a 0.1-mm thick O169700100034 stainless steel exit window of the beam line at an O169700100035 angle of about 45-degree by means of a scintillation O169700100036 telescope. O169700100037 SAMPLE Fissile targets were made from separated isotopes of O169700100038 tungsten in the WO(3) chemical form by means of O169700100039 vacuum evaporated onto aluminum backings.
