JIANG Dikui WU Guanyuan ZHAO Feiyun SUN Baogen DONG Sai. Radiation corrosion of braze weld for BCM in HLS[J]. Nuclear techniques, 2000, (10): 713-717.DOI:
Corrosion and leak happened at brazing of a beam current monitor(BCM ) under the radiation environment of linac and transport line. Corrosion products were analyzed with a rotating anode X- ray diffractometer
and Fe2F5. 7H2O
CuF2. 2H2O and CuF2 were indentified. They are believed to be the compounds of gas and metal ions at brazing with F-from Teflon that is decomposed by radiation.
