description Measurements of single cavity sections and of two joined sections are reported. The problem of storing heat treated sections until final assembly has been investigated. Flooding a cavity at room temperature with nitrogen deteriorates its performance, after the cavity was once excited to a peak electric field of 30 MV/m, corresponding to a peak magnetic field of 850 G and a deflecting field of 5.5 Mv/m. This effect is assumed to be due to a sensibilization of the surface oxides by field emission electrons. The effect is not observed after an electric field of up to 15 MV/m and it also does not appear when the cavity is flooded with argon. (14 refs).
