Two phases (2223 and 2212) are identified in Bi1.8Pb0.3Sr2Ca2(Cu1-xNix)3.3Oy superconductor system, sintered at 847 °C for 322 h, in partial nitrogen atmosphere. The volume fraction of 2223-phase is strongly dependent on Ni doping: 78.37% for x = 0.

Time variation of optical emission lines for Hg, and other elements detected in a mercury HID lamp before and during X-ray irradiation were analyzed. Various irradiation conditions are causing differences in time dependencies of all Hg spectral line
