The result of the neutrino magnetic moment measurement at the Kalinin Nuclear Power Plant (KNPP) with GEMMA spectrometer is presented. The antineutrino-electron scattering is investigated. A high-purity germanium detector with a mass of 1.5 kg placed at a distance of 13.9 m from the 3 GWthreactor core is exposed to the antineutrino flux of2.7×10131/cm2/s. The recoil electron spectra taken in 18134 and 4487 hours for the reactor ON and OFF periods are compared. The upper limit for the neutrino magnetic momentμν<  2.9×10−11μBat 90% C.L. is derived from the data processing.

The result of the neutrino magnetic moment (NMM) measurement at the Kalinin Nuclear Power Plant (KNPP) with GEMMA spectrometer is presented. The antineutrinoÄelectron scattering is investigated. A high-purity germanium (HPGe) detector with a mass of 1.5 kg placed at a distance of 13.9 m from the 3 GW th reactor core is exposed to the antineutrino ux of 2.7 • 10 13 cm −2 • s −1. The recoil electron spectra taken in 18134 and 4487 h for the reactor ON and OFF periods are compared. The upper limit for the NMM μν < 2.9 • 10 −11 μB at 90% C.L. is derived from the data processing.

The hard carbon volumetric capacity improves by decreasing the electrode porosity after calendaring (d002 decrease). The initial CCoulombic efficiency is enhanced when the specific surface area of ultra-micropores and the active sites are diminished.
