“…Other results came from the Kurtchatov [22] and Rovno [23] experiments which quoted limits of κ e < 2.4 and < 1.9 at 90% CL, respectively. A recent experiment MUNU [24] at the Bugey reactor adopted a time projection chamber with CF 4 gas surrounded by active liquid scintillator as anti-Compton vetos. A limit of κ e < 0.9 at 90% CL was set with 66.6 days of data at a threshold of 700 keV.…”

A search of neutrino magnetic moments was carried out at the Kuo-Sheng Nuclear Power Station at a distance of 28 m from the 2.9 GW reactor core. With a high purity germanium detector of mass 1.06 kg surrounded by scintillating NaI(Tl) and CsI(Tl) crystals as anti-Compton detectors, a detection threshold of 5 keV and a background level of 1 kg −1 keV −1 day −1 near threshold were achieved. Details of the reactor neutrino source, experimental hardware, background understanding and analysis methods are presented. Based on 570.7 and 127.8 days of Reactor ON and OFF data, respectively, at an average Reactor ON electron anti-neutrino flux of 6.4 × 10 12 cm −2 s −1 , the limit on the neutrino magnetic moments of µν e < 7.4 × 10 −11 µB at 90% confidence level was derived. Indirect bounds on theνe radiative decay lifetimes were inferred.

The status of neutrino oscillation searches employing nuclear reactors as sources is reviewed. This technique, a direct continuation of the experiments that proved the existence of neutrinos, is today an essential tool in investigating the indications of oscillations found in studying neutrinos produced in the sun and in the earth's atmosphere. The low energy of the reactor e makes them ideal for exploring oscillations with small mass differences and relatively large mixing angles. In the last several years the determination of the reactor antineutrino flux and spectrum has reached a high degree of accuracy. Hence measurements of these quantities at a given distance L can be readily compared with the expectation at Lϭ0, thus testing the disappearance of e . Two recent experiments, CHOOZ and PALO VERDE, with baselines of about 1 km and sensitive to the neutrino mass differences associated with the atmospheric neutrino anomaly have collected data and published results recently. An ambitious project with a baseline of more than 100 km, KAMLAND, has now began to take data. This last reactor experiment will have a sensitivity sufficient to explore part of the oscillation phase space relevant to solar neutrino scenarios. It is the only envisioned experiment with a terrestrial source of neutrinos capable of addressing the solar neutrino puzzle. CONTENTS

“…The SM contribution is of the order of 1 kg −1 day −1 at the typical parameters for reactor experiments and detection threshold of 100 keV With the conservative but realistic values of ∆=30% and ξ=3 MeV, the attainable total "1-σ" accuracies for the SM cross-sections are evaluated and depicted in Figure 4a as a function of detection threshold for different values of the measurement error δ det . Also shown are sensitivities for the detection ranges of R 1 =5-100 keV and R 2 =0.5-2 MeV, which correspond to the ranges of the on-going experiments Kuo-Sheng [29] and MUNU [28], respectively. It can be seen that, for the same δ det , measurements with a low threshold are limited by the uncertainties in φ(ν e ).…”

The low energy part of the reactor neutrino spectra has not been measured experimentally. Its uncertainties limit the sensitivities in certain reactor neutrino experiments. This article discusses the origin of these uncertainties and examines their effects on the measurements of neutrino interactions with electrons and nuclei. The discrepancies between previous results and the Standard Model expectations can be explained by the under-estimation of the reactor neutrino spectra at low energies. To optimize the experimental sensitivities, measurements forν e -e cross-sections should focus on events with large (>1.5 MeV) recoil energy while those for neutrino magnetic moment searches should emphasize on events <100 keV. The merits and attainable accuracies for neutrino-electron scattering experiments using artificial neutrino sources are discussed.
