An Update on Progress at KamLAND
  The first generation of solar neutrino experiments narrowed the allowed flavor mixing and mass parameter solutions (for nu_e <-> nu_x) to a few isolated regions of sin^2*2*theta - delta M^2 parameter space. Recently, the Small Mixing Angle (SMA) solution, and the ``just so'' solutions have been disfavored by results from Super-Kamiokande and SNO. The Kamioka Liquid scintillator Anti-Neutrino Detector (KamLAND) recently became operational, and is particularly sensitive to the Large Mixing Angle (LMA) region. We believe the background impurity levels in the detector are low enough to conduct a successful experiment. The stability of the central balloon and PMTs has also been confirmed.
