$^{7}$Be Solar Neutrino Measurement with KamLAND

KamLAND is a multipurpose, 1-kton liquid scintillation detector located in the Kamioka underground laboratory, in Japan. Two distinct liquid scintillator purification campaigns were performed in 2007 and 2008-2009, where the background event rates from decays of $^{85}$Kr, $^{210}$Bi, and $^{210}$Po were reduced by factors of 6$\times$10$^{-6}$, 8$\times$10$^{-4}$, and 5$\times$10$^{-2}$, respectively. This dramatic suppression of low-energy backgrounds increased KamLAND's sensitivity to new physics below 1 MeV. We report a measurement of the 862 keV $^{7}$Be solar neutrino flux with KamLAND, thereby providing the first independent cross-check of this important quantity. The details of the solar neutrino analysis will be presented, along with a comparison to Standard Solar Model flux predictions.
