LBNL built the DOM main boards, and many of our service tasks are related to that; we are responsible for DOMsimulator and DOMcalibrator (Chang Hyon Ha), and work on flasher calibrations, where the original goal was to measure the electronics performance. This includes work on the new (for IC59) SLC isolated hits, an improved baseline determination (needed for accurate charge determination) and a possible improved model for fADC pulse shapes. Our other service activities include member of the Publication Committee (S. Klein), co-chairing the atmospheric/diffuse PWG (S. Klein), work on verification and monitoring, studies of hole ice (L. Gerhardt), Simulation Programs: cmc (L. Gerhardt) and work on reconstruction algorithms (L. Gerhardt, S. Miarecki), and work on the track engine trigger (D. Nygren). L. Gerhardt, in particular, is developing reconstruction algorithms for two parallel tracks, as are found in air showers with high transverse momentum muons, and pairs of upgoing particles that are predicted in some models of supersymmetry. Sandy Miarecki has developed a new method for measuring muon energy which has significantly better resolution than the previous approaches, and is now implementing it in IceTray and fine-tuning it. LBNL is hosting and preparing the Spring 2012 Collaboration Meeting (mostly S. Klein, S. Miarecki, B. Stokstad).

Our analysis efforts are focused in several areas. The first a search for extraterrestrial neutrinos, especially cascades. The second is a search for atypical cosmic-ray showers; events with high transverse momentum muons in showers and photon-initiated showers with a very low muon content. D. VanDerDrift is also interested in upgoing muon pairs, a signature for new physics (the techniques for this are similar to those used for high transverse momentum muons. Finally, Miarecki is working on a measurement of the neutrino-nucleon cross-section by measuring atmospheric neutrino absorption in the Earth; statistics permitting, this will be her PhD dissertation.

We use the National Energy Research Supercomputer Center (NERSC) ‘PDSF (Parallel Distributed Systems Facility) to produce Monte Carlo event samples; this has mostly been cascade signal events. L. Gerhardt maintains the PDSF software installation and coordinates this production. The hardware is maintained by NERSC.
