High-voltage Silicon Solar Cells with Vertical p-n Junctions: Evolution, Technology and Special Applications

30 years Odyssey story of solar cells with vertical p-n junctions having low internal losses, high output voltage rating, low manufacturing costs, and robust reliability will be covered. Unusual geometry of structures with vertical p-n junctions can find application as nuclear particle detectors.

Recent Status of Neutrino Oscillation Phenomenology -- after KamLAND

First I will give a brief introduction on neutrino oscillation, and summarize the results in favor of neutrino oscillation (atmospheric neutrinos, solar neutrinos and KamLAND (and possibly LSND)). I will also mention about phenomenology of future long baseline experiments and reactor experiments. I will try to present my talk so that non-experts understand the recent situation of the subject.

Linear Collider Seminar

The American Linear Collider Physics Group (ALCPG) has initiated a series of monthly seminars intended for a broad audience. The seminars will be held in virtual rooms using talks posted to the web, phone conferences, and VRVS. This is the inaugural seminar.

Four-fermion Production with the OPAL Detector at LEP

Four-Fermion final states in electron positron collisions are observed with the OPAL detector at LEP in the data taken in the years 1997 to 2000. This process is a background to many searches, especially Higgs searches, and the measurement of its cross-section is essential. The total cross-sections for e+e- --> qqee and e+e- --> qqmm are measured within kinematic limits defined by the acceptance of the detector. Mass spectra are reconstructed and compared to Monte Carlo predictions.
