UCLA Wednesday Seminars

The Milagro Gamma Ray Detector

Prof. Greg Sullivan, University of Maryland

Milagro will be a large water-Cerenkov detector built specifically to study gamma-rays in the energy range from several hundred GeV to ~100 TeV. It is currently being built, in the Jemez mountains near Loa Alamos NM, using a man made pond 60m x 80m x 8m. The detector is currently operating during its second stage of construction as the Milagrito detector. Milagrito is a 1500 m^2 single layer detector instrumented with 228 PMTs and has been taking data since early 1997. This talk will present the preliminary results from Milagrito, including results on detector operation and physics studies.
