Multi-year search for a diffuse flxu of muon neutrinos with AMANDA-II (open access)

Multi-year search for a diffuse flxu of muon neutrinos with AMANDA-II

A search for TeV-PeV muon neutrinos from unresolved sources was performed on AMANDA-II data collected between 2000 and 2003 with an equivalent livetime of 807 days. This diffuse analysis sought to find an extraterrestrial neutrino flux from sources with non-thermal components. The signal is expected to have a harder spectrum than the atmospheric muon and neutrino backgrounds. Since no excess of events was seen in the data over the expected background, an upper limit of E{sup 2}{Phi}{sub 90%C.L.} < 7.4 x 10{sup -8} GeV cm{sup -2} s{sup -1} sr{sup -1} is placed on the diffuse flux of muon neutrinos with a {Phi} {proportional_to} E{sup -2} spectrum in the energy range 16 TeV to 2.5 PeV. This is currently the most sensitive {Phi} {proportional_to} E{sup -2} diffuse astrophysical neutrino limit. We also set upper limits for astrophysical and prompt neutrino models, all of which have spectra different than {Phi} {proportional_to} E{sup -2}.

Shielding Calculations for NSLS-II Beamlines. (open access)

Shielding Calculations for NSLS-II Beamlines.

Brookhaven National Laboratory is in the process of designing a new Electron Synchrotron for scientific research using synchrotron radiation. This facility, called the 'National Synchrotron Light Source II' (NSLS-II), will provide x-ray radiation of ultra-high brightness and exceptional spatial and energy resolution. It will also provide advanced insertion devices, optics, detectors, and robotics, and a suite of scientific instruments designed to maximize the scientific output of the facility. The project scope includes the design, construction, installation, and commissioning of the following accelerators: a 200 MeV linac, a booster accelerator operating from 200 MeV to 3.0 GeV, the storage ring which stores 500 mA current of electrons at an energy of 3.0 GeV and 56 beamlines for experiments. It is planned to operate the facility primarily in a top-off mode, thereby maintaining the maximum variation in stored beam current to < 1%. Because of the very demanding requirements for beam emittance and synchrotron radiation brilliance, the beam life-time is expected to be quite low, on the order of 2 hours. Each of the 56 beamlines will be unique in terms of the source properties and configuration. The shielding designs for five representative beamlines are discussed in this paper.

Oral History Interview with William P. Gattis, April 13, 2008 transcript

Oral History Interview with William P. Gattis, April 13, 2008

The National Museum of the Pacific War presents an interview with William P Gattis. Gattis joined the Navy in May of 1941. Soon after joining, he was assigned to the USS Henderson (AP-1). Upon arriving at Pearl Harbor, Gattis volunteered to join the submarine forces. He was quickly assigned to the USS Sargo (SS-188). They departed Pearl Harbor in October of 1941, arrived in Manila in November, and were there when the Japanese attacked. He was later transferred off the Sargo to the Great Lakes Naval Training Station to complete Chief Commissary Steward School, and was then assigned to the USS Salmon (SS-182). In April of 1945, he was transferred to the USS Stickleback (SS-415). He was discharged in Mary of 1947.
