We present a high-level architecture for how artificial intelligences might advance and accumulate scientific technological knowledge, inspired by emerging perspectives on human such knowledge. Agents knowledge exercising technoscientific method—an interacting combination of engineering methods. The method maximizes quantity we call "useful learning" via more-creative implausible utility (including the "aha!" moments discovery), as well less-creative plausible utility. Society accumulates...
The Cryogenic Apparatus for Precision Tests of Argon Interactions with Neutrino (CAP- TAIN) program is designed to make measurements scientific importance long-baseline neutrino physics and topics that will be explored by large underground detectors. CAPTAIN detector a liquid argon TPC deployed in portable evacuable cryostat. Five tons are instrumented 2,000 channel photon detection system. Subsequent the commissioning phase, collect data high-energy neutron beamline part Los Alamos Neutron...
We report the first measurement of neutron cross section on argon in energy range 100-800 MeV. The was obtained with a 4.3-h exposure Mini-CAPTAIN detector to WNR/LANSCE beam at LANL. total is measured from attenuation coefficient flux as it traverses liquid volume. A set 2631 candidate interactions divided bins kinetic calculated time-of-flight measurements. These are reconstructed custom-made algorithms specifically designed for data time projection chamber size detector. averaged...
We report an extended measurement of the neutron cross section on argon in energy range 95--720 MeV. The was obtained with a 4.3-hour exposure Mini-CAPTAIN detector to WNR/LANSCE beam at LANL. Compared earlier analysis same data, this includes reassessment systematic uncertainties, particular related unused wires upstream part detector. Using information we doubled fiducial volume experiment and increased statistics by factor 2.4. also shifted from bins time-of-flight bins. This change...
The detector of internally reflected Cherenkov (DIRC) radiation is the ring imaging BABAR at Pep-II SLAC. radiators consist 4.9-m-long rectangular fused silica bars each glued together from four equal pieces. photon a water tank equipped with an array 10752 conventional photomultipliers. current study attempts to identify sources photonic background generated in DIRC bars. A conclusion this work that there are two major sources: one such component consists photons created by delta-ray...
