The Grid2003 Project has deployed a multivirtual organization, application-driven grid laboratory (Grid3) that sustained for several months the production-level services required by physics experiments of Large Hadron Collider at CERN (ATLAS and CMS), Sloan Digital Sky Survey project, gravitational wave search experiment LIGO, BTeV Fermilab, as well applications in molecular structure analysis genome analysis, computer science research projects such areas job data scheduling. infrastructure...
In early 2010, the Long-Baseline Neutrino Experiment (LBNE) science collaboration initiated a study to investigate physics potential of experiment with broad set different beam, near- and far-detector configurations. Nine initial topics were identified as scientific areas that motivate construction long-baseline neutrino very large far detector. We summarize justification for each topic estimated performance detector reference report also on optimized beam parameters capability proposed Near...
ProtoDUNE-SP is the single-phase DUNE Far Detector prototype that under construction and will be operated at CERN Neutrino Platform (NP) starting in 2018. ProtoDUNE-SP, a crucial part of effort towards first 10-kt fiducial mass far detector module (17 kt total LAr mass), significant experiment its own right. With liquid argon (LAr) 0.77 kt, it represents largest monolithic LArTPC to built date. It's technical design given this report.

This paper describes spectra of quasar candidates acquired during the commissioning phase Low‐Resolution Spectrograph Hobby‐Eberly Telescope. The objects were identified as possible quasars from multicolor image data Sloan Digital Sky Survey. 10 sources had typical r' magnitudes 19–20, except for one extremely red object with ≈ 23. data, obtained exposure times between and 25 minutes, reveal that four are essentially featureless not quasars, five redshifts 2.92 4.15 (including broad...
Fermilab supports a scientific program that includes experiments and scientists located across the globe. In order to better serve this community, has placed its production computer resources in Campus Grid infrastructure called 'FermiGrid'. The FermiGrid allows large at have priority access their own resources, enables sharing of these an opportunistic fashion, movement work (jobs, data) between National Grids such as Open Science (OSG) Worldwide LHC Computing Collaboration (WLCG). support...
Fermilab provides a multi-petabyte scale mass storage system for high energy physics (HEP) experiments and other scientific endeavors. We describe the scalability aspects of hardware software architecture that were designed into to permit us multiple petabytes capacity, manage tens terabytes per day in data transfers, support hundreds users, maintain integrity. discuss detail how we over time meet ever-increasing needs community, relate our experiences with many technical economic issues...

The VAXONLINE software system, started in late 1984, is now use at 12 experiments Fermilab, with least one VAX or MicroVax. Data acquisition features provide for the collection and combination of data from more sources, via a list-driven Event Builder program. Supported sources include CAMAC, FASTBUS, Front-end PDP-11's, Disk, Tape, DECnet other processors running VAXONLINE. This paper describes functionality provided by gives performance figures discusses ongoing program enhancements.
The VAXONLINE data acquisition package has been extended to include a VME-based path. resulting environment, PAN-DA, provides high throughput for logging, filtering, formatting, and selecting events. authors describe the history rationale of system, VME hardware modules, PAN-DA systems coordination, system connectivity.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
We present the properties of two candidate massive ($M_\star\sim10^{11}M_\odot$) and dusty ($A_{\rm v}>2.5$ mag) galaxies at $z=5-7$ in first 0.28 deg$^2$ COSMOS-Web survey. One object is spectroscopically confirmed $z_{\rm spec}=5.051$, while other has a robust phot}=6.7\pm0.3$. Thanks to their extremely red colors ($F277W-F444W\sim1.7$ mag), these satisfy nominal color-selection for widely-studied ``little dot" (LRD) population with exception spatially-resolved morphologies. The morphology...
Fermilab, in collaboration with the DESY laboratory Hamburg, Germany, has created a petabyte scale data storage infrastructure to meet requirements of experiments store and access large sets. The Fermilab consists following major transfer components: Enstore mass system, DCache distributed cache, FTP grid for primarily external transfers. This provides throughput sufficient transferring from experimental acquisition systems. It also allows framework.
This document describes the Fermilab Data Storage System Enstore, its design concepts, structure, and current status. Enstore provides storage of data in robotic tape libraries according to requirements experiments. High fault tolerance availability, as well multilevel priority based request processing allows experiments effectively store access Enstore. Amount stored system currently approaches 2 PBytes. The includes 5 libraries, more than 100 PC nodes, 90 drives. distributed structure...

As astronomical data grows in volume and complexity, the scalability of analysis software becomes increasingly important. At same time, astrophysics relies heavily on open-source contributions, so languages tools that prioritize both performance readability are especially valuable. Julia, with its just-in-time compiler high level syntax, offers a compelling alternative to traditional like Python or C. In this paper, we outline ShOpt.jl, new package for point spread function (PSF)...
