Getting LArSoft in shape for DUNE

This month nus2surf reports on two of the efforts covered in the FD Optimization Task Force report, single-phase far detector reconstruction, and detector optimization studies, led by Tingjun Yang and Xin Qian, and dual-phase (DP) simulation and reconstruction, led by Vyacheslav Galymov. LArSoft, a software environment for event simulation, reconstruction and analysis, serves as the framework for all this work…

Unwinding the APA winding mystery

“Almost everyone who visits to see the APAs and wire-winding machine – physicists, engineers, everybody — asks about how the wires are wound,” said Bob Paulos, director of the Physical Sciences Laboratory (PSL), where the first three APAs for ProtoDUNE-SP are being fabricated. “We have to explain it better…”

Ready to assemble the SP team at CERN

The first long-term traveler for the installation of the ProtoDUNE-SP detector has arrived in Geneva. Fermilab’s Roberto Acciarri, the coordinator for the Detector Integration, Testing and Installation working group, will spend about two years at CERN coordinating these efforts… Acciarri will be a rich source of information for the newcomers — and a great guy to hang out with…

Proto-ProtoDUNE-SP at Ash River

Bill Miller, a key member of the ProtoDUNE-SP team, is leading the effort to prototype the mechanical installation of the TPC components to ensure that all the latches and hinges planned for ProtoDUNE-SP fit and hold the components correctly and securely, to determine what paths the cables will take, and to work out details of the installation procedure for the team at CERN to follow…

Physics for sports fans

Fermilab runs a very popular lecture series for the public each year, and it was only a matter of time before Chang Kee Jung would be tapped to offer an evening of sports and science, based on his Physics of Sports course at Stony Brook University. He focused his September 23 lecture on four sports, volleyball, baseball, (American) football, and soccer.

IHEP China to prototype beamline corrector magnets

A team from IHEP will begin constructing a prototype of a small dipole magnet for the LBNF beamline later this month. The beamline needs 23 of these magnets, used to provide fine tuning of the magnetic field at every focusing location. The prototype should be ready for testing in the February 2017 timeframe.

Extraordinary beamline alignment

Given that the final design for the Far Site Conventional Facilities will be starting soon, nailing down the coordinates for beam alignment is a high priority. Virgil Bocean, senior geodesist with Fermilab, and a team of surveying specialists made a comprehensive set of measurements at SURF in July.
