New atmosphere for beamline target chase

The LBNF beamline design originally called for an air-filled/air-cooled target chase, the enclosure in which the target and horns are installed. The older NuMI beamline, however, which also used air, brought to light some issues that the LBNF team needed to consider. The LBNF beamline project has selected nitrogen as the atmosphere for the target chase…


June activities in EHN1

CERN staff, contractors, and visiting collaborators are very busy this month in EHN1, where the two ProtoDUNEs are housed. Insulation panels, clean room walls, the cold box for APA testing, cooled racks for DAQ, computing, and storage, impedance monitoring — a lot is going on…


Getting the green light

Transparent acrylic bars are flying the friendly skies as the Photon Detector group purchases, prepares, tests and assembles the ProtoDUNE-SP light-readout system. From vendors on the east coast, to production and test sites in the Midwest, to assembly in the Rockies, they are destined for installation in the Pays de Gex…


ProtoDUNE-DP proceeding toward construction

The ProtoDUNE-DP Technical Design Review that took place 24-25 April at CERN was a “non-trivial exercise” for the review committee, according to Dario Autiero, one of the project coordinators. After examining the entire detector design, the committee declared the technical design to be “well advanced” and supported “proceeding toward construction…”


The green giant

A production facility for the single-wavelength-shifting light guide is turning on. Matt Toups and his team, with their Operational Readiness Clearance in hand, have just set up their first production light guide bar for dip-coating in a solution of wavelength-shifting TBP…


ND workshop: From here to there

DUNE held a Near Detector Workshop at Fermilab on March 27-29 to launch the Near Detector Concept Study. During his introduction, Mark Thomson welcomed everyone, both DUNE collaborators and interested scientists who are not yet members of DUNE, emphasizing the broad international partnership that is required for this effort…


All work and no play? No way…

“People function better when they are happy,” said Chang Kee Jung, a professor at Stony Brook University who has enjoyed teaching and mentoring young people for many years. “And people are happier when they have social connections…”


International agreement for beamline corrector magnets

Over the last several months, the U.S. DOE and IHEP prepared a formal agreement in which IHEP would construct 24 corrector magnets for LBNF over a thee-year period. This agreement, a formal cooperative research and development agreement (CRADA) between the two parties, has been finalized, and was signed in March…


Spring cleaning for DUNE at Work

Eileen Berman recently took some time to reorganize much of the information and the links in DUNE at Work. Given how dynamic DUNE is, she thought it was time for some spring cleaning. She has removed old information, made things easier to find, and streamlined the structure so that it can easily accommodate new information…
