Near Detector Task Force achieves goal

The Near Detector Task Force is getting ready to submit its final report.
“We have reached our goal,” said Steve Brice, the task force leader. “We have completed a set of four run-throughs of the analysis chain, each more sophisticated than the previous… The collaboration can now use these results to inform the near detector design…”


Life in Lead, SD: what to expect

About a hundred members of the community around Lead, SD gathered last Monday evening in the Lead/Deadwood High School auditorium to learn more about LBNF and DUNE, the activities that will be taking place in and around SURF to prepare for and support these projects, and the changes the community will notice as construction ramps up…


Clash detection

As DUNE progresses from working groups into consortia responsible for the design and construction of actual detector elements — consortia that are distributed around the globe — how does the project verify that the detector elements will fit together in the cryostats and that the detector modules will work within the design and constraints of the conventional facilities that support the experiment? The answer is a set of integrated 3D models…


Happy 2nd Birthday, LBNF!

As the clock struck 4:55 p.m. in Batavia, IL on January 8, 2015, after a 2014 buzzing with talk about combining LBNE and LBNO, then-LBNE Project Director Jim Strait and Project Manager Elaine McCluskey declared the end of LBNE… Less than a month later, Marzio Nessi, Elaine and two others had sketched out a basic layout for underground detector spaces at SURF, a layout that would evolve into the current configuration of the LBNF far site conventional facilities and cryostats for DUNE…


Testing readout both cold and warm

The cold electronics team at Brookhaven received the first prototype cold ADC ASIC in mid-January and tested a preliminary sample at both room and liquid nitrogen temperatures… Teams at Brookhaven and Fermilab are testing several prototype Warm Interface Boards…


Getting the high voltage right

As DUNE pioneers one technology after another, each one requires validation. Since high voltage issues in liquid argon are not fully understood, work is advancing on a setup at Fermilab to evaluate the ProtoDUNE-SP high voltage design…


Algorithms for the machine-learning era

LArTPC detectors produce image-like projections of particle trajectories, but due to the very large sizes of these images, current reconstruction approaches have only been able to process strongly reduced representations of the data… Exploration of the full potential of LArTPC detectors, therefore, requires cutting-edge computing technologies, such as deep neural networks…


Monitoring data quality and detector status

Experiments are only as good as their data. Online monitoring (OM) and prompt processing systems will ensure that the ProtoDUNEs, and eventually DUNE, can keep nearly real-time track of data quality and detector status, and fix any problems quickly, giving the detectors more time to accumulate valuable data…


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…
