Description
The next generation of long baseline neutrino experiments aims to increase proton beam power to multi-MW level and make use of massive detectors to overcome the limitation of event statistics. The DUNE experiment at LBNF will test the three neutrino flavor paradigm and directly search for CP violation by studying oscillation signatures in the high intensity νμ (anti-νμ) beam to νe (anti-νe) measured over a long baseline.
As long baseline neutrino experiments are entering a precision era, reduction in the systematic errors to the level of a few percent is necessary to attain their physics goals. The neutrino-nucleus interaction cross sections are among the most challenging sources of systematic errors. In this talk, an innovative neutrino beam research and development technique is presented to constrain the cross-section uncertainty and ensure that DUNE meets its objectives by performing time-slicing of the neutrino flux, called the ”stroboscopic approach”. By exploiting the correlation between the true neutrino energy and the measured neutrino arrival time, this technique selects different neutrino energy spectra from a wide-band neutrino beam. It uniquely allows access to true energy information at the Far detector, which is not possible from any other existing part of the DUNE experiment.
Three different thrusts are necessary for the application of stroboscopic approaches, namely: 1) creation of short (O(100ps)) proton bunch length, 2) implementation of fast timing to get equivalent time resolution in the detectors, 3) establishment of synchronization between the time at the detector and time of the bunch-by-bunch proton at the target. This talk will explain how the three different thrusts emerge from the same objective of understanding how the stroboscopic approach brings its own critical contribution to DUNE and US neutrino physics. Obtaining a better understanding of the cross sections is critical for DUNE experiment and neutrino physics as a whole and US accelerator-based neutrino beams will benefit from this novel technique.
