Basic Scientific Cooperation for Visits and Assignments of Scientific and Technical Personnel

The purpose of this CRADA is to establish the procedures, standards and policies for visits and assignments of scientific and technical personnel, including student exchanges, between Fermi National Accelerator Laboratory (Fermilab) and the Instituto de Física Corpuscular (IFIC) to foster cooperation in the area of particle and astroparticle physics and cosmology. The CRADA supports the basic and fundamental research to build collaboration with international partners that can help both share the cost of large-scale projects as well as add valuable capabilities and expertise that may not exist within the U.S.

Light Yield Calibration in MicroBooNE

The MicroBooNE detector is a Liquid Argon Time Projection Chamber (LArTPC) located along the Booster Neutrino Beam (BNB) at Fermilab. Its primary physics goal is to contribute to addressing the elusive short-baseline MiniBooNE low energy excess. MicroBooNE records and utilises both the ionisation charge and scintillation light produced inside the TPC to select and reconstruct neutrino interactions. The scintillation light collected using a plane of PhotoMultiplier Tubes (PMTs) is also used for accurate event timing and cosmic muon rejection with the latter being an important background for detectors, such as MicroBooNE, located on the surface. A good understanding of light modeling and its related systematic uncertainties is crucial to evaluate their impact on physics analyses. The experience acquired from MicroBooNE regarding how the stability of the scintillation light behaves and evolves during the 5 years of the primary physics run will be discussed as well as the calibration method used. This experience will help with understanding the physics of scintillation light in LArTPCs for the future long-running Short-Baseline Neutrino (SBN) and Deep Underground Neutrino Experiment (DUNE) programs.
