Studies of muon-induced radioactivity at NuMI
David J. Boehnlein (Fermilab) (for the JASMIN Collaboration)
TL;DR
This study investigates muon-induced radioactivity in materials at Fermilab's NuMI beamline, comparing experimental radionuclide production data with simulations to assess implications for future high-energy physics facilities.
Contribution
It provides the first detailed measurements of radionuclide production by muons in aluminum and copper at NuMI, validated against MARS simulations.
Findings
Measured radionuclide production rates in aluminum and copper.
Good agreement between experimental data and MARS simulations.
Discussed radiological safety implications for neutrino factories and muon colliders.
Abstract
The JASMIN Collaboration has studied the production of radionuclides by muons in the muon alcoves of the NuMI beamline at Fermilab. Samples of aluminum and copper are exposed to the muon field and counted on HpGe detectors when removed to determine their content of radioactive isotopes. We compare the results to MARS simulations and discuss the radiological implications for neutrino factories and muon colliders.
