Construction Readiness Reviews of the
Mu2e Cosmic Ray Veto System

Cosmic Ray Veto
Cosmic ray muons are a known source of potential background for experiments like Mu2e, and must be suppressed in order to achieve the sensitivity required by the experiment. Backgrounds induced by cosmic rays can be defeated by passive shielding, e.g., overburden and thick concrete shielding, and by an active veto detector whose purpose is to detect penetrating cosmic-ray muons.

The Mu2e project received CD-3 approval from the DOE on July 14, 2016. The project is finalizing its designs and preparing to start construction. External pee r reviews of key technical elements of the project are a part of this process.
