Routine maintenance of Laboratory computing infrastructure will take place on the weekend of January 7. During this time, the Laboratory's website may experience service interruptions. Normal service is expected to resume by the evening of January 8.
Here we show the same region of the dipole as Figure 3; however, in this case muon decay electrons are not shown. With the decay electrons eliminated it is easier to see tracks which are due to the particles which hitting the upper and lower beam pipe surfaces. This same region is shown with the decay electron tracks turned on back in Figure 3.

One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven Science Associates, a limited-liability company founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit applied science and technology organization.
