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 an end view of the idealized quadrupole used for the toy model superimposed with the particle tracks in this region. The hits coming at negative X are from showers that are not fully contained by the toy model collimator. At positive X we find hits largely due to synchrotron radiation (from decay electrons) which passes all the way through the upstream dipoles. A more realistic quadrupole would have coil ends and these coil ends would probably have to be protected from such irradiation.

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.
