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 a cross section of the dipole with the additional shield for stopping synchrotron radiation generated by the decay electrons. The shield concept is outlined in Figure 8. Here we note that the shield used in the toy model is taken to be quite thick in order to ensure that very little energy can leak through. Given the observed minimal photon penetration of the shield we anticipate that it could be made much thinner. In future studies we intend to investigate a baffled shield configuration, with integrated channels, that could be useful for vacuum pumping.

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.
