These migrations are going well, with nearly 300 staff and users migrated into Zimbra and about 250 still left to migrate. These migrations are occurring overnight, and you will receive an email around noon on the day you are scheduled to be migrated.

Students chosen for the program will have a strong academic record and a strong desire to learn about the lab's science and technology. Lab scientists, engineers and other technical managers who are interested in serving as a mentor to these high-achieving high school students and have a project, or number of projects, to be accomplished this summer, are asked to send a description of the work to be assigned to Brita Hampton, x7633, by May 1.</font></div><div><font class="Apple-style-span" face="Arial"><br></font></div><div><b><font class="Apple-style-span" face="Arial">Colloquium: From Quarks to Baseballs - The Evolution of a Physicist</font></b></div><div><font class="Apple-style-span" face="Arial">Alan Nathan, University of Illinois at Urbana-Champaign, will address some interesting and practical questions of baseball from a physics perspective. In this talk, he will discuss some of the ways that a physicist analyzes the game of baseball. The talk will be organized around two broad topics: The physics of the ball-bat collision and the aerodynamics of a baseball in flight. The goal is that all will enjoy this talk, whether your interest is physics, baseball, or the intersection between them. The colloquium will take place May 2 at 4 p.m. in the CEBAF Center auditorium.</font></div><div><font class="Apple-style-span" face="Arial"><br></font></div><div><b><font class="Apple-style-span" face="Arial">RadCon Seminar: Anticipating Radiation Damage: Calculation of Relevant Quantities</font></b></div><div><font class="Apple-style-span" face="Arial">Even non-biological matter can suffer serious consequences from radiation, both natural and artificial. Francesco Cerutti, Emerging Energy Technologies Section of the Engineering Department at CERN, will review the macroscopic quantities associated with different types of damage, such as absorbed dose, displacements per atom, high-energy hadron fluence, and silicon 1 MeV-equivalent neutron fluence. The calculation of these quantities will be discussed in the context of the Monte Carlo description of the radiation-matter interaction, with particular reference to the FLUKA code. The seminar will take place Friday, May 4 at 1:30 p.m. in CEBAF Center Room F113.</font></div><div><font class="Apple-style-span" face="Arial"><br></font></div><div><b><font class="Apple-style-span" face="Arial">Tracking Thomas at JLab</font></b></div><div><font class="Apple-style-span" face="Arial">Congratulations this week go to John Fischer, Dan Moore, Harry Fanning, Narciso Gomez, DeAnn Maddox and Karen Bartek, who were the first to correctly identify the April 18 location.
