The Tevatron broke Fermilab’s initial luminosity record on Thursday, April 28, when store number 8700 achieved an average initial luminosity of 405.25 µb-1/s. Then on Friday, April 29, an even higher average initial luminosity value of 416.61 µb-1/s was achieved by store number 8701. These stores broke our previous record of 402.4 µb-1/s, which was set about a year ago, on April 16, 2010. The unit of measurement µb-1/s is roughly equivalent to 70,000 proton-antiproton collisions per second.

Members of the Fermilab community are invited to attend a Brown Bag Seminar on bicycle commuting, hosted by the Fermilab Traffic Safety Subcommittee. The seminar, titled “Bicycle Safety, Road Sharing and Greenhouse Gas Reduction,” will be presented by Officer Emil Jensen, Batavia Police Department, and Eric Mieland, Fermilab ES&H, and will take place from noon to 12:45 p.m. on Tuesday, May 3, in Wilson Hall Curia II.

April 27-29

– Three stores provided ~43.25 hours of luminosity – Tevatron RF station 4 repaired in between stores – Operators tuned on the I-Source output – Store 8700 set a new record with a luminosity of 405.25E30 – Operators monitored the conditioning for a New Muon Lab coupler cavity Read the Current Accelerator Update Read the Early Bird Report View the Tevatron Luminosity Charts

Roy Parker, a cashier in the Accounting Department, is retiring today after more than 27 years of dedicated service with the laboratory. His colleagues wish him the best of luck.

This month, the Wellness Office will sponsor the following free events: Employee Health & Fitness Day from 11 a.m. – 1:30 p.m. on Wednesday, May 18, in the Main Ring. T-shirts, pedometers, yogurt cones and more will be available for participants. Use this as your kickoff to the 10,000 Steps-a-Day walking program. Qigong, Mindfulness & Tai Chi Easy® for Stress Reduction classes from 7 – 8 a.m. on Wednesdays in Ramsey Auditorium; and from noon – 12:45 p.m. on Fridays…

The Tevatron broke Fermilab’s initial luminosity record on Thursday, April 28. That afternoon, store number 8700 achieved an average initial luminosity of 405.25 µb^-1/s. This broke our previous record of 402.4 µb^-1/s, which was set on April 16, 2010. The unit of measurement µb^-1/s is roughly equivalent to 70,000 proton-antiproton collisions per second.

Join Fermilab at 12:30 p.m. on Wednesday, May 4, to learn about muons, including what they are, how we study them and what they might tell us. In his talk, titled "The magic of muons" scientist Chris Polly will explain how future Fermilab experiments will exploit the unique characteristics of these little particles to study the big picture of particle physics.  The lecture is free and open to the public. It will take place in Ramsey Auditorium. No registration is…
