Latest Tevatron store set two new records The latest store of protons and antiprotons in the Tevatron collider has been the best that the Tevatron has seen so far. Accelerator experts established store #2328 on Thursday morning, March 20, at 8:53 a.m., producing collisions at a new record rate of 40.7E30 that was slightly higher than the record for initial peak luminosity set by a store four days earlier. But then store #2328 crashed a second record after producing collisions for more than 21 hours. When operators terminated the store on Friday morning at 6:17 a.m., the store had produced the most collisions for a single store. Called the integrated luminosity of a store, operators achieved 1713 inverse nanobarns, or an average of 80 inverse nanobarns per hour. The previous record for Collider Run II, which began in 2001, was 1601 inverse nanobarns, or about 72 per hour. The best mark of Collider Run I, which took place from 1992 to 1996, was 815 inverse nanobarns, with a production of 45 per hour.
