SLAC Activities Report PEP II Ring LER (e+) 50 sextupoles with 7 TBs 316 quadrupoles need fixtures (some in straights with 4 TBs) HER (e-) 104 sextupoles just laminations 290 quadrupoless with 6 TBs The B-Factory aims to study the CP violation from the collisions between circulating electrons (maximum 12 GeV) and positions (maximum 4 GeV) up to a maximum stored current of 3 A (1.4x1014 e- or e+). The B-Factory uses the existing SLAC 2-mile-long LINAC (divided into 30 sectors) to provide the electron and positron beams at proper energies. The electron beam is directed to the high-energy (HE) bypass line through the HE extraction line at sector 10 (positrons to low-energy bypass line at sector 4). Further downstream in the Beam Switch Yard (BSY) area, the high-energy north injection transport line (HENIT) takes the electron beam into the high-energy storage ring (HER), while the low-energy south injection transport line (LESIT) takes the positron beam into the low energy storage ring (LER). LER is positioned about 1 m on top of HER in an underground tunnel of 2200-m-circumference (called the PEP-II ring). The two stored beams circulate in opposite directions and and intersect only at the center of the large BaBar detector located at the Interaction Region 2 (IR2). 10-04-04 SLAC Activities Report

In particular, the a-priori standard deviations were identical: 100 μm for distances, 50 μm for height differences, 50 μm over the distance in meters for horizontal angles, 70 μm over the distance in meters for vertical distances. 10-04-04 SLAC Activities Report

SLAC Activities Report Future SLAC Program Presented by SLAC Director Jonathan Dorfan at the 08/25/04 All Hands Meeting The Enriched Xenon Observatory is a project in particle physics aiming to detect "neutrino-less double-beta decay" using large amounts of xenon isotopically enriched in the isotope 136. Simply stated the goals of the project are: Measure effective Majorana neutrino masses with a sensitivity close to 0.01 eV Probe the Majorana nature of neutrinos. We are planning to identify the final state of the decay, a barium atom, using high resolution, single atom spectroscopy. The collaboration already has 200kg of Xenon enriched to 80% in the isotope 136 that will be employed in a prototype to be installed at WIPP. The project involves scientists from University of Alabama, Caltech, ITEP (Moscow), University of Neuchatel, SLAC, Stanford, Colorado State University, Laurentian University, UC Irvine, and Carleton University. 10-04-04 SLAC Activities Report
