摘要

SLAC的PEP-N项目由一个极低能量小电子环(VLER)组成，它将与PEP-II的低能量3.1 GeV正电子束(LER)碰撞，产生1.1 GeV和J//spl psi/之间的质心能量。光束将正面碰撞，并将在探测器磁场中分离，该磁场是相互作用区(IR)的一部分。选择IP /spl beta/等函数来优化亮度和光束-光束调谐位移，同时保持较小的LER调谐位移。本文描述了500mev下VLER“基线”设计的晶格。

A low-energy ring lattice design for the PEP-N project

The PEP-N project at SLAC consists of a Very Low Energy small electron Ring (VLER) that will collide with the low-energy 3.1 GeV positron beam (LER) of PEP-II, producing center-of-mass energies between 1.1 GeV and the J//spl psi/. The beams will collide head-on and will be separated in the detector magnetic field which is part of the Interaction Region (IR). The IP /spl beta/ functions were chosen such as to optimize both luminosity and beam- beam tune shifts, while keeping the LER tune shifts small. This paper describes the lattice of the VLER for the 'baseline' design at 500 MeV.
