Tevatron加速器物理和操作要点

Tevatron accelerator physics and operation highlights

A. Valishev

摘要:

Tevatron对撞机的性能在运行II期间持续增长,峰值亮度达到4 \times 1032 cm-2 s-1,每周积分率超过70 pb-1。本报告介绍了最重要的进展,有助于这一性能的改善,包括光束动力学建模,精密光学测量和稳定性控制,低β挤压期间的准直实施的审查。提出了光度积分优化的算法,并讨论了高光度运行的经验教训。本文介绍了在Tevatron上进行的新的加速器物理概念的研究,如采用晶体准直器和空心电子束的准直技术,以及束-束效应的补偿。

英文摘要:

The performance of the Tevatron collider demonstrated continuous growth over the course of Run II, with the peak luminosity reaching 4\times1032 cm-2 s-1, and the weekly integration rate exceeding 70 pb-1. This report presents a review of the most important advances that contributed to this performance improvement, including beam dynamics modeling, precision optics measurements and stability control, implementation of collimation during low-beta squeeze. Algorithms employed for optimization of the luminosity integration are presented and the lessons learned from high-luminosity operation are discussed. Studies of novel accelerator physics concepts at the Tevatron are described, such as the collimation techniques using crystal collimator and hollow electron beam, and compensation of beam-beam effects.
