在2008-2009年的运行中，蟹腰碰撞方案已经在e（+）e（-）弗拉斯卡蒂对撞机上成功地进行了测试：光度的增加与预测一致，而背景仍然是可持续的。在DA Phi NE加速器团队用于引导这台新机器并提高其性能的各种输入中，LUMI探测器提供了关键的在线信息，绝对亮度和背景水平测量：Bhabha量热计和两个伽马韧致辐射正比计数器。本文重点介绍了这种实验装置所取得的成果，在另一篇文章中有详细描述。(C)2010 Elsevier B. V.保留所有权利。
The crab waist collision scheme has been successfully tested at the e(+)e(-) Frascati collider during the 2008-2009 runs: the gain in luminosity is consistent with the predictions while the background remains sustainable. Among the various inputs used by the DA Phi NE accelerator team to steer this new machine and improve its performances, key online information, absolute luminosity and background level measurements, has been provided by the LUMI detectors: a Bhabha calorimeter and two gamma bremsstrahlung proportional counters. This paper focuses on the results achieved with this experimental setup, described in details in another article. (C) 2010 Elsevier B.V. All rights reserved.
