摘要：

自2008年2月以来，在e+ e-Frascati DAFNE加速器复合体进行的蟹腰碰撞计划的测试需要快速准确地测量绝对光度，以及对背景条件的全面表征。在2007年底至2008年初的相互作用点附近，设计、测试并安装了三种不同的监测器，一种巴巴量热计、一种巴巴GEM跟踪器和一种伽马韧致辐射正比计数器。在本文中，我们描述了这些探测器，并介绍了他们在2008年和2009年DAFNE运行在各种操作条件下的性能。

英文摘要：

The test of the crab waist collision scheme, undergoing at the e+e- Frascati DAFNE accelerator complex since February 2008, requires a fast and accurate measurement of the absolute luminosity, as well as a full characterization of the background conditions. Three different monitors, a Bhabha calorimeter, a Bhabha GEM tracker and a gamma bremsstrahlung proportional counter have been designed, tested and installed around the interaction point end of 2007-beginning of 2008. In this paper, we describe these detectors and present their performances in various operation conditions during the 2008 and 2009 DAFNE runs.
