TOTEM:总截面和亮度测量的前景

TOTEM: Prospects for Total Cross-Section and Luminosity Measurements

M. Deile

摘要:

在距离IP 5 147米处安装了T1望远镜和Roman Pot站后,TOTEM实验的探测器装置在2010/2011年冬季技术停留期间完成。在β * = 90 m的专用束流光学调试后,将在即将到来的2011年运行季节中首次测量总pp截面sigma_tot和同时测量亮度L。对于sigma_tot和L,所设想的精度分别为3%和4%。具有β * ~ 1 km的最终束流光学配置稍后将不确定性降低到1%水平。

英文摘要:

With the installation of the T1 telescope and the Roman Pot stations at 147 m from IP5, the detector apparatus of the TOTEM experiment has been completed during the technical stop in winter 2010/2011. After the commissioning of the dedicated beam optics with beta* = 90 m, a first measurement of the total pp cross-section sigma_tot and -- simultaneously -- the luminosity L will be possible in the upcoming running season 2011. The precision envisaged is 3 % and 4 % for sigma_tot and L, respectively. An ultimate beam optics configuration with beta* ~ 1 km will later reduce the uncertainty to the 1 % level.
