CALICE Si-W电磁量能器物理样机对电子的响应

Response of the CALICE Si-W Electromagnetic Calorimeter Physics Prototype to Electrons

CALICE Collaboration

摘要:

2006年夏季和秋季,在欧洲核子研究中心安装并测试了用于国际直线对撞机(ILC)探测器的原型硅钨电磁量能器(ECAL)。探测器有6480个尺寸为1 × 1 cm ^2的硅垫。数据收集与电子束的能量范围为6至45 GeV。本文所描述的分析集中在电磁簇射重建和表征ECAL响应电子的能量分辨率和线性度。该探测器在约1%水平内呈线性,相对能量分辨率为(16.6 +- 0.1)/ \sqrt{E(GeV})+ 1.1 +- 0.1(%)。空间均匀性和时间稳定性的ECAL也解决了。

英文摘要:

A prototype Silicon-Tungsten electromagnetic calorimeter (ECAL) for an International Linear Collider (ILC) detector was installed and tested during summer and autumn 2006 at CERN. The detector had 6480 silicon pads of dimension 1x1 cm^2. Data were collected with electron beams in the energy range 6 to 45 GeV. The analysis described in this paper focuses on electromagnetic shower reconstruction and characterises the ECAL response to electrons in terms of energy resolution and linearity. The detector is linear to within approximately the 1% level and has a relative energy resolution of (16.6 +- 0.1)/ \sqrt{E(GeV}) + 1.1 +- 0.1 (%). The spatial uniformity and the time stability of the ECAL are also addressed.
