摘要:

在开发一个强子量能器与极细粒度的粒子流算法的应用程序,以测量喷流能量在未来的轻子对撞机的背景下,我们报告的小规模原型量能器的广泛测试。量热计包含多达10层的电阻板室(RPC),其具有2560个1 \times 1 cm 2的读出垫,与钢吸收板交错。这些测试包括长期宇宙射线数据采集和粒子束测量,确定了对宽带μ子以及能量在1 - 16 GeV范围内的π子和正电子的响应。详细测量室的效率作为光束强度的函数也已进行使用120 GeV的质子在不同的强度。将数据与基于GEANT 4的模拟和速率限制的分析计算进行比较。

英文摘要:

In the context of developing a hadron calorimeter with extremely fine granularity for the application of Particle Flow Algorithms to the measurement of jet energies at a future lepton collider, we report on extensive tests of a small scale prototype calorimeter. The calorimeter contained up to 10 layers of Resistive Plate Chambers (RPCs) with 2560 1 \times 1 cm2 readout pads, interleaved with steel absorber plates. The tests included both long-term Cosmic Ray data taking and measurements in particle beams, where the response to broadband muons and to pions and positrons with energies in the range of 1 - 16 GeV was established. Detailed measurements of the chambers efficiency as function of beam intensity have also been performed using 120 GeV protons at varying intensity. The data are compared to simulations based on GEANT4 and to analytical calculations of the rate limitations.
