数字化强子量能器的研制

Construction of the Digital Hadron Calorimeter

Kurt Francis

摘要:

粒子流算法(PFAs)已被提出作为一种方法,以提高未来的碰撞束探测器的喷流能量分辨率。PFA需要具有高粒度的量热计,以实现事件的三维成像。线性对撞机合作(CALICE)的量热仪正在开发和测试这种高度分段量热仪的原型。在这种情况下,由阿贡国家实验室领导的一个小组开发和建造了一个大型的数字强子量热仪(DHCAL)原型。DHCAL由52层组成,装有电阻板室(RPC),并与钢吸收板交错。RPC通过1 x 1 cm2焊盘以1位分辨率(数字读出)读出。DHCAL原型有大约480,000个读出通道。本讲座报告DHCAL的设计,建造和调试。DHCAL于2010年秋季安装在费米实验室试验束设施,并于2011年夏季收集数据。

英文摘要:

Particle Flow Algorithms (PFAs) have been proposed as a method of improving the jet energy resolution of future colliding beam detectors. PFAs require calorimeters with high granularity to enable three-dimensional imaging of events. The Calorimeter for the Linear Collider Collaboration (CALICE) is developing and testing prototypes of such highly segmented calorimeters. In this context, a large prototype of a Digital Hadron Calorimeter (DHCAL) was developed and constructed by a group led by Argonne National Laboratory. The DHCAL consists of 52 layers, instrumented with Resistive Plate Chambers (RPCs) and interleaved with steel absorber plates. The RPCs are read out by 1 x 1 cm2 pads with a 1-bit resolution (digital readout). The DHCAL prototype has approximately 480,000 readout channels. This talk reports on the design, construction and commissioning of the DHCAL. The DHCAL was installed at the Fermilab Test Beam Facility in fall 2010 and data was collected through the summer 2011.
