Study for Data Acquisition System and Computer Simulation for Super High Energy Hadron Collider (SSC)

这项研究是为了准备基本粒子物理学的研究，如使用超导超级对撞机（SSC）在超高能量下寻找希格斯粒子。1989年成立了一个国际实验小组SDC。日本物理学家打算大规模参加SDC。该项目延续了10多年的探测器研发 * 探测器设计 * 建造 * 物理数据采集 * 数据分析的顺序。我们刚刚通过了探测器设计阶段。为了使物理实验切实可行，必须在读出电子学、数据采集、计算机包括计算机仿真等方面采用高技术。本研究的目的是在日美高能物理合作的支持下，促进数据采集/计算机相关学科的研发和设计工作。在本研究的支持下，取得的主要成果有：（1）SDC探测器的总体设计;（2）针对特定探测器，如硅跟踪器、吸管跟踪器等的超大规模集成电路（VLSI）的研制，特别是日本课题组提出了一种利用CMOS存储技术实现时间数字化的新电路思想--时间存储单元（TMC）。(3)（4）建立碰撞事件和探测器元件的通用模拟程序;（5）SSC实验用离线计算系统的概念设计。

This research is to prepare the study of elementary particle physics such as search for Higgs particles at super high energies using Superconducting Super Collider (SSC). An international experimental team SDC was formed in 1989. Japanese physicists intend to participate SDC in large scale. The project extends over 10 years with the sequence of detector R&D* detector design* construction* physics data taking* data analysis. We just passed the stage of detector design. In order to make the physics experiment feasible, a high technology must be employed in readout electronics, data acquisition, computers including computer simulation. This research aims to promote the R&D and design efforts in the data-acquisition/computer related subjects in conjunction with the support from the Japan-US cooperation in high-energy physics. The achievements under the support of the present research are :(1) Overall design of SDC detector,(2) Development of VLSI for specific detectors, such as silicon and straw trackers, Especially TMC (time memory cell), a new circuit idea of time digitization using CMOS memory technology, was developed and tested by Japanese group.(3) Conceptual design of the event builder with high speed switching devices,(4) Creation of common simulation program for collider events and detector elements and(5) Conceptual design of the off-line computing system for experiment at SSC.
