1. We have examined the topology and the functions for the fast data acquisition system such as the one needed in the electronpositron collider experiment. We found that the FASTBUS standard proposed by the US-NIM committee meets our requirement.2. The data acquisition system for TRISTAN experiments has been studied in detail and it has been found that the data tansfer rate should be greater than 8 MB/s and that the event rate should be reduced, by a trigger logic, to a few per second.3. We have developed hardwares, in accordance with the item 2 above, which enable fast data transfer and triggering :i) A simplified version of a FASTBUS Segment Interconnect.ii) A FASTBUS Simplex Segment Interconnect.iii) A FASTBUS Processor Interface for Eight Bit Microcomputers.iv) A Track Finding Module for Drift Chambers.v) A First-Level Trigger decision Module.We have designed , constructed and tested the electronics modules stated above and found that they function as we expected.4. The softwares have been developed for driving and testing the FASTBUS modules. They are included in a standard library which can be easily used under the operation system CP/M .5. A work-shop on data acquisition system has been held at Hiroshima University. Based on the present study, together with the discussions among the contributors, it has been concluded that the FASTBUS is most appropriately used to process and transfer the digital data to the online computer and that another type of data bus is worth examining for the part where the analog data is involved.

1.研究了正负电子对撞机实验中所需要的快速数据采集系统的拓扑结构和功能。我们发现，美国-NIM委员会提出的FASTBUS标准符合我们的要求。对用于特里斯坦实验的数据采集系统进行了详细的研究，发现数据传输速率应大于8MB/S，并且应通过触发逻辑将事件速率降低到每秒几个。根据上述第二项，我们已经开发了硬件，能够实现快速数据传输和触发：i)FASTBUS段互连的简化版本。ii)FASTBUS单工段互连。iii)用于八位微型计算机的FASTBus处理器接口。iv)漂移室的轨迹发现模块。v)第一级触发判决模块。我们设计、构造和测试了上述电子模块，发现它们的功能符合我们的预期。开发了FASTBUS模块的驱动和测试软件。它们包含在一个标准库中，可以很容易地在CP/M.5操作系统下使用。在广岛大学举办了一个关于数据采集系统的工作坊。在本研究的基础上，结合贡献者之间的讨论，得出结论：FASTBUS最适合用于处理数字数据并将其传输到在线计算机，对于涉及模拟数据的部分，另一种类型的数据总线值得研究。
