The year of 1999 is the second year of the construction of the ATLAS detector for LHC Project. Progress of construction is also noticeable for the parts that the Japanese group is responsible for construction. Meanwhile, research and developments of the data acquisition as well as physics analysis are in advanced stage. Below we list the progress for the parts that Japan is responsible ;(1) Muon trigger chambers : We have constructed about 10 prototypes of the thin-gap trigger chambers. We also tested the basic properties of these chambers. Various supporting tools were made ready for mass production. We have mastered most of steps for chamber mass-production. Concurrently, R&D of the amplifier-shaper-discrimination (ASD) LSI circuits has been completed. Then 400,000 channels of the ASD chips were successfully completed. In addition, about 30,000 pieces of the ASD boards have been finished. For the other part of the level-1 electronics system, there were wide progresses in design, prot … More otype production as well as various tests.(2) Special time-to-digital conversion chips for the muon system : The design ans prototype production has been progressed as planned. However, the input receiver circuits have shown higher power consumption which requires further design investigation.(3) Silicon semiconductor tracking detectors : We have started the mass production of the silicon sensors. Various prototypes of the silicon detector modules were developed and tested. A special robot for mounting the silicon detector modules was successfully constructed and then it was sent to the Oxford university for further use of the robot.(4) Superconducting Solenoid : the coil was successfully constructed and associated cryogenics equipments as well as its control system were constructed.(5) Data acquisition : With collaboration of CERN, we have tested a prototype even-builder using the Giga-bit Ethernet technology. Although its fundamental properties were verufied, it becomes clear that technical problems such as scalability must be further studied.(6) Physics : we have started studies of physics for LHC. Less

1999年是大型强子对撞机计划ATLAS探测器建造的第二年。对于这家日本集团负责建设的部分，建设进展也是显而易见的。同时，数据采集和物理分析的研究和开发也处于后期阶段。下面我们列出了日本负责的部件的进展情况：(1)Muon触发室：我们已经建造了大约10个薄间隙触发室的原型。我们还测试了这些腔体的基本特性。各种配套工具已经准备就绪，可以批量生产。我们已经掌握了室内式批量生产的大部分步骤。同时，完成了放大器-整形器-鉴别器(ASD)大规模集成电路电路的研发。然后，成功完成了40万个通道的ASD芯片。此外，约有3万块ASD板已经完工。对于第一级电子系统的其他部分，在设计方面有了很大的进步，Prot…更多类型的生产以及各种测试。(2)用于Muon系统的专用时间数字转换芯片：设计和原型生产已按计划进行。然而，输入接收电路已经显示出较高的功耗，这需要进一步的设计研究。(3)硅半导体跟踪探测器：我们已经开始了硅传感器的量产。开发并测试了硅探测器模块的各种原型。成功构建了硅探测器模块安装专用机器人，并将其送往牛津大学供机器人进一步使用。(4)超导螺线管：成功构建了线圈，并构建了相关的低温设备及其控制系统。(5)数据采集：与欧洲核子研究中心合作，使用千兆位以太网技术测试了一台均匀构建器原型。虽然大型强子对撞机的基本性质已经得到验证，但很明显，诸如可伸缩性等技术问题还需要进一步研究。(6)物理学：我们已经开始研究大型强子对撞机的物理学。较少
