1. A variety of physics results have been published by VENUS, TOPAZ, AMY and SHIP by analyzing a vast amount of data obtained in the e+e- reactions at the TRISTAN accelerator. Several workshops among the groups have been held to study methods of analysis and simulation. Some issues concerning the upgrade of the detectors and accompanying analysis improvements were addressed.2. We have carried out R &, D of supercondeucting quadrupoles for high luminosity experiments, precision vertx chambers(straw chamber, SSD, and scintillation fiber), particle identification devices(synchrotron radiation detector and transition radiation detector), and high speed data processing circuits and have succeeded to make them feasible for the next generation experiments.3. On the accelerator side, we have examined (a) possibility of the polarized beam, (b) upgrade of AR(accumulation rind) to high luminosity accelerator, (c) possibility of an asymmetric collider.4. A parallel research on the physics outcome as well as the accelerator feasibility of a B-factory and phi-factory have been carried out.5. In collaboration with KEK accelerator teams, we looked into various approaches in the accelerator technology and studied ways to realize an electron-positron collider in the Tev range(JLC).6. In a joint effort with a hadron study group, we also developed detectors that can work in high intensity environments like SSC.

1. VENUS、黄玉、AMY和SHIP等机构通过分析TRISTAN加速器上e+e-反应的大量数据，发表了各种各样的物理结果。在各小组之间举办了几次讲习班，研究分析和模拟方法。讨论了有关探测器升级和相应的分析改进的一些问题。开展了高亮度实验用超导四极杆、精密垂直电离室（吸管室、SSD和闪烁光纤）、粒子鉴别装置（同步辐射探测器和渡越辐射探测器）和高速数据处理电路的研制，并成功地为下一代实验提供了可行性.在加速器方面，我们已经研究了（a）偏振束的可能性，（B）AR（积累皮）升级为高亮度加速器，（c）非对称对撞机的可能性。对B工厂和φ工厂的物理结果以及加速器的可行性进行了平行研究。在与KEK加速器团队的合作中，我们研究了加速器技术的各种方法，并研究了实现Tev范围内的正负电子对撞机（JLC）的方法。6.在与强子研究小组的共同努力下，我们还开发了可以在SSC等高强度环境中工作的探测器。
