Research and development of next generation detectors in the e^+e^- reactions

1.金星、黄玉、艾米和SHIP通过分析特里斯坦加速器的e+e反应中获得的大量数据，发表了各种物理结果。在这些小组中举办了几次讲习班，以研究分析和模拟的方法。2.讨论了与探测器升级和伴随的分析改进有关的一些问题。我们开展了用于高光度实验的超导四极杆、精密垂直电离室(稻草室、SSD和闪烁光纤)、粒子识别设备(同步辐射探测器和跃迁辐射探测器)和高速数据处理电路的研发，并成功地使其适用于下一代实验。在加速器方面，我们研究了(A)偏振光束的可能性，(B)将AR(累积层)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PHI工厂的物理结果以及加速器的可行性进行了平行研究。与KEK加速器团队合作，我们研究了加速器技术中的各种方法，并研究了在TeV范围(JLC)实现电子-正电子对撞机的方法。在与一个强子研究小组的联合努力中，我们还开发了可以在像SSC这样的高强度环境中工作的探测器。

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.
