反应堆中微子实验

The neutrino experiment adopted new kind detector and new method using reactor's neutrino with high flux neutrino to do basic research for study neutrino as a pre-study of neutrino oscillation . This is one of biggest and longest scientific collaboration between mainland of China and Taiwan. The whole equipment of the experiment consists 200 channels of CsI(Tl) crystal detector array, semiconductor detector, electronics ,trigger system, DAQ system, cosmic ray veto and sheltering system. After determination of experiment scheme , R&D, prototype study and construction of whole system ,the data taking on side of reactor started in 2001. Both the performance of detector and physics results of neutrino magnetic moment has reached advanced level . There are 16 papers have been published and status of experiment has been reported in many scientific conferences.In fact, the experiment just start physics running .The data taking will going on several years. More physics results will be come out. We wish we can get support from NSF continually in the future.

本课题是与美国、台湾的科学家合作的科研项目。利用大通量反映堆中微子，建立不同于以前实验的CsI晶体量能器，测量MeV能区的中微子电子散射；研究中性流NC，带电流CC反应截面；证明νeνμ普适性；观测ν↑-e磁矩等。得到比较精确的结果。同时，有NC和CC之比峁┎灰览抵形⒆釉吹墓鄄庵形⒆诱竦吹姆椒ê退枰氖荩乱徊街形⒆诱竦床饬看蚝没?.
