摘要：

一个新的概念，球形TPC，提出了独特的优势，当低能量中微子被检测。一些应用是：a）观察的e振荡时，发射的氚源（<E e >= 14千电子伏）在一个半径为10米的球。这个项目，洗礼NOSTOS，打算给混合角13，温伯格角和一个更低的限制（< 10-12？B）中微子磁矩，b）分散在世界各地的小（半径2-4米），廉价的球体阵列将是完美的监测河外超新星，c）探测低能（pp -7 Be）太阳中微子的光谱。

英文摘要：

A new concept, the spherical TPC, presents unique advantages when low energy neutrinos are to be detected. Some of the applications are: a) observation of the e oscillation when emitted by a tritium source (<E e > = 14 keV) in a 10 m radius sphere. This project, baptized NOSTOS, intends to give the mixing angle 13, the Weinberg angle and a much lower limit (< 10-12 ?B) of the neutrino magnetic moment, b) an array of small (radius 2-4 m), cheap spheres scattered around the world would be perfect to monitor extragalactic supernovae, c) detect the spectrum of low energy (pp - 7Be) solar neutrinos.
