This action will provide funds for one faculty and one graduate student to continue a search for exotically charged particles in the highest energy particle collisions available. The experimenters use highly sensitive etchable solid state track detectors for the search of Dirac monopoles and other highly ionizing particles--magnetic charge may also be identified by its acceleration in the magnetic field of a spectrometer drift chamber. The project includes the continuation of two existing searches: one at TRISTAN (KEK Japan) and the other at the D- Zero area of the Tevatron (Fermilab). One new search at LEP (CERN) in collaboration with OPAL is an extension of the others in that it is occurring at the highest e+e- annihilations energy available. Although current theories on grand unification predict magnetic monopole masses well above any accessible at accelerators, such a search should still be carried out as experimental checks whenever better limits can be set at higher accelerator energies.

这一行动将为一名教师和一名研究生提供资金，以继续在可用的最高能量粒子碰撞中寻找奇异带电粒子。 实验人员使用高灵敏度可蚀刻固态径迹探测器来搜索狄拉克单极子和其他高电离粒子——磁荷也可以通过其在光谱仪漂移室磁场中的加速来识别。 该项目包括继续进行两项现有搜索：一项在 TRISTAN（KEK 日本），另一项在 Tevatron（费米实验室）的 D-零区域。 LEP (CERN) 与 OPAL 合作进行的一项新搜索是其他搜索的延伸，因为它是在可用的最高 e+e- 湮没能量下进行的。 尽管目前的大统一理论预测磁单极子质量远高于加速器所能达到的任何质量，但只要可以在更高的加速器能量上设置更好的限制，这种搜索仍然应该作为实验检查进行。
