Electrostatic charging due to cosmic rays and other uncontrollable processes can degrade the performance of components of high precision instrumentation. This has recently been recognized as a significant issue for the ultra-high-precision measurements of the Laser Interferometer Gravitational-wave Observatory (LIGO). However, it has been studied over a longer period by other gravitational physicists such as those working on the Laser Interferometer Space Antenna (LISA), Gravity Probe B, and high precision laboratory experiments. This award supports a workshop to be held at the Massachusetts Institute of Technology on July 26 - 27, 2007 where LIGO scientists from around the world will meet with scientists working on LISA, Gravity Probe B, and other gravitational precision measurements to share knowledge on electrostatic charging phenomenology and methods for mitigation.

由于宇宙射线和其他不可控过程引起的静电充电会降低高精度仪器部件的性能。最近，这被认为是激光干涉仪引力波天文台（LIGO）超高精度测量的一个重要问题。然而，它已经被其他引力物理学家研究了很长一段时间，比如那些从事激光干涉仪空间天线（LISA）、重力探测器B和高精度实验室实验的人。该奖项支持将于2007年7月26日至27日在麻省理工学院举行的研讨会，来自世界各地的LIGO科学家将与从事LISA、重力探测器B和其他重力精密测量的科学家会面，分享关于静电充电现象和缓解方法的知识。
