This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The original prototype PAD built by Gruner`s group was tested at CHESS at station B1 with diffraction images from aluminum wire. The test was very successful, but we only had enough flux through 150 x 900 micron aperture to achieve 10 millisecond images. The detector was at room temperature and high background noise prevented us from taking shorter exposures (along with the limited flux through the slit). This second detector is in the development stage and the Gruner group is testing the detector under X-ray exposure at the macromolecular stations taking macromolecular data.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目和 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 中心，不一定是研究者的机构。 Gruner 小组制造的原始原型 PAD 在 B1 站的 CHESS 上使用铝线衍射图像进行了测试。 测试非常成功，但我们只有足够的通量通过 150 x 900 微米孔径才能获得 10 毫秒的图像。 探测器处于室温下，高背景噪音使我们无法进行较短的曝光（以及通过狭缝的通量有限）。 第二个探测器正处于开发阶段，格鲁纳小组正在大分子站的 X 射线照射下测试该探测器，获取大分子数据。
