ASSEMBLY AND FABRICATION FACILITY RENOVATION

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 ACERT作为ESR光谱学的国家研究和开发中心，致力于先进仪器规范，设计和建造的综合计划。我们目前正在建设几个主要的光谱仪项目，如多波段外差和35 GHz脉冲仪器，光谱仪的连续波。和脉冲显微成像和控制电子学为我们改进的170和240 GHz c.w.源此外，我们正在继续升级和维修现有的ACERT光谱仪，这需要建造新的电子模块和维修旧的。升级项目包括为95 GHz脉冲光谱仪建造一个新的定时系统，为HF DEER实验和快速射频实验提供场步进驱动器。微波接收器保护开关。直到去年，我们已经能够成功地在共享实验室空间中构建仪器，但是在该空间中调试新的光谱仪和相关实验已经要求在其他地方创建新的组装设施。为了满足这一要求，我们对一个以前无人使用的储藏室进行了翻新，使其成为一个方便、舒适和全面的工作区。为了做到这一点，我们将所有缓存的项目移到校外的长期存储设施中。然后，大学被说服恢复房间，这是需要清洁，维修和油漆，沿着必要的公用设施升级的装配设施。最后，我们安装了18英尺长的半永久性工作台和大约300平方米的工作台。英尺用于存储机械和电子元件以及生产中的仪器模块的架子。该工厂配备了用于表面贴装和其他超小型组件的精密安装和再加工的工具，并为此获得了合适的双目显微镜。该设施于2004年第一季度中期开始定期使用。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. ACERT, as a national center for research and development in ESR spectroscopy, is committed to a comprehensive program of advanced instrumentation specification, design and construction. We are presently in the construction phase on several major spectrometer projects, such as multiband heterodyne and 35GHz pulsed instruments, spectrometers for c.w. and pulse microimaging and control electronics for our improved 170 and 240GHz c.w. sources. In addition, we are continuing our upgrade and repair of the existing ACERT spectrometers, which requires construction of new electronic modules and repair of old ones. Upgrade projects include construction of a new timing system for the 95GHz pulsed spectrometer, field-stepping drivers for HF DEER experiments and fast r.f. switches for microwave receiver protection. Until this past year, we have been able to successfully construct instrumentation in shared laboratory space, but the commissioning of new spectrometers and related experiments in that space has mandated the creation of a new assembly facility elsewhere. To address this requirement, we have renovated a previously unoccupied storage room in order to bring it up to the level of a convenient, comfortable and comprehensive working area. In order to do this, we removed all our cached items to an off-campus long-term storage facility. The University was then persuaded to rehabilitate the room, which was in need of cleaning, repairs, and paint, along with requisite utilities upgrades for the assembly facility. Finally, we installed 18 linear feet of semi-permanent workbenches and approximately 300 sq. ft. of shelving for storage of mechanical and electronic components, and instrument modules in production. The facility is fully equipped with tools for precision mounting and reworking of surface-mount and other sub-miniature components, and a suitable binocular microscope has also been acquired for this work. Use of this facility commenced on a regular basis in mid-1st quarter of 2004.
