AUGUST 11, 2010 PACE Status Update By Mark Zimring, Ian Hoffman and Merrian Fuller The Federal Housing Finance Agency (FHFA) regulates Fannie Mae, Freddie Mac, and the 12 Federal Home Loan Banks (the government-sponsored enterprises – GSEs). On July 6, 2010, FHFA and the Office of the Comptroller of the Currency (OCC) concluded that Property Assessed Clean Energy (PACE) 1 programs “present significant safety and soundness concerns” to the housing finance industry. 2 This statement came after a year of discussions with state and federal agencies in which PACE, a novel mechanism for financing energy efficiency and renewable energy improvements, has gone from receiving support from the White House, 3 canonization as one of Scientific American’s “World Changing Ideas” 4 and legislative adoption in 24 states to questionable relevance, at least in the residential sector. Whether PACE resumes its expansion as an innovative tool for financing energy efficiency and clean generation depends on outcomes in each of the three branches of government – discussions on a PACE pilot phase among federal agencies, litigation in federal court, and legislation in Congress – all highly uncertain. This policy brief addresses the practical impacts of these possible outcomes on existing and emerging PACE programs across the United States and potential paths forward. The work described in this Policy Brief was funded by the Department of Energy Office of Energy Efficiency and Renewable Energy, Weatherization and Intergovernmental Program under Contract No. DE-AC02-05CH11231.

联邦住房金融局(FHFA)监管房利美、房地美和12家联邦住房贷款银行(政府支持的企业——GSEs)。2010年7月6日,联邦住房金融局和货币监理署(OCC)得出结论,财产评估清洁能源(PACE) 1项目对住房金融业“存在重大的安全和稳健问题”。这一声明是在与州和联邦机构进行了一年的讨论之后发表的,在讨论中,PACE(一种为能源效率和可再生能源改进提供资金的新机制)从得到白宫的支持,被《科学美国人》列为“改变世界的想法”之一,并在24个州获得立法通过,但至少在住宅领域,它的相关性受到质疑。PACE是否会作为一种创新的能源效率和清洁发电融资工具恢复其扩张,取决于政府三个部门的结果——联邦机构之间关于PACE试点阶段的讨论、联邦法院的诉讼和国会的立法——所有这些都高度不确定。本政策简报阐述了这些可能结果对美国现有和新兴PACE项目的实际影响,以及潜在的前进道路。本政策简报中描述的工作是由能源部能源效率和可再生能源、防候化和政府间项目办公室根据合同编号资助的。DE-AC02-05CH11231。免责声明本文件是作为美国政府赞助的工作的说明而编写的。虽然本文件被认为包含正确的信息,但美国政府及其任何机构、加州大学校董会及其任何雇员均不对所披露的任何信息、设备、产品或过程的准确性、完整性或有用性作出任何明示或暗示的保证,或承担任何法律责任,或表示其使用不会侵犯私人拥有的权利。此处提及任何特定商业产品、工艺或服务的商品名称、商标、制造商或其他方式,并不一定构成或暗示其认可、推荐或受到美国政府或其任何机构或加州大学董事会的青睐。作者在此表达的观点和意见并不一定陈述或反映美国政府或其任何机构或加州大学董事会的观点和意见。类似的项目有各种各样的名称:自愿环境改善债券(VEIB)项目;能源贷款税收评估计划(ELTAPs);及能源效益/可再生能源合约评估区(E- CAD)。http://www.fhfa.gov/webfiles/15884/PACESTMT7610.pdf白宫2009年10月的改造复苏报告可在这里查阅:http://www.whitehouse.gov/assets/documents/Recovery_Through_Retrofit_Final_Report.pdf http://www.scientificamerican.com/article.cfm?id=world-changing-ideas&page=2

ELLIPSOMETRY OF SURFACE LAYERS ON LEAD AND LITHIUM 铅和锂表面层的椭偏性
Pub Date : 2011-06-15 DOI: 10.2172/6604406
Richard D. Peters
An automatic self-compensating ellipsometer was used to study anodic and corrosion films on lead exposed to sulfuric acid and lithium to water. Acid concentrations were 1.3, 3.1 and 5 M. Anodic current densities for lead ranged from 0.01 mA/cm/sup 2/ to 1.3 mA/cm/sup 2/, and mass transport conditions included free convection and forced convection. Scanning electron micrographs of the resulting surfaces were also made. A computer interpretation of ellipsometer measurements assumes the formation of up to six layers and applies a continuous mass balance. Seven to nine parameters describing the mechanism and structure of surface layers are derived by multidimensional fitting of the measurements. A solution mechanism of film formation on lead is indicated by the dependence of film properties on factors that influence the interfacial concentration of reaction products. A colloidal or polymerized phase of PbSO/sub 4/ suspended in the solution is postulated on the basis of observed mass balances and interfacial solution refractive indices. Kinetic parameters describing the corrosion of lead, evaluated from ellipsometer measurements, are consistent with those reported in the literature. The lead electrode was found to be protected from corrosion during an open circuit potential of -.6 V vs Hg/HgSO/sub 4/ (basic sulfate). Cathodic reductionmore » of PbSO/sub 4/ films terminates with the onset of H2 evolution before complete conversion of the sulfate. Changes in kinetic parameters of cathodic electrode reactions which result in preferred H2 evolution are indicated by this observation. The formation of optically absorbing films was observed in the reaction of lithium with water vapor. 44 figures, 16 tables.« less
用自动自补偿椭偏仪研究了铅在硫酸和锂在水中的阳极膜和腐蚀膜。酸浓度分别为1.3、3.1和5 m,铅的阳极电流密度为0.01 mA/cm/sup 2/ ~ 1.3 mA/cm/sup 2/,质量输运条件包括自由对流和强制对流。还对所得表面进行了扫描电子显微照片的制作。对椭偏仪测量的计算机解释假设形成多达六层,并应用连续的质量平衡。通过对测量数据的多维拟合,得到了描述表层机理和结构的7 ~ 9个参数。通过影响反应产物界面浓度的因素对膜性质的依赖性,揭示了铅溶液形成膜的机理。根据观察到的质量平衡和界面溶液折射率,假设溶液中悬浮着PbSO/sub - 4/的胶体或聚合相。描述铅腐蚀的动力学参数,通过椭偏仪测量评估,与文献报道一致。在开路电位为- 0.6时,铅电极可以防止腐蚀V vs Hg/HgSO/sub 4/(碱式硫酸盐)。在硫酸盐完全转化之前,PbSO/sub - 4/薄膜的阴极还原过程随着H2演化的开始而终止。这一观察结果表明,阴极电极反应动力学参数的变化导致H2的优先析出。在锂与水蒸气的反应中观察到光吸收膜的形成。44张图,16张表。«少

A Permanent-Magnet Microwave Ion Source for a Compact High-Yield Neutron Generator 用于紧凑型高产量中子发生器的永磁微波离子源
Pub Date : 2011-06-14 DOI: 10.1063/1.3586145
O. Waldmann
We present recent work on the development of a microwave ion source that will be used in a high-yield compact neutron generator for active interrogation applications. The sealed tube generator will be capable of producing high neutron yields, 5x1011 n/s for D-T and ~;;1x1010 n/s for D-D reactions, while remaining transportable. We constructed a microwave ion source (2.45 GHz) with permanent magnets to provide the magnetic field strength of 87.5 mT necessary for satisfying the electron cyclotron resonance (ECR) condition. Microwave ion sources can produce high extracted beam currents at the low gas pressures required for sealed tube operation and at lower power levels than previously used RF-driven ion sources. A 100 mA deuterium/tritium beam will be extracted through a large slit (60x6 mm2) to spread the beam power over a larger target area. This paper describes the design of the permanent-magnet microwave ion source and discusses the impact of the magnetic field design on the source performance. The required equivalent proton beam current density of 40 mA/cm2 was extracted at a moderate microwave power of 400 W with an optimized magnetic field.
我们介绍了一种微波离子源的最新开发工作,该源将用于用于主动询问应用的高产量紧凑型中子发生器。密封管发生器将能够产生高中子产量,D-T反应为5 × 1011 n/s, D-D反应为1 × 1010 n/s,同时保持可运输性。我们用永磁体构建了一个2.45 GHz的微波离子源,以提供87.5 mT的磁场强度来满足电子回旋共振(ECR)条件。微波离子源可以在密封管操作所需的低气压和比以前使用的rf驱动离子源更低的功率水平下产生高提取光束电流。100毫安的氘/氚光束将通过一个大狭缝(60x6平方毫米)被提取出来,将光束功率分散到更大的目标区域。本文介绍了永磁微波离子源的设计,讨论了磁场设计对源性能的影响。在400 W的中等微波功率和优化磁场条件下,提取出所需的等效质子束电流密度为40 mA/cm2。

The magnetocrystalline anisotropy energy (MAE) of the Co atoms, which is the main source of the magnetocrystalline anisotropy of the CoPt magnetic grains, has beendetermined directly from these element-specific hysteresis loops.

摘要利用角度相关的x射线磁圆二色性,我们测量了掺杂Co 80pt 20薄膜col2,3边缘的磁滞回线。钴原子的磁晶各向异性能量(MAE)是CoPt磁性颗粒磁晶各向异性的主要来源,直接由这些元素特有的磁滞回线确定。当氧化物体积分数(OVF)由16.6%增加到20.7%时,Co MAE由0.117 meV/原子降低到0.076 meV/原子。虽然较大的OVF有助于实现较小的晶粒尺寸,但它可以减少磁晶各向异性,这一点从直接Co - MAE测量中得到了明确的证明。我们的研究结果表明,OVF在19.1%至20.7%之间的seco 80 p20氧化膜是高密度磁记录的合适候选材料。现地址:荷兰恩斯赫德7500 AE邮编217号特温特大学MESA+纳米技术研究所。通讯作者:yx2@ohm.york.ac.uk

The magnetocrystalline anisotropy energy (MAE) of the Co atoms, which is the main source of the magnetocrystalline anisotropy of the CoPt magnetic grains, has beendetermined directly from these element-specific hysteresis loops. When the oxide volume fraction (OVF) is increased from 16.6% to 20.7%, the Co MAE has been found to decrease from 0.117 meV/atom to 0.076 meV/atom.While a larger OVF helps to achieve a smaller grain size, it reduces the magnetocrystalline anisotropyas demonstrated unambiguously from the direct Co MAE measurements.Our results suggest that thoseCo 80 Pt 20 :oxide films with OVF between 19.1% and20.7%aresuitable candidates for high-density magnetic recording.
