Beam Diagnostics
As soon as the first particles emerge from an ion source, the source
characteristics need to be determined. The total beam intensity, the transverse
particle distributions, the beam divergence and emittance as well as the
longitudinal parameters of the beam must be measured. This chapter provides an
overview of typical measurement methods and the instruments used, and shows the
results obtained.Comment: 12 pages, contribution to the CAS-CERN Accelerator School: Ion

Fiscal determinants of empowerment
Empowerment of local governments and citizens is a primary object of decentralization. Using the analytic lens of empowerment, the author explores the nature of decentralized governance and how this type of structure is likely to be more or less empowering. His primary concern is fiscal decentralization, specifically the association between fiscal determinants and the degree of empowerment of both citizens and local governments. The author's main argument is that both the revenue and expenditure characteristics of local public finances have an effect on the degree of empowerment. His hypothesis is that in a context of decentralized local governance, empowerment is most likely to occur when three conditions prevail: low costs of participation, largeand flexible budgets, and a high proportion of tax revenues from a local base. But these ingredients for empowerment will not necessarily produce outcomes that are progressive and pro-poor. The author contrasts the intrinsic and the instrumental approaches to empowerment, but he does not assess the impact of empowerment on instrumental outcomes. For this hypothesis to support an instrumentalist perspective on empowerment, further empirical work must be conducted.National Governance,Banks&Banking Reform,Municipal Financial Management,Public Sector Economics&Finance,Urban Economics
