Design, development and use of the spectrometer for investigating coherent THz radiation produced by micro-bunching instabilities at Diamond Light Source

Schottky barrier diodes (SBDs) are known for their low noise, ultra-fast response and excellent sensitivity. They are often implemented as detectors in the millimetre wavelength regime. Micro-bunch instabilities (MBI) have been detected at many light sources around the world including the Diamond Light Source, UK. These MBI can result in bursts of coherent synchrotron radiation (CSR) with millimetre wavelengths. More research needs to be carried out with regards to the dynamics of MBI in order to confirm the simulations and to eventually harness the power of the CSR bursts. A single shot spectrometer has been designed and is under operation at the Diamond Light Source (DLS). It is composed of eight SBDs ranging from 33-1000 GHz. Unlike previous measurements carried out, each of the SBDs has been individually characterised thus making the results obtained comparable to simulations. In this paper, we present the assessment of each SBD in the spectrometer and the first results of the spectrometer's use in the beam

Grey literature, institutional repositories and the organisational context

A wide variety of grey literature is produced during the work carried out at a large multidisciplinary scientific research organisation. This paper examines how the grey literature may be managed and the benefits that result. Trends in Technical Reports, which have always been an important medium for transmission of knowledge, are examined, and the use of an institutional repository is advocated for the future of the medium. Other kinds of grey literature produced in research projects are also described, and again the institutional repository is seen as an important mechanism for preserving and making accessible the knowledge they embody, particularly if it is coupled with other information systems in the organisation.Includes: Conference preprint, Powerpoint presentation, Abstract and Biographical notes, Pratt student commentaryXAInternationa

API Application Programming Interface BAR Backbone Access Router

At last year’s inaugural AllHands meeting, our paper outlined the proposed development of a comprehensive and extensible network monitoring infrastructure for UK e-Science. This paper initially serves as an update, outlining the last year’s good progress in establishing an infrastructure which is already supplying tangible benefits. The paper then introduces the project’s second phase, which will see GridMon’s integration into Grid technology via compliance with the Open Grid Services Architecture. The starting point for this journey has been the development of GridMon as a web service. This, and future stages of the journey will be outlined. GridMon is not alone in developing a network monitoring system as a web and/or Grid service. Also described, as part of GridMon’s aim to be a “best of breed ” network monitoring system for UK e-Science, are ongoing collaborations such as those with the Internet2 piPEs initiative. Finally, consideration is given to new work which seeks to redress some of the widely observed imbalance between the achieved and expected network performance of end users. By building on relevant research, GridMon hopes to provide “best practice ” examples of TCP configuration, with our monitoring results showing these in a real world rather than ‘laboratory ’ context.

Grey in the Innovation Process

The research lifecycle has multiple objectives materialised as outputs, outcomes and impacts. Typical outputs are research publications (including grey literature), patents and products such as research datasets and software, many kinds of art or prototype engineering artifacts. Outcomes include patent licence income, value of a company set up to exploit the output or trained research staff. Impacts include employment creation, a commercial product that saves lives or labour or development of a new field of knowledge and research such as genomics since the 1950s. Commonly research in progress may be documented as grey literature - such as technical reports, laboratory notebooks or instructions for operating new equipment. There is a decision point when grey literature is produced. One can innovate academically. The output is peer reviewed publications; the outcomes include developing trained researchers; the impact leading to a new field of research. This route provides academic recognition. Alternatively one can innovate along the wealth-creation route. The output could be a patent; the outcome license income or a new company; the impact employment, dividends to shareholders or a new 'wonder product'. This route provides wealth and possibly improvement in the quality of life. If research is published this usually precludes following the wealth-creation route since the novel idea is now in the public domain and not protected by patent(s). Increasingly research funding and research performing organisations wish to demonstrate that the research they fund or do leads to impacts of relevance to society. Tracing of impacts back to the original research is not easy, partly because the eventual impact may not be known for many years. The key is an accurate recording of the research lifecycle including important dates so that the innovation cycle from idea to impact and back to further ideas can be demonstrated. Recent work - especially in UK in the JISC-funded MICE project - has produced a taxonomy of outputs, outcomes and impacts. In parallel an extension to CERIF (Common European Research Information Format - an EU recommendation to member states) has been developed and approved by euroCRIS. This extension re-uses typical CERIF entities of persons, projects, organisations, publications, patents, products but relates them (with temporal validity and appropriate role) to the production or utilisation of outputs, outcomes and impacts. Naturally grey literature is a key component within this model.Includes: Conference preprint, Powerpoint presentation, Abstract and Biographical notesXAInternationa

Relating Intellectual Property Products to the Corporate Context

The knowledge society demands that organizations utilise to the full the IP (intellectual property) they generate and acquire. In a context of research, development and innovation, the IP consists of products, patents and publications (in the widest sense – any stored representation of human intellect). While conventional research publications (white literature) provide much of the visible IP, the "submerged part of the iceberg" is the grey literature. With OA (Open Access) technologies the line between white and grey becomes blurred, because of accessible postprints and preprints. Significantly, white literature (and grey literature) may commonly be hyperlinked to further grey literature in the form of technical reports, procedure manuals, learning materials, software, data (in all media), communications (e.g. e- and voice-mail) etc. The hypothesis is in three parts: (a) hypermedia: hyperlinks from white (and grey) literature to the "submerged iceberg" of grey publications enriches and completes the IP of the original publication; (b) CRIS: (Current Research Information Systems) that cross-link the material to other entities in the business domain (where the business here considered is R&D) provides a context to enable the end-user to utilize more effectively the publication or collection of publications for their purpose; (c) Metadata: of high quality for controlling integrity, providing access, providing a description and managing rights is essential. At both UiB, Norway and CCLRC, UK systems have been built utilising CERIF (Common European Research Information Format which provides a data structure to match (b) above) linked with publications information. Both are based on joint research by the authors, the initial design results having been reported in GL'99 (Jeffery 1999). Both implementations have demonstrated effectiveness with enthusiastic end-users. The UiB system is targeted at providing UiB with research productivity information and uses a relational database structure extending CERIF 2000 with bibliographic entities/attributes. This allows publications to be related to people, to organizational units and to projects. At CCLRC, using relational database technology, a CERIF-based extended corporate data repository (including people, organizational units and projects) is linked with an OA eprints institutional archive, containing postprints and preprints (and also other grey publications). In each case, the relationships are annotated with role (such as author or reviewer) and start date/time, end date/time. The relationships can be many-to-many, thus a publication may have many authors each of which may have affiliations with many organizational units and projects. Each instance of organizational unit, project or person may be recursively related to another; this allows correct representation of hierarchic or network (connected graph) relationships. For both implementations the next steps involve implementing fully the formalised Dublin Core metadata proposed initially by the authors in GL'99 and since developed further by experience (Asserson and Jeffery 2004). This will provide easier syntactic (structural) interoperation and allow semantic interoperability. However, more importantly this development will allow the end-user to utilise the virtual collection, whatever the media and whatever the quality, in a knowledgeable and context-aware way.Includes: Conference preprint, Powerpoint presentation, Abstract and Biographical notes, Pratt student commentaryXAInternationa
