The CCLRC e-Science Centre is working on a number of UK e-Research projects supporting access to large research facilities such as the neutron spallation source (ISIS), the Synchrotron Radiation Source (SRS) and the Central Laser Facility (CLF) and the new synchroton light source, Diamond in addition to the National Grid Service and the HPCx supercomputing facility. The aim of this work is to create an Integrated e-Science Environment for CCLRC. A clear requirement of facility users is to provide seamless access and integration of these resources. This can be done by developing portal interfaces for each facility or project exposing their services as portlets for reuse between the different portal frameworks and CCLRC projects. This paper outlines the benefit of using portal frameworks and portlets to meet this goal with a Service Oriented Architecture designed to complement desktop tools. An example is given of the portal services being provided for the National Grid Service (NGS) and e-HTPX portals, which include computational and data Grid production resources for research.
