Comprehensive handbook of activation data calculated using EASY-2003

Investigation of current and planned fusion devices, as well as conceptual power plants, requires well-validated tools to predict the activation of materials. This has led to the production of the European Activation System (EASY), which provides such a capability. The version used here, EASY-2003, is widely distributed and has been used to carry out activation calculations on a large number of materials. However, there was also a need for a comprehensive handbook of activation data that could be quickly referred to, rather than resorting to running codes. This paper discusses the process of generating, over a period of 8 months, the data for a handbook that presents the important activation data for all the naturally occurring elements from hydrogen to uranium. The main computational methods are outlined briefly, but the bulk of the paper is focused toward a description of the different ways in which the data are presented, including new presentations of activation data, called 'importance diagrams'.
