“…ASCOT has been used for a number of studies of energetic-particle effects in the boundary plasma of JET, ASDEX-Upgrade and other machines. Recent studies include the distribution and heat/particle loads of neutralbeam injected deuterons and fusion-born tritons in ASDEX upgrade, in both axisymmetric fields and including the effect of toroidal ripple [19], confinement of and heating by fusion alphas in JET for standard H-mode and internal transport-barrier plasmas, enhancement of heat and particle diffusion in JET due to toroidal ripple, and the role of hot electrons in near-divertor energy distributions [20].…”

Kinetic codes are required for quantitative simulation of edge plasmas of most tokamaks, because orbit widths can be comparable to radial scale lengths and because mean free paths can be comparable to scale lengths along the magnetic field. However, the edge presents special challenges for edge simulation, both in terms of formulation and implementation. There are two major approaches to kinetic simulation, namely particle-based and continuum-(high-dimensional fluid-) based. The edge presents challenges common to both approaches as well as ones that are unique to each approach. In this paper we review these challenges, and survey how they are being addressed in current edge kinetic simulation projects, as well as the status and accomplishments of those projects. We discuss in some detail the status and recent accomplishments of the U.S. Edge Simulation Laboratory (ESL), a project based on the continuum approach. The ESL currently consists of a main-line effort to develop a code based on high-order conservative finite-volume discretization, as well as two prototype activities, TEMPEST and EGK. These prototype codes are exploring issues attached to energy-magnetic moment and parallel velocity-magnetic moment representations, respectively, as well as physics issues associated with simulation in a steep radial gradient region and a domain that includes both open field lines and closed flux surfaces.

“…One reason to all this was that the manuals were in Danish; I had mistaken some clauses." [15] "The testing was familiar to me from the beginning of the decade 1960 in Kaapelitehdas in compiling statistical programs. Everybody believed, when coding his first program that it worked properly.…”

The Development of Software Testing in Finland 1950–2000

Abstract. The paper presents the development of software testing in Finland. This topic has received little academic attention and it is frequently forgotten. The existing publications concentrate more on the history of machines and programming languages than on the history of the development of testing. The analysis made so far proves that the problems in the early times were very different from nowadays. For example, during the 1950s and 1960s, it was difficult to get computation time for testing. Meanwhile, during the 1990s, and after that, the greatest source of problems has been the complexity and the massiveness of programs. On the other hand, it seems that the education of testing has not been sufficient until the end of 1990s. Hence, the knowledge of diverse testing methods, test automation, and outsourcing are now better than in the past. In our research, we have interviewed over fifty persons. The interviewees vary from pioneers of Finnish computing, having tens of years career, to young professionals of testing. Their selection is from Finnish universities and over twenty companies in Finland.
