The European Spallation Source (ESS) is a neutron-scattering facility funded and supported in collaboration with 17 European countries in Lund, Sweden. Cryogenic cooling at ESS is vital particularly for the linear accelerator, the hydrogen target moderators, a test stand for cryomodules, the neutron instruments and their sample environments. The paper will focus on specific process design criteria

Exercises 1. Attosecond pulse trains (a) We consider odd harmonics of a fundamental laser field at 800 nm between 21 and 37 and assume that they are in phase at , and that they have the same amplitude. Calculate the temporal intensity resulting from the superposition of the harmonic, and estimate the duration of the individual pulses. Note: The duration of a pulse with the form is given approximat

Global steel production is currently dependent on coal and capital-intensive production facilities with long economic lifetimes. While the Paris Agreement means carbon neutrality must be reached globally by 2050–2070, with negative emissions thereafter, coal-based steel production today accounts for around 8% of global energy-related CO2 emissions. Its production may stabilize or even decline in i

Coherent harmonic generation can be obtained by means of frequency up-conversion of a high-power external laser focused into the first undulator of an optical klystron. The standard configuration is based on a single-pass device, where the seed laser is synchronized with an electron beam entering the first undulator of the optical klystron after being accelerated using a linear accelerator. As an

Popular ScienceThe growing need for green processes in industry makes scientists design and develop processes that are more energy efficient than current processes. Naturally, some reactions require a high energy and long time to occur. This will cause high energy consumption and, typically, even more waste production. Therefore, many efforts have been done to design materials that can help to chaThe research work that I describe in my thesis deals with three different heterogenisation approaches for synthesising a heterogeneous transition metal catalyst used for direct C-H activation reactions. The three heterogenisation approaches considered in my research are: (1) heterogenisation of a molecular catalyst on a polymer support using covalent bonds, (2) heterogenisation of a catalyst on a

The empirical focus of this article is technological innovation activities in the emerging field of fuel cells and related hydrogen technology in Norway from 1990 to 2002. In this period, four comparatively large-scale research and development projects and a number of smaller projects aimed at development of fuel cells technology were undertaken, resulting in many inventions that were subsequently

This paper is an attempt to link the concept of Existential Sustainability to research within the field of electrical power systems modelling. This is specifically done in the context of electrification and the energy transition. In extension, this implies a connection between the fields of humanities and technology.

The need for low-carbon transitions in the industrial sector is increasingly recognised by governments and industry. However, radical pathways for reaching near-zero emissions in the energy intensive basic materials industry are still relatively unexplored. Most studies focus on mitigation options that lead to marginal emission reductions, e.g., energy and materials efficiency improvements and som

Inverted perovskite solar cells (IPSCs) have emerged as promising photovoltaic technologies due to excellent photoelectric properties and solution processing advantages. However, the traditional preparation process based on inert atmosphere annealing of perovskite films faces key challenges, including high energy consumption, strict crystallization control, and the presence of stresses. The study

A set of measurement with moveable aperture restrictions, also called scrapers, has been carried out at MAX II (Nucl. Instr. and Meth. A 343 (1994) 644), the 1.5GeV electron storage ring at MAX-lab, Lund, Sweden. The measurements with scrapers in MAX 11 have shown to give a number of useful results, such as the vertical and horizontal acceptance, which are 7.4 x 10(-6) and 9.6 x 10-6 m, respective
