The SXL (Soft X-ray Laser) project developed a conceptual design for a soft X-ray Free Electron Laser (FEL) in the 1-5 nm wavelength range, driven by the existing MAX IV 3 GeV linac. In this contribution we will focus on the FEL operation modes developed for the first phase of the project based on two different linac modes. The design work was supported by the Knut and Alice Wallenberg foundation
Echo-Enabled Harmonic Generation (EEHG) is an external seeding technique for XUV and soft X-ray Free Electron Lasers (FEL). It has recently been experimentally demonstrated and currently many facilities worldwide intend to incorporate it in user operation. The EEHG process relies on very accurate and complex transformations of electron beam phase space by means of a series of undulators coupled to
As a part of the efforts to improve the longitudinal coherence in the design of the Soft X-ray FEL (the SXL) at MAX IV, we present a possible implementation of the EEHG harmonic seeding scheme partly integrated into the second bunch compressor of the existing LINAC. A special focus is given to the effect of CSR on the resulting EEHG bunching and on how this unwanted effect might be controlled.
A Soft X-ray free electron laser (FEL) for the MAX IV Laboratory is currently in the design phase and it will use the existing 3 GeV linac. Present stability limits in the RF and the photocathode laser will affect the performance of the FEL. One of the critical elements for the design of a FEL is to have an estimation on jitter effects of the accelerator parameters on the X-ray radiation. In this
Rapporten bygger på Equalizers arbete med att utifrån normstörande aktiviteter utveckla Gullviksborgs idrottsplats i Malmö. Uppdraget utgick från Malmö fritidsförvaltning.

The encouraging results of modern breast cancer care builds on tremendous improvements in diagnostics and therapy during the 20th century. Scandinavian countries have made important footprints in the development of breast diagnostics regarding technical development of imaging, cell and tissue sampling methods and, not least, population screening with mammography. The multimodality approach in comb
During the last 100 years, musculoskeletal radiology has developed from bone-only radiography performed by everyone to a dedicated subspecialty, still secure in its origins in radiography but having expanded into all modalities of imaging. Like other subspecialties in radiology, it has become heavily dependent on cross-sectional and functional imaging, and musculoskeletal interventions play an imp
This article assesses the status of the solid waste management system (SWMS) in Karachi, the largest city of Pakistan, using the material flow analysis approach, a widely applied method in waste management (WM) studies. It involves a systematic assessment of the material flows of solid waste under the current WM system. A material flow diagram is developed to visualize the input and output waste f
V/P SPECT from 4 consecutive patients with COVID-19 suggests that ventilation and perfusion images may be applied to diagnose or exclude pulmonary embolism, verify nonsegmental diversion of perfusion from the ventilated areas (dead space ventilation) that may represent inflammation of the pulmonary vasculature, detect the reversed mismatch of poor ventilation and better preserved perfusion (shunt
Aims: The aims of this article were to examine the various meanings ascribed by three stakeholder groups – social workers, journalists and individuals with previous experience of problematic drinking – to four widely used terms in the alcohol field – alcoholism, alcohol dependence, alcohol misuse and risky drinking – and to examine how variations in the definitions of these terms correspond to spe
Antimicrobial resistance (AMR) is one of the principle public health problems in the 21st century, threatening the available treatment strategies for bacterial infections. Here, we present a human protein-lipid complex, HAMLET (human alpha-lactalbumin made lethal to tumor cells) purified from human milk as a potential therapeutic agent which has both tumoricidal and bactericidal activity. HAMLET’
The effort to address climate change cuts across a wide range of non-environmental actors and policy areas, including international economic institutions such as the Group of Twenty (G20), International Monetary Fund (IMF), and the Organisation for Economic Co-operation and Development (OECD). These institutions do not tend to address climate change so much as an environmental issue, but as an eco
This pictorial presentation of childhood aims to provide a visual depiction of the social value of the children in rural Punjabi socio-cultural context. I took these photographs in a village in south Punjab, Pakistan while doing an ethnographic inquiry about infant healthcare belief practices and the social value of the child in rural Punjab.
In this chapter, we describe the post-colonial history of higher education (HE) in Kenya and Uganda to explain why domestic doctoral education is still at a young stage in both countries. We present their national HE frameworks, and thereafter focus on local policy and practice in two public universities: Makerere University in Uganda and the University of Nairobi in Kenya. Our results are informe
Purpose – This study aims to understand master’s students’ experiences of service-learning, following their participation in a workshop with local social innovators whose activities had contributed to combating poverty in East Africa and to determine how this participation affected work on the students’ theses. The authors also explored possible gender differences in this context. Design/methodolo
Lucas, Voss, and Paller sympathize with our intentions but disagree with our findings. They argue that a relation between frequency and conceptual priming may have been obscured by methodological details in our second experiment, therefore failing to complete a bridge between conceptual priming and FN400 with name frequency as the mediator. However, renewed inspections of our experiment and a new
