A Soft X-ray Laser (SXL) beamline utilising FEL technology is being designed for the Short Pulse Facility (SPF) at the MAX IV Laboratory. A conceptual design study has been started following on the scientific case already prepared in collaboration between several Swedish Universities and driven by a strong (Swedish) user demand. The baseline goal of the SXL beamline is to generate intense and shor
This dissertation explores the public library’s democratic and popular educational role in a time when knowledge- and cultural institutions are affected by changes related to digitalisation. The purpose of the study is to examine how library activities, which in various ways are intended to increase individuals’ digital skills, information literacy and participation in society can be understood an
Using ethnographic data, this paper investigates the techniques used inside pubs, bars and nightclubs to solicit and sustain alcohol consumption among patrons. Focus is on venues with the majority of patrons belonging to the age group of approximately 15-35 years. The paper identifies a number of techniques, both overt and covert, including: alcohol advertising; special offers (e.g. 'Happy Hours'
BackgroundTraumatized refugees with comorbid pain report more severe posttraumatic stress disorder (PTSD), respond less well to PTSD-focused treatments, and exhibit greater disability. A mutually maintaining relationship may exist between pain and PTSD, that may be partly accounted for by depression, but no prior studies have tested this assumption in traumatized refugees.Method Self-report measur
Alongside harm avoidance, incompleteness and disgust have been proposed as important emotion-related motivators underlying the symptoms of obsessive-compulsive disorder (OCD). The aim of the present study was to investigate the validity of self-report and interview-based measures of these constructs in youth with OCD (N=100) and anxiety disorders (N=96). All participants completed self-report meas
Managing inventories, and thereby material flows, is of key importance for achieving efficient and sustainable supply chains. Green inventory management is characterized by complementing the traditional economic (cost) focus with environmental (emissions) considerations. In this chapter we identify and discuss key questions and challenges for green inventory management research. We do so by catego
The design of the 3 GeV linac for the MAX IV facility was done to provide the ability to host a future FEL in the hard X-ray as well as in the soft X-ray range. The linear accelerator, with its two bunch compressors, is now under commissioning. Through the years increasing details for the actual FEL have been discussed and presented. In parallel a steering group for the science case for a Swedish
The MAX IV facility in Lund (Sweden) is under construction and conditioning of the electron guns for the injector is ongoing. There are two guns in the injector, one thermionic gun for storage ring injection and one photocathode gun for the Short Pulse Facility. In this paper we report on the beam performance tests of the photocathode gun. The measurements were performed at the MAX IV electron gun
In the second part of 2014, the 3 GeV linac at the MAX IV laboratory will enter its commissioning stage. Equipped with two guns, the linac will act as a full energy injector for the two storage rings and at the same time provide high brightness pulses to a Short Pulse Facility (SPF). Compression in the linac is done in two double achromats with fixed R56 that relies upon the RF phase introduced en
Knowing the longitudinal phase space of an electron beam is one of the most important and crucial issues in short-pulses linacs. To achieve this task expensive and rather complicated setups (like transverse deflecting cavities) are usually implemented. The MAX IV linac is a 3GeV accelerator which will be used to inject into two rings and to drive a short pulse facility. Nevertheless, a more deep u
