We are now seeing the development of a new generation of synchrotron radiation sources, the seeded, short-wavelength Free Electron Lasers (FELs), which are capable of driving the radiation to even higher intensities, and with new capabilities such as longitudinal coherence and ultra-short pulses. The Workshop on High-harmonic Seeding for Present and Future Short Wavelength Free-Electron Lasers, ho
The status of the new injector system for MAX-lab is presented. The electron source is a thermionic RF-gun that has been designed at MAX-lab. The new injector will consist of two linac structures equipped with SLED cavities. This will produce an electron beam with an energy of 250 MeV. This beam will be recirculated in order to obtain a 500 MeV beam.
The MAX-IV linac will be used both for injection and top up into two storage rings, and as a high brightness injector for a Short Pulse Facility (SPF) and an FEL (in phase 2). 100 pC bunches of electrons are created from a 1.5 cell $-band photocathode gun and subsequently accelerated up to 3 GeV by $-band linac sections. Simulations of the dynamics of the space-charge dominated beam up to 100 MeV
Within a collaboration between MAX-lab and BESSY a one stage seeded HGHG-FEL has been set up at Maxlab. BESSY has built the undulator system consisting of a modulator, a radiator and an electromagnetic chicane. BESSY has also installed three types of diagnostic tools: optical fibres for a fast Cherenkov beam loss detection, optical fibres for absolute dose measurements via their radiation-induced
During the last few years Europe has made enormous progress towards free electron laser (FEL)-based research infrastructures. The FLASH facility [1] at DESY in Hamburg, Germany, has been in user operation since the summer of 2005; FERMI@Elettra [2] in Trieste, Italy, is under construction; the European XFEL [3] in Hamburg will start construction in summer 2008; and several other FEL projects are b
In December 1998 the FRN - The Swedish Council for Planning and Coordination of Research - decided to fund a new injector and storage ring for the MAX-laboratory. The system will consist of a 50-MeV linac, a 600-MeV booster synchrotron, and a 600-MeV storage ring for VUV undulator beamlines. The system will replace an old 100-MeV racetrack microtron and will inject the two existing storage rings:
The beam performance of the MAX II storage ring is described by computer simulations. The dynamic aperture reduction due to chromaticity correcting multipoles, higher order multipoles in quadrupoles and dipoles, alignment errors and energy deviations is calculated. The future operation of the storage ring with insertion devices is discussed. The results show that the MAX II storage ring will opera
Background: Donor-specific antibodies (DSAs) are common following lung transplantation (LuTx), yet their role in graft damage is inconclusive. Mean fluorescent intensity (MFI) is the main read-out of DSA diagnostics; however its value is often disregarded when analyzing unwanted post-transplant outcomes such as graft loss or chronic lung allograft dysfunction (CLAD). Here we aim to evaluate an MFI
An overview of the European storage ring free electron laser (FEL) project was presented. The details of initial lasing at 350 nm and 220 nm ranges were also presented. The distinguising features of the project were the use of an optical klystron to reduce power loading on the mirrors, the use of sophisticated mirror chambers and the integration of the FEL on a low emittance synchrotron radiation
The Nordic summer school in synchrotron radiation science, Advanced Research Using New X-ray Sources, was held from June 13-21, 2011 in Sweden. The school was organized by MAX-lab with economic support from the Nordic Academy for Advanced Studies (NorFA) and the Swedish German Röntgen-Ångström consortium. The school was divided into two parts. The first lecture part was held at Odengården, a cosy
Sincrotrone Trieste, collaborating with various institutions, has recently begun a 3-year project to develop a UV/VUV free-electron laser on the ELETTRA storage ring. The main features and novel technical aspects of the project are described, including the design of the optical cavity and undulator, the electron beam characteristics and a first assessment of the predicted laser performance. Prelim
Safety is of critical importance to chronic total occlusion (CTO) percutaneous coronary intervention (PCI). This global consensus statement provides guidance on how to optimise the safety of CTO) PCI, addressing the following 12 areas: 1. Set-up for safe CTO PCI; 2. Guide catheter-–associated vessel injuries; 3. Hydraulic dissection, extraplaque haematoma expansion, and aortic dissections; 4. Haem
In 2021, we published the results of genomic analyses carried out on the famous bishop of Lund, Peder Winstrup, and the mummified remains of a 5–6-month-old fetus discovered in the same burial. We concluded that the two individuals were second-degree relatives and explored the genealogy of Peder Winstrup to further understand the possible relation between them. Through this analysis, we found that
Background: Biologic effectiveness is often assessed as response, a term that eludes consistent definition. Identifying those most likely to respond in real-life has proven challenging. Objective: To explore definitions of biologic responders in adults with severe asthma and investigate patient characteristics associated with biologic response. Methods: This was a longitudinal cohort study using d
Background: Liver disease and dementia are both highly prevalent and share common pathological mechanisms. We aimed to investigate the associations between metabolic dysfunction-associated fatty liver disease (MAFLD), metabolic dysfunction-associated steatotic liver disease (MASLD) and the risk of all-cause and cause-specific dementia. Methods: We conducted a prospective study with 403,506 partici
Compacted Graphite Iron (CGI) represents a unique combination of the characteristics of grey and spheroidal cast irons, sparking significant interest over the past two decades, particularly as a favoured material in several automotive industry applications, including engine components and heavy-duty vehicle parts. Despite its growing prominence, the full potential of CGI remains underutilised, pri
