Vi vet att laddade partiklar sänder ut elektromagnetisk strålning då de tvingas följa en krökt bana. Denna strålning kallas synkrotronstrålning, och upptäcktes i mitten av 1900-talet. Sedan dess har denna typ av strålning funnit tillämpningar inom flera forskningsområden såsom kemi, biologi, medicin och materialvetenskap. För att uppfylla de växande kraven på vissa strålningsegenskaper, är partike
17 april 2026 12:00 till 13:00 | From medical imaging to drug discovery, AI is reshaping biomedical research. But it also requires significant energy and resources. Join this panel during Sustainability Week to explore AI’s footprint, its potential, and what responsible practice could look like in Sweden. During Sustainability Week in Lund, the Sustainability Committee at Lund Stem Cell Center inv

Coherent radiation from a relativistic electron beam is a valuable way to overcome the present limitations of conventional lasers and synchrotron radiation light sources. The typical scheme has electrons, directly from a linac, in a single-pass interaction with a laser pulse in the presence of a static undulator magnetic field. We demonstrate that a storage-ring free-electron laser can also achiev
Longitudinal coupled-bunch instabilities are driven by monopole higher-order modes (HOMs) in the active and passive radio-frequency (rf) cavities at the MAX IV 3 GeV electron storage ring. By combining different beam and rf-based techniques, we have performed a systematic survey of the properties of these resonant modes as a function of cavity temperatures and fundamental mode frequency.

Popular Abstract in English The word “combustion” describes a number of physical and chemical processes, whose common characteristic is an interaction between fuel and oxygen and their subsequent transformation into products, such as CO2 and water. Even though the process is often described as a single chemical reaction between fuel and oxygen, in reality, their chemical transformation requires maThe laminar burning velocity and the flame structure are common targets for combustion studies aimed at detailed kinetic model development. In the present work, fuels relevant to hydrogen combustion were considered. The laminar burning velocity of rich and lean hydrogen flames was studied experimentally and numerically, including its pressure dependence in rich mixtures and temperature dependence
A novel atmospheric pressure non-thermal plasma, i.e., rotating gliding arc (RGA), is developed to upgrade coal bed methane (CBM) into hydrogen and carbon aerosol simultaneously. CH4 is used as a CBM surrogate. In present work, the V-I characteristics of RGA discharge in CH4 conversion are monitored with different gases (N2, Ar and CO2) as carrier gas, while the active species (such as OH, CH, CN,
In a storage-ring free-electron laser (FEL), the onset and growth of intra-cavity power at the resonator wavelength can be naturally accompanied by coherent emission at higher harmonics. Contrary to what happens in singlepass linac-based devices, the electron beam is re-circulated in the storage ring and, while the microbunching becomes "thermalized" from turn to turn, the evolution of other bunch
Flexible Energy LUND ENERGY WORKSHOP 2016 October 20th 2016, 9.00 – 16.15 Venue: Palaestra, Lundagård, Lund Welcome to an Energy Workshop in Lund on the theme ”Flexible energy” With the new climate agreement in Paris the transition towards an emissions free power system is clear and globally accepted. This transition has been ongoing for a while in Sweden, but with the new target for climate neutr

We focus our research on polymers for energy and sustainability. The activities span across macromolecular design, synthesis and characterization, polymer self-assembly, and material structure and properties. We are especially motivated by the global challenges concerning energy and sustainability that drive the research for new multifunctional and high-performing polymer materials. This requires

Among concentrating solar power technologies, direct steam generation solar tower power plants represent a promising option. These systems eliminate the usage of heat transfer fluids allowing for the power block to be run at greater operating temperatures and therefore further increasing the thermal efficiency of the power cycle. On the other hand, the current state of the art of these systems doe
Bananas are widely consumed fruits with over 140 metric tons produced annually. As much as 336 metric tons of banana pseudo-stems, sheaths, piths, peels and leaves are produced annually. These wastes are usually discarded via composting, aerobic decomposition, incinerated or simply allowed to rot in the fields. However, these treatments may cause serious environmental and ecological problems. Mea
