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

Initiating the gain process in a free-electron laser (FEL) from an external highly coherent source of radiation is a promising way to improve the pulse properties such as temporal coherence and synchronization performance in time-resolved pump-probe experiments at FEL facilities, but this so-called "seeding" suffers from the lack of adequate sources at short wavelengths. We report on the first suc

The existing thermionic RF-gun (tungsten-BaO cathode) at the MAX-lab linac injector has been adapted for photo cathode operation. Important parameters of this system for free electron laser experiments, like emittance and charge, were measured giving 5.5 mmmrad at 70 pC (see below). A more detailed report on that setup, including laser and electron optics is given.

Vår blick på världen är inte neutral, utan medskapande. När vi betraktar ett fotografi i ett vardagligt sammanhang registrerar vår blick inte bara sinnesdata, utan skapar också mening utifrån det vi tror oss veta om ­världen. Insikten om att blicken inte är neutral får politiska implikationer då det innebär att det betraktades mening inte är given. I maktspelet om blicken blir frågan om vems blick

The growth of oxides and thin films is important in a wide range of applications, including coating technology, production of solar cell materials, and formation of dielectric layers in the semiconductor industry. These growth processes necessitate the interaction of a solid surface with a gas/vapor or liquid phase. The chemical processes that take place during the interaction of the solid with th

The concept of sharing is commonly employed in brand narratives of platform-based start-ups to recruit users. This paper examines sharing as a brand ideology and how it is enacted by companies in the startup phase of business. As the sharing start-ups’ business model is dependent on transaction fees generated on the platforms, traction (i.e. a high volume of users) is critical for success. By anal

We present midrapidity measurements from the PHENIX experiment of large parity-violating single-spin asymmetries of high transverse momentum electrons and positrons from W±/Z decays, produced in longitudinally polarized p+p collisions at center of mass energies of s=500 and 510 GeV. These asymmetries allow direct access to the antiquark polarized parton distribution functions due to the parity-vio

The article examines how European narratives of crisis have been related to religion in different eras by different factions and with varying intentions. In the first section, I offer some examples from the interwar era, in which religion was used as part both of a conservative nationalistic narrative of crisis and a progressive liberal one. Secondly, I revisit some of the post-war debates, in whi

This article was originally given as a key note at the conference Critique, Protest and Reform (Oslo, 2017), aimed at exploring the rich and complex philosophical, political and religious traditions that the Reformation gave rise to. Within this framework, I consider a philosophical example of this complexity. More specifically, I describe how the anti-Jewish strand of Protestant theology became p
