Bunch Length Measurements with Passive Harmonic Cavities for Non-Uniform Fill Patterns in a 100 MHz RF

The MAX IV facility includes two storage rings operated at 1.5 GeV and 3 GeV, which are both designed to operate with a uniform, multibunch fill pattern. Both rings have a 100 MHz RF system and employ passive harmonic cavities to damp instabilities and increase Touschek lifetime. Recently, a discussion on timing modes at the MAX IV storage rings has been initiated by the user community. Creating o

Bäckaskog - a Norbertine Abbey in the Circary of Denmark and Norway

In the twelfth century the Norbertine order was introduced in parts of Scandinavia. One initiator in the north was Eskil, the powerful archbishop of Lund. However, in the beginning of the thirteenth century the mendicant orders were introduced by successors to the archbishopric. This led to a general decline of other orders. In spite of that the Norbertines managed to prosper in Bäckaskog, an abbeIn the twelfth century the Norbertine order was introduced in parts of Scandinavia.

Sn-seeded GaAs nanowires grown by MOVPE

It has previously been reported that in situ formed Sn nanoparticles can successfully initiate GaAs nanowire growth with a self-assembled radial p–n junction composed of a Sn-doped n-type core and a C-doped p-type shell. In this paper, we investigate the effect of fundamental growth parameters on the morphology and crystal structure of Sn-seeded GaAs nanowires. We show that growth can be achieved

Lika ideal, skilda uttryck : cistercienserna och premonstratenserna i östra Danmark

Under 1100-talet kom cistercienserna och premonstratenserna att utgöra bland de mest spridda och inflytelserika religiösa ordnarna . Även om cistercienserna var en monastisk orden och premonstratenserna en klerikal orden var båda ett resultat av reformrörelser som strävade efter striktare ideal enligt deras respektive regler. För att möjliggöra detta hade de förlagt sina moderkloster i isolerade o

Residual stress analysis of machined lead-free and lead-containing brasses

Legislations demand low lead content in drinking water and low lead leaching from the water supply facilities. Lead-free brass (LFB) can fit in. The benefits of such alloy are acknowledged in both functional and environmental points of view. The relatively high strength of LFB means that the process condition and residual stress generation can be different as compared to the conventional brass. In
