PRESSURIZED RF CAVITIES IN IONIZING BEAMS

Pressurized rf cavities in ionizing beams

A muon collider or Higgs factory requires significant reduction of the six dimensional emittance of the beam prior to acceleration.One method to accomplish this involves building a cooling channel using high pressure gas filled radio frequency cavities.The revlon colorstay lip liner plum performance of such a cavity when subjected to an intense par

Spin-triplet superconductivity in Weyl nodal-line semimetals

Abstract Topological semimetals are three dimensional materials with symmetry-protected massless bulk excitations.As a special case, Weyl nodal-line semimetals are realized in materials having either no inversion or broken time-reversal symmetry and feature bulk nodal lines.The 111-family, including LaNiSi, ventilationstejp LaPtSi and LaPtGe materi

Improved permeate flux and rejection of ultrafiltration membranes prepared from polyethylene terephthalate (PET) bottle waste

Abstract The vast amount of not-recycled polyethylene terephthalate (PET) bottle waste is a serious threat to the environment.In order to utilize the waste, PET ultrafiltration membranes were prepared using PET bottle waste as the raw material by using the phase inversion technique.Low molecular weight polyethylene glycol (PEG 400) was used as the

Human and birds

The paper presents the study of avifauna from the hunter-gatherer sites at the Dnieper-Dvina basin spanning time period from the 6th to 3rd millennia BC.A total of 669 trailmaster challenger 200x bird bones were identified and attributed to 46 different bird taxa, representing resident and migrant birds.They belong to four habitat groups: waterfowl
