A new yet little understood threat to our ecosystems is microplastics.
The almost identical charge-to-mass ratios of fully ionized helium-4 and carbon-12 ions enable simultaneous acceleration in hadron therapy synchrotrons. At the same energy per mass, helium exhibit a stopping range approximately three times greater than carbon ions. They can therefore be exploited for online verification downstream patient during ion beam irradiation. One possibility creating this mixed is accelerating two species sequentially through LINAC subsequently "mixing" them at...
We report on the fabrication of organic electrochemical transistors structured by nanoimprint lithography. The devices were scaled down as a result our previous findings for inkjet printed transistors, where reduced source-drain width and shorter distance to gate resulted in higher ON-to-OFF current ratios. could show that these also prove true with feature sizes below 10 μm. Furthermore, we fabricated inverters NAND gates switching times 1 s. These logic mark an important step toward their...
A zero-field cooled superconducting shield was previously proposed to realize a high-field (at least 3 T) septum magnet for the Future Circular Collider proton-proton ring. In this paper, we present conceptual design of complete prototype including with an optimized shape and simple cost-effective using canted cosine theta concept. 2D optimization coil geometry realistic simulation fieldmap field homogeneity are presented taking into account nonlinear penetration magnetic shield.
The sPHENIX Time Projection Chamber Outer Tracker (TPOT) is a Micromegas based detector. It part of the experiment that aims to facilitate calibration Chamber, in particular correction time-averaged and beam-induced distortions electron drift. This paper describes detector mission, setup, construction, installation, commissioning performance during first year data taking.
One challenge on the path to delivering FLASH-compatible beams with a synchrotron is facilitating an accurate dose control for required ultra-high rates. We propose use of pulsed RFKO extraction instead continuous beam delivery as way delivered per Voxel. In first feasibility test, rates in pulses up 600 Gy s
One option for a future circular collider at CERN is to build 13.5 TeV hadron synchrotron, or High Energy LHC (HE-LHC) in the tunnel. Injection and dump systems will have be upgraded cope with higher beam rigidity increased damage potential of beam. The required modifications transfer hardware are highlighted view technology advancements field kicker switch technology. An optimised straight section optics shown.
The LHC Beam Dump System is one of the most critical systems for reliable and safe operation LHC. A dedicated dilution system required to sweep beam over front face graphite dump core in order reduce deposited energy density. High Luminosity Large Hadron Collider (HL-LHC) project foresees increase total intensity ring by nearly a factor two, resulting correspondingly higher deposition core. In this paper, pattern case normal as well relevant failure cases are presented. implications possible...
During Long Shutdown 2 (LS2) at CERN, the new Linac4 (L4) accelerator was connected to PS Booster (PSB) inject 160 MeV H − beam into 4 superposed PSB rings. In order achieve this, a completely charge-exchange injection chicane system, with 200 µg/cm carbon stripping foil units, convert negative hydrogen ions protons, by off electrons, has been installed. Beam commissioning of this system started in December 2020 and different types foils have used for purpose. parallel, efficiency...
One challenge on the path to delivering FLASH-compatible beams with a synchrotron is facilitating an accurate dose-control for required ultra-high dose rates. We propose use of pulsed RFKO extraction instead continuous beam delivery as way control delivered per Voxel. In first feasibility test rates in pulses up 600 Gy/s were observed, while granularity at which was expected be well below 0.5 Gy.
The mainstream planar technology is marked by physical and technological limitations, which have a severe impact on the system characteristics. performance, multifunctionality reliability of microelectronic systems will be mainly limited wiring between IC's subsystems. "onchip" also leads to critical performance bottleneck for future IC generations can solved only temporarily introduction additional metallization layers innovative materials (copper, low-/spl epsiv/-dielectrics). 3D...
