Enhanced abundance of primordial HeH + Though only recently detected in space, the helium hydride ion (HeH ) is thought to be first molecule ever have formed early Universe. Novotný et al. report state-specific rate coefficients for dissociative reaction with electrons, obtained using a cryogenic storage ring combined merged electron beam (see Perspective by Bovino and Galli). They detect substantial rotational dependence decrease rates lowest states , far below values listed astrochemistry...
The High Brilliance neutron Source (HBS) is a project for next generation research facility, based on new concepts and recent technological advancements. As elementary processes it uses neither fission nor spallation, but instead low energy nuclear reactions in very compact Target-ModeratorReflector (TMR) assembly. Our facility design results efficient production of beams with high brightness. Key features HBS are: (i) competitive instrument performance, (ii) comparatively construction...
Abstract The High-Brilliance Neutron Source (HBS) project aims to design a scalable compact accelerator driven neutron source (CANS) which is competitive and cost-efficient. concept allows one optimize the whole facility including accelerator, target, moderators optics demands of individual instruments. Particle type, energy, timing, pulse structure are fully defined by requirements given instrument. In following, we present current status HBS project.
Neutrons are an essential tool in science and research for probing the structure dynamics of matter from mesoscale to picoscale seconds femtoseconds.To release neutrons ...
The neutron yield for beryllium, vanadium and tantalum irradiated with 22, 27, 33 42 MeV protons is indirectly determined by Prompt Gamma Neutron Activation Analysis (PGNAA). neutron-to-gamma conversion rate measured an AmBe calibration source. Corrections escaped neutrons are applied via MCNP simulations of the experiment using ENDF/B-VII.1 database. experimental results in good agreement obtained from deviating 0.4% to 13%.
The High-Brilliance neutron Source project (HBS) aims at developing a medium-flux acceleratordriven source based on 70 MeV, 100mA proton accelerator. concept intends to optimize the facility such that it provides high-brilliance beams for instruments operating di_erent time structures. This can be realized by three target stations irradiated with pulse sequences. appropriate pulses will distributed Multiplexer unit. In following, we present integration of this HBS beam optics as well ongoing...
The High-Brilliance Neutron Source project (HBS) aims at developing a medium-flux accelerator-driven neutron source based on 70 MeV, 100 mA proton accelerator. concept optimizes the facility such that it provides high-brilliance beams for instruments operating different time structures. This can be realized by generating an interlaced pulse structure, which is unraveled and sent to three target stations multiplexer system. In following we present developments of system JULIC accelerator...
