چکیده
The NEWS-G collaboration uses spherical proportional counters (SPCs) to search for weakly interacting massive particles (WIMPs). In this paper, we report the first measurements of nuclear quenching factor in neon gas at 2 bar using an SPC deployed a neutron beam TUNL facility. energy-dependence is modeled simple power law: αEnrβ; determine its parameters by simultaneously fitting data collected with detector over range energies. We measured following Ne:CH4 bar: α=0.2801±0.0050 (fit) ±0.0045 (sys) and β=0.0867±0.020 ±0.006 (sys). Our do not agree expected values from SRIM or Lindhard theory. demonstrated feasibility performing sub-keV energies gases SPCs beam.11 MoreReceived 8 September 2021Accepted 24 December 2021DOI:https://doi.org/10.1103/PhysRevD.105.052004© 2022 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasParticle dark matterTechniquesDark matter detectorsGravitation, Cosmology & Astrophysics

In this deliverable, we report on several evaluation experiments which aim to demonstrate the synergies arising from a combination of ontology design patterns and ontology learning techniques. Furthermore, we present a novel method for ontology refinement, i.e. the semi-automatic acquisition of complex domain-range restrictions, and its evaluation on the well-known SWRC ontology. A variant of t...
متن کاملNEON Crypto
NEON is a vector instruction set included in a large fraction of new ARM-based tablets and smartphones. This paper shows that NEON supports high-security cryptography at surprisingly high speeds; normally data arrives at lower speeds, giving the CPU time to handle tasks other than cryptography. In particular, this paper explains how to use a single 800MHz Cortex A8 core to compute the existing ...
متن کاملNeon Diffusion in Silver
The diffusion of Ne in Ag is investigated by bombarding Ag sheet with energetic Ne ions and observing the Ne release during constant temperature anneals; giving D=2.5 * 1.5 exp (-59.5 5 2.0 x 103 Cal/mole/ RT), for volume diffusion. The activation energy is not consistent with previous values found for other inert gases in Ag but agrees with the predictions of impurity diffusion theory for diff...
متن کاملCryptography for ARM NEON
Recent research has shown that implementations with variable execution timing may allow attackers to extract secret cryptographic keys stored on the device. Timing variances can occur due to implementation choices (e.g. data-dependent branches) or due to the internal architecture of the processor core (e.g. cache lines). In order to overcome this problem one needs to find alternative implementa...
متن کاملIntense atomic and molecular beams via neon buffer-gas cooling
We realize a continuous, intense, cold molecular and atomic beam source based on buffer-gas cooling. Hot vapor (up to 600K) from an oven is mixed with cold (15K) neon buffer gas, and then emitted into a high-flux beam. The novel use of cold neon as a buffer gas produces a forward velocity distribution and low-energy tail that is comparable to much colder helium-based sources. We expect this sou...
