Evidence for a flavor asymmetry between the $\overline{u}$ and $\overline{d}$ quark distributions in proton has been found deep-inelastic scattering Drell-Yan experiments. The pronounced dependence of this on $x$ (fraction nucleon momentum carried by partons) observed Fermilab E866 experiment suggested drop $\overline{d}(x)/\overline{u}(x)$ ratio $x>0.15$ region. We report results from SeaQuest E906 with improved statistical precision large region up to $x=0.45$ using 120 GeV beam. Two...
The main aim of the study is to perform long-term stability test gain single mask triple GEM detector. A simple method used for this using a radioactive X-ray source with high activity. continued till accumulation charge per unit area > 12.0 mC/mm2. details chamber fabrication, set-up, measurement and results are presented in paper.
The SeaQuest spectrometer at Fermilab was designed to detect oppositely-charged pairs of muons (dimuons) produced by interactions between a 120 GeV proton beam and liquid hydrogen, deuterium solid nuclear targets. primary physics program uses the Drell-Yan process probe antiquark distributions in target nucleon. consists system, two dipole magnets four detector stations. upstream magnet is closed-aperture iron which also serves as dump, while second an open aperture magnet. Each stations...
To enable a dense integration of model synapses in spiking neural networks (SNN) hardware, various nanoscale devices are being considered. Such devices, besides exhibiting spike-timing dependent plasticity (STDP), need to be highly scalable, have large endurance and require low energy for transitioning between states. In this work, first, we introduce empirically determine two new specifications resistive random-access memory (RRAM) based synapse: number conductance levels per synapse...
Spiking Neural Networks (SNN) are more closely related to brain-like computation and inspire hardware implementation. This is enabled by small networks that give high performance on standard classification problems. In literature, typical SNNs deep complex in terms of network structure, weight update rules learning algorithms. makes it difficult translate them into hardware. this paper, we first develop a simple 2-layered software which compares with the state art four different data-sets...
Study of the stability gain and energy resolution for a triple GEM detector has been performed under continuous radiation X-ray with high rate, using premixed gas Argon CO$_2$ in 70/30 ratio conventional NIM electronics. A strong Fe$^{55}$ source is used this study. The novelty study that test same to irradiate chamber monitor spectrum. not collimated point but exposed larger area. Effect temperature pressure on these parameters are also studied. detail method measurement first results...
Abstract The long-term stability in terms of gain and energy resolution a prototype triple Gas Electron Multiplier (GEM) detector has been investigated with high rate X-ray irradiation. Premixed Ar/CO 2 (80:20) (90:10) gases have used for this study. A strong Fe 55 source is to irradiate the chamber. uniqueness work that same GEM also monitor spectra. This arrangement important since it reduces mechanical complexity using an generator as well cost setup. small area chamber exposed...
Basic R & D have been carried out with one small straw tube detector prototype premixed gas of Ar+CO2 in 70:30 and 90:10 ratio. The gain the energy resolution are measured Fe55 X-ray source. Effect temperature pressure on these parameters measured. variation rate per unit length also details test set-up, method measurement results presented this paper.

Such device, besides exhibiting spike-time dependent plasticity (STDP), needs to be highly scalable, have large endurance and require low energy for transitioning between states. In this work, we first introduce empirically determine two new specifications an synapse SNNs: number conductance levels per maximum learning-rate. the best our knowledge, there no...
