Abstract

The first stage of the proposed polarization program SPASCHARM includes the measurements of the single-spin asymmetry (SSA) in exclusive and inclusive reactions with production of stable hadrons and the light meson and baryon resonances.In this study we foresee of using the variety of the unpolarized beams (pions, kaons, protons and antiprotons) in the energy range of 30-60 GeV. The polarized proton and deuteron targets will be used for revealing the flavor and isotopic spin dependencies of the polarization phenomena. The neutral and charged particles in the final state will be detected., Comment: 8 pages, 4 figures, talk reported in the XIII Workshop On High Energy Spin Physics DSPIN-09, Dubna, Russia September 1 - 5, 2009

10. Effect of the Composition and Synthesis Method on the Sorption Properties of NaNO3/MgO Sorbents with Respect to Carbon Dioxide.

Author

Nikulina, I. E., Derevshchikov, V. S., Pakharukova, V. P., Snytnikov, P. V., and Potemkin, D. I.

Abstract

In this work, sorbents based on magnesium oxide MgO modified with NaNO3 taken in a concentration of 5–50 mol % have been synthesized and studied by various methods. It has been shown that the optimum synthesis method is impregnation of the MgO precursor. The optimum concentration of NaNO3 as a modifier is 10 mol %; this concentration provides a sorption capacity of 6.5 mmol CO2/gsorb within 1 h of sorption at 320°C and a CO2 content of 50 vol %. The sorption capacity achieved in 10 consecutive sorption–desorption cycles for 10 mol % NaNO3 is 4.5–5.5 mmol CO2/gsorb within 30 min of sorption at 50 vol % CO2 and temperatures of 300 and 350°C for the sorption and desorption stages, respectively. It has been found that an increase in the total sorption pressure to 10 atm makes it possible to decrease the sorption temperature to 220–260°C, and the achieved sorption capacity is 4.0 mmol CO2/gsorb at 25 vol % CO2, which is almost 2 times higher than the sorption capacity value at 1 atm. It has been shown that treatment with steam and hydrogen does not lead to a significant change in the sorption properties and phase composition of MgO modified with NaNO3. [ABSTRACT FROM AUTHOR]

Abstract

Comparisons of particle production from high-energy ion collisions with next-to-leading order perturbative QCD calculations show good agreement down to moderate transverse momentum values. Distributions of azimuthal angle differences between coincident hadrons in these collisions support a partonic origin to the particle production again down to moderate transverse momentum values. The rapidity dependence of inclusive and coincident particle production can therefore be used to probe parton distribution functions down to small momentum fractions where theory anticipates that parton saturation could be present. This paper describes how such experiments could be completed. © Springer-Verlag 2005.

Abstract

The sorption-catalytic steam conversion of CO using a mechanical mixture of 5 wt.% Pt/Ce0.75Zr0.25O2 catalyst grains and 10 mol.% NaNO3/MgO sorbent was studied. It was shown under the model conditions that initially MgO adsorbs СО2 only slightly, whereas its promotion with NaNO3 leads to a considerable growth of the adsorption dynamic capacity in the temperature range of 300–350 °С with a maximum at 320 °С. High activity and selectivity of the catalyst in steam conversion of CO were demonstrated for a model mixture with the composition (vol.%) 11.6 CO, 61 H2 and 27.4 H2O: the concentration of СО at the reactor outlet did not exceed 1 vol.% in the temperature range of 220– 400 °С (the minimum value of 0.3 vol.% was observed at 240 °С), and СН4 – at temperatures below 320 °С (0.61 vol.% at this point). The use of the sorbent in a mixture with the catalyst in the sorption-catalytic steam conversion of CO at 320 °С led to a considerable decrease in its sorption capacity; this may be related to the conversion of all NaNO3 into Na2CO3, which decomposed incompletely during regeneration. Nevertheless, this made it possible to decrease twofold the outlet concentrations of СО and СН4 as compared to the values observed at the indicated temperature in the experiment without a sorbent: particularly, in the middle of the first adsorption cycle they were equal to 6.1·10–4 and 8.2·10–2 vol.%, respectively, on a dry gas basis. Thus, the indicated approach to the sorption-catalytic conversion of CO was shown to be promising; further studies are needed to increase the capacity and stability of the presented type of sorbents.

Abstract

Physicochemical properties of commercial medical CO2 sorbents Amsorb Plus, Draeger 800, Draeger free, Loflosorb, Sodasorb, Sofnolime, Spherasorb, Ventisorb, as well as of the Russian adsorbent HPI were studied to determine the chemical compositions, textural characteristics, effective protection time with respect to CO2; crushing and attrition resistance of granular sorbents were measured using the SHELL SMS-1471 and ASTM D 4058 96 procedures. The best performance (a high CO2 capacitance, strength) was observed with Draeger 800. The obtained data on operating properties of commercial sorbents and recommendations can be useful for medicine, rescue works, as well as for scientific and production activities when cleaning air mixtures from carbon dioxide is necessary.

20. Sorption-Enhanced Water Gas Shift Reaction over a Mechanical Mixture of the Catalyst Pt/Ce0.75Zr0.25O2 and the Sorbent NaNO3/MgO.

Author

Abstract

Results of studying the sorption-enhanced water gas shift reaction over a mechanical mixture of grains of 5 wt % Pt/Ce0.75Zr0.25O2 catalyst and 10 wt % NaNO3/MgO sorbent are presented. It is shown that pure magnesium oxide sorbs virtually no СО2 under model conditions, while its promotion with NaNO3 substantially improves the dynamic sorption capacity in the 300–350°C range of temperatures with a maximum at 320°C. The catalyst shows high activity and selectivity in the water gas shift reaction for a model mixture (CO, 11.6; H2, 61; H2O, 27.4 vol %). The concentration of CO at the outlet from the reactor is less than 1 vol % in the 220–400°C range of temperatures (the minimum is 0.3 vol % at 240°C) with СН4 at the temperatures below 320°C (0.61 vol % at this point). Using this sorbent in mixtures with a catalyst in the sorption-enhanced water gas shift reaction at 320°C substantially reduces its sorption capacity, due probably to the full conversion of NaNO3 into Na2CO3 that is not completely decomposed at the stage of regeneration. This nevertheless allows the outlet СО and СН4 concentrations to be halved, relative to values observed at this temperature in experiments with no sorbent: 6.1 × 10−4 and 8.2 × 10−2 vol % per dry gas basis at the middle of the first adsorption cycle. Prospects for using this approach in the sorption-enhanced water gas shift reaction and the need for further studies on improving the capacity and stability of the presented sorbents are described.

Abstract

A measurement of the single-spin asymmetry A(N) in P up + P --> pi-0 + X at 200 GeV with x(F) = O shows a transition in the production process from a "low-x(T)" regime with A(N) = 0, through an intermediate region of negative asymmetry, to a "high-x(T)" regime with A(N) > 0.3. This transition occurs at x(T) almost-equal-to 0.4 and is consistent with x(T)-scaling of A(N) in pion production using polarized beams or targets from square-root -s = 5.2 to 19.4 GeV. Results for A(N) in eta-production by polarized protons and in pi-0 production by polarized antiprotons are also presented.

Abstract

We present first measurements of the pseudorapidity and azimuth $(\eta,\phi)$ bin-size dependence of event-wise mean transverse momentum $$ fluctuations for Au-Au collisions at $\sqrt{s_{NN}} = 200$ GeV. We invert that dependence to obtain $p_t$ autocorrelations on differences $(\eta_\Delta,\phi_\Delta)$ interpreted to represent velocity/temperature distributions on ($\eta,\phi$). The general form of the autocorrelations suggests that the basic correlation mechanism is parton fragmentation. The autocorrelations vary strongly with collision centrality, which suggests that fragmentation is strongly modified by a dissipative medium in the more central Au-Au collisions relative to peripheral or p-p collisions. \\, Comment: 7 pages, 3 figures

Abstract

We report the first inclusive photon measurements about mid-rapidity (|y| photon photon decay channel. The fractional contribution of the pi0 -> photon photon decay to the inclusive photon spectrum decreases by 20% +/- 5% between pt = 1.65 GeV/c and pt = 2.4 GeV/c in the most central events, indicating that relative to pi0 -> photon photon decay the contribution of other photon sources is substantially increasing., 13 pages, 14 figures, submitted to Phys.

Abstract

The FELIX Collaboration proposes the construction of a full acceptance detector for the LHC, to be located at Intersection Region 4, and to be commissioned concurrently with the LHC. The primary mission of FELIX is the study of QCD: to provide comprehensive and definitive observations of a very broad range of strong-interaction processes. This document contains a description of the detector concept including details of the individual detector elements and their performance characteristics, an extensive discussion of the physics menu, and the plans for integration of FELIX into the collider lattice and physical environment.

Abstract

Comparisons of particle production from high-energy ion collisions with next-to-leading order perturbative QCD calculations show good agreement down to moderate transverse momentum values. Distributions of azimuthal angle differences between coincident hadrons in these collisions support a partonic origin to the particle production again down to moderate transverse momentum values. The rapidity dependence of inclusive and coincident particle production can therefore be used to probe parton distribution functions down to small momentum fractions where theory anticipates that parton saturation could be present. This paper describes how such experiments could be completed. © Springer-Verlag 2005.

Abstract

A new experiment SPASCHARM devoted to a systematic study of polarization phenomena in hadron-hadron interactions in the energy range 10-70 GeV is under preparation at IHEP (Protvino). The physical observables will be single-spin asymmetries, hyperon polarizations and spin-density matrix elements. A universal setup will detect and identify various neutral and charge particles in the full azimuthal angle and a wide polar angle range. A polarized target is used to measure the SSA. The SPASCHARM sub-detectors are being designed and constructed now. The possibility of obtaining a polarized proton beam for the SPASCHARM experiment from Lambda decays is under study.

Abstract

The two-spin parameter A(LL) in inclusive pi-0 production by longitudinally-polarized protons and antiprotons on a longitudinally-polarized proton target has been measured at the 200 GeV Fermilab spin physics facility, for pi-0,s at X(F) = 0 with 1 less-than-or-equal-to p(t) less-than-or-equal-to 3 GeV/c. The results exclude, at the 95% confidence level, values of A(LL) (pp) > 0.1 and < -0.1, for pi-0,s produced by protons, and values of A(LL) (antiproton-antiproton) > 0.1 and < -0.2 for incident antiprotons. The relevance of A(LL) (pp) for the gluon spin density is discussed. The data are in good agreement with "conventional", small or zero, gluon polarization.

Abstract

The results obtained by measuring, at the U-70 accelerator in Protvino, the single-spin asymmetry A in the reaction p + p → π + X at a beam energy of 50 GeV in the Feynman variable range of −0.6 < x < −0.1 are presented. The asymmetry A is close to zero at small | x| and grows in magnitude with | x|, reaching 6.4% in the region of | x| > 0.25. The results of these measurements agree with data of the E704 experiment on the asymmetry of π mesons at the Fermi National Accelerator Laboratory in the region of polarized-beam fragmentation and with the results of measurements in the region of polarized-target fragmentation that were performed in Protvino by using a 40-GeV π-meson beam and a 70-GeV proton beam.
