Demonstration of surface electron rejection with interleaved germanium detectors for dark matter searches

The following article appeared in Applied Physics Letters 103.16 (2013): 164105 and may be found at http://scitation.aip.org/content/aip/journal/apl/100/26/10.1063/1.4729825The SuperCDMS experiment in the Soudan Underground Laboratory searches for dark matter with a 9-kg array of cryogenic germanium detectors. Symmetric sensors on opposite sides measure both charge and phonons from each particle interaction, providing excellent discrimination between electron and nuclear recoils, and between surface and interior events. Surface event rejection capabilities were tested with two 210 Pb sources producing ∼130 beta decays/hr. In ∼800 live hours, no events leaked into the 8–115 keV signal region, giving upper limit leakage fraction 1.7 × 10−5 at 90% C.L., corresponding to < 0.6 surface event background in the future 200-kg SuperCDMS SNOLAB experiment.This work is supported in part by the National Science Foundation (Grant Nos.

Special aspects and implementation of the system approach into trainer's professional activity

Purpose: to determine the special aspects and implementation of the system approach into trainer's professional activity. Material & Methods: the content of the systemic approach was considered. The following research methods were used: theoretical analysis and generalization of scientific and methodological information, structural and functional analysis, system analysis. Results: defines the principles, the content of the system approach and the algorithm of its realization in practice of trainer. Conclusion: the basis for the use of the system approach in practice is the expected sport outcome; a systematic approach in the work process should be implemented through coordination, subordination, hierarchical links, development links, backward and direct links

Rare Nonleptonic Decays of the Omega Hyperon: Measurements of the Branching Ratios for Omega-+ --> Xi*0(1530) (anti-Xi*0(1530)) pi-+ and Omega-+ --> Xi-+ pi+- pi-+

A clean signal of 78 (24) events has been observed in the rare nonleptonic particle (antiparticle) decay modes {Omega}{sup {-+}} {yields} {Xi}{sup {-+}}{pi}{sup {+-}}{pi}{sup {-+}} using data collected with the HyperCP spectrometer during Fermilab's 1999 fixed-target run. We obtain B({Omega}{sup -} {yields} {Xi}{sup -}{pi}{sup +}{pi}{sup -}) = [4.32 {+-} 0.56(stat) {+-} 0.28(syst)] x 10{sup -4} and B({Omega}{sup +} {yields} {Xi}{sup +}{pi}{sup -}{pi}{sup +}) = 3.13 {+-} 0.71(stat) {+-} 0.20(syst) x 10{sup -4}. This is the first observation of the antiparticle mode. Our measurement for the particle mode agrees with the previous experimental result and has an order-of-magnitude better precision. We extract the contribution from the resonance decay mode {Omega}{sup {-+}} {yields} {Xi}*{sub 1530}{sup 0} ({ovr {Xi}*{sub 1530}{sup 0}}){pi}{sup {-+}} to the final state {Xi}{sup {-+}}{pi}{sup {+-}}{pi}{sup {-+}}. This the first actual measurement of the resonance-mode branching ratios, gives B({Omega}{sup -} {yields} {Xi}*{sub 1530}{sup 0} {pi}{sup -}) = [4.55 {+-} 2.33(stat) {+-} 0.38(syst)] x 10{sup -5}, B({Omega}{sup +} {yields} {ovr {Xi}*{sub 1530}{sup 0}}{pi}{sup +}) = [1.40 {+-} 2.83(stat) {+-} 0.12(syst)] x 10{sup -5} and disagrees with the current Particle Data Group review value, being {approx} 14 times smaller. Since the central value of the resonance-mode branching ratio is less than two standard deviations away from zero, we also calculate branching ratio upper limits at 90% confidence level: B({Omega}{sup -} {yields} {Xi}*{sub 1530}{sup 0} {pi}{sup -}) &lt; 7.61 x 10{sup -5} and B({Omega}{sup +} {yields} {ovr {Xi}*{sub 1530}{sup 0}} {pi}{sup +}) &lt; 5.61 x 10{sup -5}. This analysis provides new data on nonleptonic hyperon decays which allows studies of how weak interaction processes occur in the presence of strong interactions

Influence of the experimental program of trainings in armsport on the power indexes of basic muscle groups of 16-17-years-old armwrestlers.

<p>The features of influence of the experimental program of trainings are considered in armsport. The program is developed taking into account age-dependent changes in the organism of young sportsmen, features of development of force and power endurance, structure of long-term preparation. The program is directed on development of force and static power endurance of basic muscle groups of sportsmen. In researches took part 30 sportsmen aged 16-17 years old. It is set that the stage of the specialized base training is foreseen by the increase of time on perfection of technique of fight at the table to 15 %. The special attention must be spared the special physical youth development. The block of the specialized training to send to development of explosive force, workings of weak corners, change of character of work is recommended. It is set that trainings with the static loadings are obligatory and in the general volume of loadings must make no less than 20 %. It is necessarily necessary to plan the block of the restoration training for physical and psychological renewal of sportsmen after the conducted setup time and appearance on competitions, exposure and comprehension of sufferet errors and search of methods of their removal.</p

Ambient Dose and Dose Rate Measurement in SNOLAB Underground Laboratory at Sudbury, Ontario, Canada

The paper describes a system and experimental procedure that use integrating passive detectors, such as thermoluminescent dosimeters (TLDs), for the measurement of ultra-low-level ambient dose equivalent rate values at the underground SNOLAB facility located in Sudbury, Ontario, Canada. Because these detectors are passive and can be exposed for relatively long periods of time, they can provide better sensitivity for measuring ultra-low activity levels. The final characterization of ultra-low-level ambient dose around water shielding for ongoing direct dark matter search experiments in Cube Hall at SNOLAB underground laboratory is given. The conclusion is that TLDs provide reliable results in the measurement of the ultra-low-level environmental radiation background
