The Jews of the Russian Empire in the system of education modernization: forms of incorporation and preservation of national and religious identity (on the example of Dagestan)

The education sector is one of the priority areas in the Russian modernization at the present stage of development. In the conditions of multinational Russia, the question of its national component becomes especially urgent. Taking into account the understanding of the development of an acceptable state policy and the impossibility of neglecting the historical experience of previous eras, in particular the experience of the Russian Empire, the article attempts to consider issues related to the functioning of national schools in the context of the policy of Russification of the periphery using the example of one of the ethnic groups - the Jewish population. The article is devoted to the analysis of the creation of a system of national schools through the introduction of the Russian language in the conditions of the functioning of an extensive network of educational institutions of a religious type in the conditions of overdue modernization in the empire. Dagestan has been chosen as a geographic area for the research as a region where the Mountain Jews historically lived. The chronological framework of the study focuses on the period of the turn of the XIX - early XX centuries, which is explained by attempts to monopolize the Russian educational system and the introduction of restrictive measures in relation to the ethno-confessional school. Such a study, as an experience of the state policy of the Russian Empire on the organization of education for various ethnic groups, makes it possible to identify the positive and negative aspects in the process under consideration, which will allow to avoid the repetition of similar mistakes in the new Russia in the future. Official documentary materials stored in the funds of the central and local archives of the Russian Federation, memoirs, materials from periodicals have been used in the research

Orthodox Religious Organizations in the Context of Transformation of State-Confessional Relations (1985-1997): Problems And Features (the Case of the Dagestan Republic)

The increased importance of the religious factor, which influences various aspects of social life, has made it relevant for current academic research. The interrelation of this factor with the political history of Russia makes it one of the most complex and priority areas in the confessional policy of the State, and provokes the rethinking of Russia’s policy in the national regions. The issues related to the relationship between official authorities and Orthodox organizations in polyconfessional regions with a predominance of Muslim populations, particularly in Dagestan are of particular interest for us. The absence of historical interpretations on the history of Orthodox organizations in the transitional and post-Soviet periods makes the stated subject topical for identifying and introducing into scientific circulation a specific material that regional studies can provide. Proceeding from the above, in the proposed paper for the first time in regional historiography we’ve made an attempt to consider the transformation processes in the socio-political situation in the country during the transitional and first decade of the post-Soviet period (1985-1997) and their influence on the development of the Orthodox religion, Christian believers and clergy in Dagestan. We’ve made conclusion about the latent process of religious orthodox revival in the republic against the background of the general spiritual crisis in the country during the transitional period of history, conditioned by the continuing policy of “state atheism”. Atheistic worldview of governing bodies often influenced the process of building relationships with religious organizations and was characterized as “ambiguous”. Religious renaissance in the first half of the 1990s in Dagestan had its own local features, due to the deterioration of the socio-political background of the republic and was accompanied by factors that adversely affect the position of Orthodoxy here.

Pulsed production of antihydrogen

Antihydrogen atoms with K or sub-K temperature are a powerful tool to precisely probe the validity of fundamental physics laws and the design of highly sensitive experiments needs antihydrogen with controllable and well defined conditions. We present here experimental results on the production of antihydrogen in a pulsed mode in which the time when 90% of the atoms are produced is known with an uncertainty of ~250 ns. The pulsed source is generated by the charge-exchange reaction between Rydberg positronium atoms\u2014produced via the injection of a pulsed positron beam into a nanochanneled Si target, and excited by laser pulses\u2014and antiprotons, trapped, cooled and manipulated in electromagnetic traps. The pulsed production enables the control of the antihydrogen temperature, the tunability of the Rydberg states, their de-excitation by pulsed lasers and the manipulation through electric field gradients. The production of pulsed antihydrogen is a major landmark in the AEgIS experiment to perform direct measurements of the validity of the Weak Equivalence Principle for antimatter

Imaging a positronium cloud in a 1 Tesla

We report on recent developments in positronium work in the frame of antihydrogen production through charge exchange in the AEgIS collaboration [1]. In particular, we present a new technique based on spatially imaging a cloud of positronium by collecting the positrons emitted by photoionization. This background free diagnostic proves to be highly efficient and opens up new opportunities for spectroscopy on antimatter, control and laser manipulation of positronium clouds as well as Doppler velocimetry

The AEgIS experiment: Towards antimatter gravity measurements

${\rm{AE}}\bar{{\rm{g}}}{\rm{IS}}$ (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) is a CERN based experiment aiming to probe the Weak Equivalence Principle of General Relativity with antimatter by studying free fall of antihydrogen in the Earth's gravitational field. A pulsed cold beam of antihydrogen produced by charge exchange between Rydberg positronium and cold antiprotons will be horizontally accelerated by an electric field gradient. The free fall of antihydrogen will then be measured by a classical moire deflectometer. An overview of the experimental setup, present status of the experiment along with current achievements and results is presented

Compression of a mixed antiproton and electron non-neutral plasma to high densities

We describe a multi-step “rotating wall” compression of a mixed cold antiproton–electron non-neutral plasma in a 4.46 T Penning–Malmberg trap developed in the context of the AE¯gIS experiment at CERN. Such traps are routinely used for the preparation of cold antiprotons suitable for antihydrogen production. A tenfold antiproton radius compression has been achieved, with a minimum antiproton radius of only 0.17 mm. We describe the experimental conditions necessary to perform such a compression: minimizing the tails of the electron density distribution is paramount to ensure that the antiproton density distribution follows that of the electrons. Such electron density tails are remnants of rotating wall compression and in many cases can remain unnoticed. We observe that the compression dynamics for a pure electron plasma behaves the same way as that of a mixed antiproton and electron plasma. Thanks to this optimized compression method and the high single shot antiproton catching efficiency, we observe for the first time cold and dense non-neutral antiproton plasmas with particle densities n ≥ 1013 m−3 , which pave the way for an efficient pulsed antihydrogen production in AE¯gIS

Towards the first measurement of matter-antimatter gravitational interaction

The AEgIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) is a CERN based experiment with the central aim to measure directly the gravitational acceleration of antihydrogen. Antihydrogen atoms will be produced via charge exchange reactions which will consist of Rydberg-excited positronium atoms sent to cooled antiprotons within an electromagnetic trap. The resulting Rydberg antihydrogen atoms will then be horizontally accelerated by an electric field gradient (Stark effect), they will then pass through a moiré deflectometer. The vertical deflection caused by the Earth's gravitational field will test for the first time the Weak Equivalence Principle for antimatter. Detection will be undertaken via a position sensitive detector. Around 103 antihydrogen atoms are needed for the gravitational measurement to be completed. The present status, current achievements and results will be presented, with special attention toward the laser excitation of positronium (Ps) to the n=3 state and the production of Ps atoms in the transmission geometry

Gravity and antimatter: The AEgIS experiment at CERN

From the experimental point of view, very little is known about the gravitational interaction between matter and antimatter. In particular, the Weak Equivalence Principle, which is of paramount importance for the General Relativity, has not yet been directly probed with antimatter. The main goal of the AEgIS experiment at CERN is to perform a direct measurement of the gravitational force on antimatter. The idea is to measure the vertical displacement of a beam of cold antihydrogen atoms, traveling in the gravitational field of the Earth, by the means of a moiré deflectometer. An overview of the physics goals of the experiment, of its apparatus and of the first results is presented
