Abstract Antihydrogen atoms with K or sub-K temperature are a powerful tool to precisely probe the validity of fundamental physics laws and design highly sensitive experiments needs antihydrogen controllable well defined conditions. We present here experimental results on production in pulsed mode which time when 90% produced is known an uncertainty ~250 ns. The source generated by charge-exchange reaction between Rydberg positronium atoms—produced via injection positron beam into...
Positronium in the $2^{\phantom{\rule{0.16em}{0ex}}3}\mathrm{S}$ metastable state exhibits a low electrical polarizability and long lifetime (1140 ns), making it promising candidate for interferometry experiments with neutral matter-antimatter system. In present work, positronium is produced, absence of an electric field, via spontaneous radiative decay from $3^{\phantom{\rule{0.16em}{0ex}}3}\mathrm{P}$ level populated 205-nm UV laser pulse. Thanks to short temporal length pulse, 1.5 ns full...

The cloud excitation obtained with a UV laser pulse experimental vacuum chamber presence guiding magnetic field 25 mT and average electric 300 V/cm. indication production from novel analysis technique single-shot...
Abstract We describe a multi-step “rotating wall” compression of mixed cold antiproton–electron non-neutral plasma in 4.46 T Penning–Malmberg trap developed the context AEḡIS experiment at CERN. Such traps are routinely used for preparation antiprotons suitable antihydrogen production. A tenfold antiproton radius has been achieved, with minimum only 0.17 mm. experimental conditions necessary to perform such compression: minimizing tails electron density distribution is paramount ensure that...
We characterized the pulsed Rydberg-positronium production inside Antimatter Experiment: Gravity, Interferometry, Spectroscopy ($\mathrm{AE}\overline{\text{g}}\mathrm{IS}$) apparatus in view of antihydrogen formation by means a charge exchange reaction between cold antiprotons and slow atoms. Velocity measurements on positronium along two axes cryogenic environment ($\ensuremath{\approx}10\phantom{\rule{0.16em}{0ex}}\mathrm{K}$) $1\phantom{\rule{0.16em}{0ex}}\mathrm{T}$ magnetic field were...
Modern realities regarding educational policy in the regions dictate need to be guided by many nuances Russia. The importance of education for non-Russians was also perceived as one most important components Russian Empire periphery, main function which nationalization peoples outskirts. Taking into account fact that pre-revolutionary Russia "national school" considered a national school, it is obvious presence schools other nations, not mother language, could take place. Based on this,...
The efficient production of cold antihydrogen atoms in particle traps at CERN's Antiproton Decelerator has opened up the possibility performing direct measurements Earth's gravitational acceleration on purely antimatter bodies. goal AEgIS collaboration is to measure value
