We present a description of the GBAR positron (e+) trapping apparatus, which consists three stage Buffer Gas Trap (BGT) followed by High Field Penning (HFT), and discuss its performance. The overall goal experiment is to measure acceleration neutral antihydrogen (H¯) atom in terrestrial gravitational field neutralising positive ion (H¯+), has been cooled low temperature, observing subsequent H¯ annihilation following free fall. To produce one H¯+ ion, about 1010 positrons, efficiently...
The GBAR experiment aims to measure the gravitational acceleration of antihydrogen H.It will use H+ ions formed by interaction antiprotons with a dense positronium cloud, which require about 10 positrons produce one H + .We present first results on positron accumulation, reaching 3.8 ± 0.4 × 8 e collected in 560 s.

ATLAS Data Acquisition/Event Filter "-1" (DAQ/EF1) project provides the opportunity to explore use of commodity hardware (PCs) and Open Source Software (Linux) in DAQ applications. In DAQ/EF-1 there is an element called LDAQ which responsible for providing local run-control, error-handling reporting a number read-out modules front end crates. This also event data monitoring interface with global control system (Back-End). We present results evaluation Linux operating made context where are...
