 Abstract: Gas detectors are based on the collection of loaded particles. Simple configuration of gas filled detector was designed with cylindrical cathode and thin anode. The cathode was made of aluminium, 8mm thick and the anode was a thin copper wire ~. The detector and electronics associated with the t. D of the UT PL test, placing an alpha source (AM 241) in the detector and filling it with R-10 gas (90% argon and 10% methane). Somar: Volsource (AM 241) inside the detector and filling the chamber with P-10 gas (90% argon and 10% methane). Voltage high and pulse height analysis of the detector with oscilloscope and MCA. The construction of the applied voltage and the rotating pulse gives us a nice play which starts at 650 V and extends up to 850 V and higher. Furthermore, from the shape of the bipolar amplified pulse we can confirm that the signal is almost free of noise and distortion due to faulty components.

Key words: electric field its interaction, research methods, origin theory, field concept.

Research objective: manifestations of electromagnetic fields, emergence theorem.

Research object: the theory of occurrence of electromagnetic oscillations. The electromagnetic interaction is the most studied of the four fundamental physical interactions because it determines most of the phenomena in the world around us. The electromagnetic interaction is responsible for the attraction of electrons to the nuclei of atoms and therefore corresponds to the formation of atoms and molecules and for their properties.

 The manifestation of electromagnetic interaction is also light - the flux of photons. The basic equations of electromagnetism are Maxwell's equation. It propagates as an electromagnetic field consisting of vector quanta. Due to the zero massif, the interaction is saccharine; An example of long range electromagnetic interaction is the reception of radiation from galaxies and quasars at a distance of billions of light years. The electromagnetic interaction involves caches and lepton having an electric charge, instead it has no effect on neutral neutrino particles [1].

In 1865 George Maxwell reorganized that electromagnetic oscillations in the inner character have the property to propagate in space with velocity [3].

 And in the mid-1960s McWell, working on experimental results (investigating the phenomenon of electromagnetic induction) came to the conclusion that in nature there is an inverse process - a variable electric field produces a variable magnetic field (vortex). Consequently, a magnetic field can be created not only by the counter of electric currents but also for an alternating electric field. Then there were experiments by Hertz which showed that electromagnetic waves have the following properties: in a homogeneous medium they propagate uniformly and enter directly; they are reflected by dielectrics and even the best conductors, while the laws of wave reflection are fulfilled; they are broken; focus; they give diffraction and interference phenomena; they are polarised. To produce electromagnetic waves, Herzz used a simple device which is now called a shear vibrator or VSrita or open-air vibrator. Herzz later called the device capable of emitting electromagnetic waves an antenna, which translates to a moustache. An important milestone in the study of electromagnetic interaction was the research and development of radio communication: when he created, in 1913, the electromagnetic oscilloscope generator with which it was possible to make reliable and high-frequency radiotelephone communication - the transmission of conversation or music using electromagnetic waves. Consequently, the existence of the electron (units of electric charge) was discovered in the 1990s. But not all materials are carriers of electric charge. Electrically neutral, such as the photon and the neutrino. This is the difference in electricity from gravity. All material materials create a gravitational field, whereas the electromagnetic field is related only to charged particles. These issues are relevant today.
