DIGITAL PROCESSING OF PHOTOS FROM a 4π TRACK DETECTOR

Abstract

A measuring complex with a digital data bank of stereo photos of photonuclear reactions on 4He, 12C, 14N, and 16O nuclei got from a 4 track detector has been created. The file name was formatted into a certain type of record, which included information about the experiment and the position in the data bank. A graphical application was presented that allowed semi-automatic determination of points along tracks of different lengths and curvatures. Methods and algorithms allowing to transfer into the camera system and perform event reconstruction were developed. Additional programs for the physical analysis of the reconstructed events and the graphical representation of the obtained results were created.

INVESTIGATION OF THE PARTIAL CHANNEL OF 8Be NUCLEUS GROUND STATE FORMATION IN THE 14N(γ,2α6Li) REACTION

“…In Fig. 2,a, the histogram shows the dependence of the number of events on the -quantum energy in the 14 N(, 6 Li) 8 Ве 0 reaction with a step of 0.5 MeV in E γ .…”

“…In this article, we present results obtained by studying the photodisintegration of nitrogen nuclei via the reaction 14 N(,2 6 Li), which will provide new information on the evolution of a complex cluster structure beyond α-clustering.…”

“…This report is a continuation of work [5], which published the results of the study of this reaction. Earlier it was reported [6] about the creation of a digital bank of stereo photographs obtained by photographing the working area of a 4π detector (diffusion camera in a magnetic field). The diffusion chamber [17] was placed in a magnetic field and was exposed to bremsstrahlung photons at an endpoint energy 150 MeV.…”

DIGITAL STUDY OF THE 14N(γ,2α)6Li REACTION

“…COORDINATES ALONG TRACKS In the experiment, during the sessions of irradiation of the camera, the working area of the camera was photographed by two 2-lens cameras. A large amount of information on multiparticle photoreactions was collected and an experimental complex with a digital data bank of stereo frames and a set of graphic programs that allow to restore events and perform physical analysis of the obtained data was created [11]. Photo frames have a structured name with the maximum necessary information about the experiment session.…”

“…In [11], a method of digital semi-automatic measurement of the coordinates of points along the track was proposed. This allowed us to compare the digital method and the method using special devices.…”
