An Epithermal neutron source based on an electrostatic tandem accelerator of a new type - Vacuum Insulation Tandem Accelerator, and a lithium neutron generating target has been proposed and developed at the Budker Institute of Nuclear Physics  for the Boron Neutron Capture Therapy  - the promising method for treatment of tumours and for other applications. This paper proposes and implements a flexible and customizable method for the operational data processing, allowing an operator and physicists to obtain and analyze the information during the experiment without the need of post-processing data. The application of it accelerates the process of obtaining informative data during the experimental research and automates the analysis process. Also it was proposed and implemented a process of automatic distributed journaling of the results of the experiment. As a result of the implementation of the proposed tools the productivity of the analysis of experimental data and the detailing of the experimental journal was increased the developed and implemented system of real-time data processing has shown its effectiveness and has become an integral part of the control system, data collection and data storage of the epithermal neutron source.
