"Development of a Monitoring System Using Modern Technologies for the IREN Facility at JINR"

I.D. Ponomarev

The IREN facility at JINR is a two-section linear electron accelerator with a neutron-producing target, which requires reliable monitoring to optimize its performance. This work presents a monitoring system for IREN that tracks key parameters such as neutron flux intensity, target and section temperatures, beam current, integral, width, and shape. The system is built using the Proxmox virtual machine management platform, along with LXC and Docker containerization technologies. Backups are stored on a NAS (Network Attached Storage). The stack includes Prometheus for metrics collection and storage, Loki for log aggregation, Grafana for visualization, Alertmanager for alerting, Nginx as a web server, Promtail for log shipping, and custom Python/Golang agents for acquiring the main metrics. Initial data analysis has already revealed meaningful correlations, helping improve the facility's operation. Current efforts are focused on integrating additional signals such as vacuum level, beam power, and others, which will enable more detailed control and further optimization of the IREN facility.

"Analysis of Energy Characteristics of the LUE-200 Accelerator Beam"

Zhironkin I.S., Mikhailov K.I., Repkin A.N., Sumbaev A.P.

The linear electron accelerator LUE-200 – the driver of the photoneutron source of the IREN JINR facility is formed by an assembly of two accelerating sections with a traveling EM wave of the 10 cm range (2856 MHz). The energy spectrum of the electron beam is one of the main parameters affecting the average power, and therefore the neutron yield. In this report, the authors attempt to systematize the results of adjusting the accelerator from the point of view of increasing the average and maximum beam energy, as well as minimizing the spectrum width. The main tools considered are the level of RF power introduced into the accelerating sections, the matching of frequency characteristics of the SLED power compression systems, accelerating sections and the master oscillator, as well as the selection of the timing and amplitude of the injected beam.
