It is necessary to change magnetic field vectors in dipole magnets to deliver particles which have different charges, such as positrons and electrons. Because of some physics effects in order to achieve precise adjustment of field, it is better to register not only current in magnet coils, but also the field in the transportation channel of the injection complex itself. The aim of the work is development of the device which would measure a magnetic field in the injection complex transportation channel with an accuracy better than <span>({{10}^{{ - 3}}})</span>. Hall effect method is chosen. The tests on Hall sensors resistance to radiation are conducted. The device prototype for this experiment is created, assembled and tested.

The main purpose of testing is to identify hidden defects that may arise under critical loads on the equipment. There are various empirical methods described in production standards used to detect equipment failures. The paper presents an automated system for testing server equipment, including automation of system installation, launching tests, and collecting test logs. In the current implementation of the system, testing is carried out using the method of Highly Accelerated Stress Screening (HASS). A key part of the system is the monitoring subsystem required for collecting and analyzing temperature data from the tested components. Temperature metrics analysis during the testing phase allows to determine the duration of testing with a given accuracy. In addition to the monitoring tools such as Node Exporter, Prometheus, Prometheus Gateway and Grafana, the system uses Stress-ng to load the equipment with synthetic tests. All of these subsystems are freely distributed, and the proposed system can be easily implemented for similar testing in comparable infrastructures.</p>","PeriodicalId":730,"journal":{"name":"Physics of Particles and Nuclei Letters","volume":"22 5","pages":"1015 - 1018"},"PeriodicalIF":0.4,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
