Pol. Lt. Gen. Pornchai Suteerakune, NIMT Director, warmly welcomed Mr. Kamoliddin MAKHAMATOV, Senior Scientist from the DC Resistance, Power and Energy Laboratory of the Uzbek National Institute of Metrology (UzNIM), Republic of Uzbekistan, who participated in the Calibration of Magnetic Field Strength Meters training programme held at NIMT from 13–24 July 2026.

The training programme was organized in collaboration with Physikalisch-Technische Bundesanstalt (PTB), Germany, under the project “Support to the Reform of the National Quality Infrastructure in Uzbekistan Phase II.” The two-week programme combined lectures and hands-on practical training covering the principles of magnetic flux density measurement, calibration techniques for magnetic field strength meters and reference magnets, magnetic field generator and Helmholtz coil calibration, as well as measurement uncertainty evaluation and reporting.

Through this programme, NIMT continues to share its technical expertise and contribute to capacity building for national metrology institutes, reinforcing international collaboration and promoting reliable and traceable measurements in support of quality infrastructure.

Mrs. Yaowaret Pimsut, from NIMT, successfully completed a research attachment at the Physikalisch-Technische Bundesanstalt (PTB), Germany, from 24 April to 19 July 2026. The attachment was conducted under the long-standing collaboration between NIMT and PTB and focused on the development and evaluation of a Programmable Josephson Voltage Standard (PJVS)-based Quantum Voltmeter (QVM) for direct SI-traceable AC-DC transfer difference measurements.

During the three-month attachment, Mrs. Yaowaret worked closely with PTB researchers to enhance the performance of the quantum voltage measurement system. Her work included improving the LabVIEW control software by implementing automated measurement routines, signal verification, data acquisition, and configuration management to increase the efficiency and reliability of the measurement process. She also participated in a series of experimental investigations to evaluate different measurement configurations, grounding arrangements, switching systems, and noise reduction techniques to improve the accuracy and stability of the PJVS-based measurement system.

The research contributed to a better understanding of the factors affecting the performance of quantum-based AC-DC transfer measurements and identified practical approaches for improving measurement reproducibility. The knowledge and technical experience gained during this attachment will support the further development of quantum metrology at NIMT, strengthen Thailand’s national measurement capabilities, and reinforce the long-standing collaboration between NIMT and PTB in advancing measurement science and innovation.

Mr. Anusorn Tonmueanwai, Deputy Director of NIMT, together with Mrs. Surat Leeudomwong, Ms. Panisara Kongthavorn, and Mr. Nattapong Paenoi, participated in the 32nd International Congress on Sound and Vibration (ICSV 32) held in Istanbul, Republic of Türkiye, from 4–12 July 2026.
