The Heavy Ion Laboratory participated in the first day of the 6th Polish‑British Science Forum, which this year was hosted by the University of Warsaw. The Director of HIL, Paweł Napiorkowski, presented to the guests from the United Kingdom the accelerator facility operating at the University of Warsaw and its importance for the European Research Area. Particular attention was given to the Laboratory’s extensive international cooperation in nuclear physics research and applications, as well as the use of the Warsaw Cyclotron for training students and young researchers from Poland and abroad. A brief visit of the Forum participants to the Laboratory allowed them not only to see the research infrastructure available at HIL, but also to meet the international research team led by Dr. Desislava Kalaydjieva from Canada and Dr. Marco Siciliano from the United States. The researchers were conducting measurements using the beam of the Warsaw Cyclotron at the time. The Deputy...

We are pleased to invite you to the upcoming HIL seminar, which will take place on Wednesday, March 25, 2026, at 12:15 (CET) in the library. Dr. Bahadır Saygı from Ankara University will give a lecture: "A Photopeak-Bayesian Isotope Identifier for Radiation Portal Monitors Using a Medium-Resolution CeBr₃ Detector" Abstract: Radioisotope Identification Devices (RID) play an essential role in applied nuclear physics, particularly in nuclear security and safeguards, where the rapid and reliable characterization of radioactive materials is crucial. In real-world field conditions, however, identifying radionuclides in real time—without relying on expert spectral interpretation—remains challenging. Peak overlap, counting statistics, and complex background structures often complicate the analysis of gamma-ray spectra. In this talk, I will describe the development and experimental validation of an automated real-time isotope identification algorithm designed to address these challenges. The approach combines second-derivative-based peak enhancement with a Bayesian, photopeak-centered decision framework. Peak detection is carried out using a Mariscotti-type method, allowing statistically significant gamma-ray photopeaks to be identified in a robust manner. Isotope attribution is...
