High-activity water (HAW) generated during proton-beam operation represents an important source of residual radiation at high-power accelerator facilities. At the TRIUMF ARIEL proton target station, activated cooling water associated with the beam dump and medical-target components can contribute to radiation fields in the Target Preparation and Service Room (TPSR) and adjacent accessible...

When an accelerator facility is constructed, an architectural drawing is written based on shielding calculation results. Although shielding calculation and architectural design work separately, communication in design process between them is important to build a reasonable and easy-to-use accelerator facility. If communication is poor, the facility may be inconvenient layout which is a...

Ozone can be produced when synchrotron white beams interact with air, but reported G-values vary with irradiation conditions and experimental configuration. In this preliminary study, ozone production was measured in a sealed air chamber using a bending-magnet white beam at four opening angles (0.177-0.5 mrad). The absorbed energy in air was calculated from the white-beam spectrum and air...

Synchrotron radiation is generated when a high-energy electron beam passes through an insertion device — an undulator or a wiggler — that provides a periodic magnetic field. Because the electron trajectory is governed by this field, the magnetic properties of the device, such as field strength and period, directly determine the intensity, wavelength, and directionality of the emitted...

Environmental radiation monitoring systems are required to provide reliable information on changes in ambient radiation levels and to support the early detection of abnormal radiological events. However, conventional monitoring systems mainly rely on dose-rate measurements, which provide limited information for identifying the origin of radiation level variations. This study presents a...

KEK and CERN have shared a common interest in radiation safety at high-energy accelerators. To place this cooperation on a durable and operational footing, the two organisations concluded — within the general framework of their Agreement on Collaborative Work (ICA-JP-0103) — a dedicated implementing appendix (KN6005/HSE, Appendix 28) on the Research and Development of Radiation Protection for...

In 2023, Institute for Rare Isotope Science (IRIS) successfully conducted a commissioning test using Rare isotope Accelerator complex for ON-line experiments (RAON) to accelerate a heavy-ion beam to low energy and transmit it to the experimental area. Prior to official operation, the facility must pass a regulatory inspection. In particular, the shielding design section validates the...

One of the tasks of the Radiation Protection (RP) group at CERN is to provide forecasts on the radiological classification of the areas within the main LHC experiments (ALICE, ATLAS, CMS, LHCb) and forecasts on the residual dose rates due to the induced radioactivity from the proton-proton and ion-ion collisions. These forecasts can be performed due to a knowledge of the expected luminosity to...

The SOLEIL II storage ring upgrade project [1, 2] is ongoing and aims at reducing drastically the horizontal emittance of the electron beam from 4 nm.rad for the present ring down to 80 pm.rad for the SOLEIL II new 4th generation storage ring light source. The corresponding long shutdown is scheduled between end of 2028 and end of 2030, when user operation will resume. The first half year will...
