64. Overview of the Radiation safety on RAON

INSEOK HONG (IBS)

10/20/26, 9:20 AM

Oral

The heavy ion accelerator consists of an ISOL and an IF system, where the ISOL produces rare isotopes using a 70 MeV proton beam and is configured so that they can be re-accelerated by the IF system. In the IF system, for the stable isotope U-238, the maximum beam energy is 200 MeV/u. Currently, a cyclotron-based ISOL system and a low-energy superconducting accelerator are in operation, and...

28. The Facility for Rare Isotope Beams: Radiation Transport Supporting Power Ramp-Up

Juan Zamora (Facility for Rare Isotope Beams)

10/20/26, 9:40 AM

Oral

The Facility for Rare Isotope Beams (FRIB) serves as the world’s most powerful heavy-ion accelerator. Currently operating at 20 kW, plans are underway to increase beam power by a factor of 20.
In operation since 2022, FRIB produces rare-isotope beams through in-flight fragmentation of high-power beams of stable heavy-ion isotopes ranging from oxygen to uranium at energies up to 200 MeV per...

3. Shielding Calculations for PETRA IV Beamlines using FLUKA Monte Carlo Code

Leila Mokhtari Oranj (DESY)

10/20/26, 10:00 AM

Oral

In recent years, a new fourth generation of light sources has emerged based on advanced storage-ring lattice concepts. This new approach enables a significant reduction in horizontal emittance compared with existing facilities. PETRA III at DESY is one of the brightest synchrotron radiation sources worldwide, serving a broad international and multidisciplinary user community through 25...

27. Swap-Out Safety Analysis Methods for the ALS-U Project

Stefania Trovati (Lawrence Berkeley National Laboratory)

10/20/26, 10:35 AM

Oral

The Advanced Light Source Upgrade (ALS‑U) project at the Lawrence Berkeley National Laboratory (LBNL) requires a comprehensive evaluation of a swap‑out incident, defined as an errant electron beam being injected into a photon beamline and subsequently lost, resulting in potentially unacceptable radiation dose levels on the experimental floor. Historically, for the currently operated ALS...

30. Radiation Protection, Power and Beam Loss Management for the SLAC Linac Coherent Light Source-II High-Energy Upgrade (LCLS-II-HE)

Jan Blaha (SLAC National Accelerator Laboratory)

10/20/26, 10:55 AM

Oral

The Linac Coherent Light Source II High-Energy (LCLS-II-HE) upgrade at SLAC extends the superconducting radiofrequency linac from a nominal beam energy of 4 GeV to 8 GeV, doubling available beam power to approximately 240 kW and enabling expanded free-electron laser capability. The higher beam energy produces harder and more forward-peaked electromagnetic showers, which can elevate dose rates...

32. Radiological Commissioning of the LCLS-II CW Superconducting Linac: Shielding Validation and Radiation Monitor Performance

Thomas Frosio (SLAC)

10/20/26, 11:15 AM

Oral

The Linac Coherent Light Source II (LCLS-II) at SLAC is a continuous-wave (CW) superconducting radiofrequency (SCRF) electron linac that accelerates electrons to about 4 GeV at MHz repetition rates, with a design beam power of 120 kW and a maximum credible beam power of 1.2 MW. Radiological commissioning advanced through staged beam destinations: halo collimators along the linac, the Beam...
