The Linac Coherent Light Source (LCLS) at SLAC is operating with a normal-conducting Linac (up to 17 GeV, 120 Hz) and a new superconducting Linac (up to 4 GeV, 1 MHz, since 2023). Free Electron Laser (FEL) beams can be generated by two adjustable gap undulators: one for soft X-rays and one for hard X-rays.
FEL beams are capable of damaging materials and the mechanism of the damages from...
In our research, we aimed to uncover the causes leading to the destruction of thin, carbon-backed lithium fluoride (LiF) targets in Li-7 and O-17 fusion measurements. To achieve this, we estimated theoretically the lifetimes of carbon and LiF films, taking into account the effects of sputtering, thermal evaporation, and lattice damage, and compared them with the lifetime observed in the...
The Second Target Station (STS) Project [1] at Oak Ridge National Laboratory (ORNL) is currently working to complete preliminary design of components within the Target Monolith by the end of calendar year 2025. This includes the rotating water-cooled tungsten target, the two liquid hydrogen moderators, and many other components. After the completion of the Proton Power Upgrade (PPU) [2] of the...
Muon production in the multi-TeV muon collider studied by the International Muon Collider Collaboration is planned to be performed with a high-power proton beam interacting with a fixed graphite target. Capturing the emerging pions and muons requires very strong magnetic fields that can only be reached with superconducting solenoids, whose properties are sensitive to long-term radiation...
The Radial Neutron Camera (RNC) is a diagnostic system located in the ITER Equatorial Port #1, probing a poloidal section of the plasma through a set of fan-shaped Lines of Sight (LOS). The RNC is designed to provide spatial and time-resolved measurement of the neutron and α particles source profiles as well as the total neutron source strength, as a result of reconstruction techniques applied...
The Frascati Neutron Generator (FNG) is a 14 MeV neutron source with a maximum strength of 1x10
In applications like nuclear reactors or particle accelerators, mechanical components near a source of radiation develop radiation damage. This typically means a change in tensile properties and fracture toughness, which depends on the radiation dose (commonly measured in ‘displacements per atom’, or DPA). In addition to such radiation hardening, radiation damage can also cause swelling, which...
