A new low-energy beam transport (LEBT) system with a two-solenoid structure has been designed for the CSNS-II accelerator, which will incorporate a superconducting linac. In addition to its conventional functions, such as differential pumping and RFQ phase matching, this LEBT introduces several advanced features. First, the beamline is tilted by 1.8 degrees upstream of the second solenoid,...

The high-energy proton beam experimental station (HPES) planned to be constructed in CSNS-II can provide multi-pulse high-energy proton test beam with an extremely low beam intensity, which has important applications in research fields such as advanced detectors, irradiation effects, and proton imaging. This report introduces the design of the proton beamlines and experimental station of HPES.

The China Spallation Neutron Source (CSNS) is a major facility for neutron science in China, and is currently operating at an averaged beam power of 170 kW with a beam energy of 1.6 GeV and repetition rate of 25 Hz. In 2024, the CSNS Upgrade project (CSNS-II) was launched aiming to improve the average beam power to 500 kW. In the sequence, a number of new instrumentations will be equipped at...

In order to facilitate specialized applications involving broad-band white light neutron and muon sources, the China Spallation Neutron Source (CSNS) plans to construct a Fixed-Field Alternating Gradient (FFAG) accelerator. With the 300 MeV injector of the CSNS-II, the FFAG accelerator will increase the beam energy from 300 MeV to 600 MeV and then to bombard a target, thereby generating the...

The 100 MeV Proton Linear Accelerator (Linac) has been in operation at the Korea Multipurpose Accelerator Complex (KOMAC) since 2013. Four beam lines are regularly used to provide proton beam services to users. In addition, the neutron beam line is ready to start user services after pilot operation. In parallel, the energy upgrade of the proton linear accelerator is also planned. The proposed...

LaPRIS (Laser Plasma RF Ion Source) is a novel ion source that generates plasma by irradiating pulsed gas with an ultrashort laser pulse. The resulting ions are extracted using a radio-frequency (RF) electric field. Due to the spatiotemporal localization of the laser, ion production occurs only within a brief moment, which may enable high bunching efficiency and low emittance. In this...

Compact neutron sources are small scale neutron sources driven by accelerators. They are also called as CANS or compact accelerator-based neutron sources. Unlike large scale neutron sources such as spallation neutron sources and nuclear reactor neutron sources, CANS are low-cost, small-sized, and highly flexible. The drawback of CANS is the neutron flux, which can be several orders lower than...

In order to stably and reliably remove the electromagnetic losses of the superconducting cavity through thermal conduction using cryocoolers, numerical simulations and experimental studies were conducted on the cooling structure and RF performance of the conduction-cooled superconducting cavity. Based on the geometric structure and electromagnetic losses of the 1.3 GHz superconducting cavity,...
