China Spallation Neutron Source Builds Four New Instruments

China Spallation Neutron Source (CSNS) has successfully completed construction of four neutron instruments in recent days. They are: the Engineering Materials Diffractometer (EMD), the Very Small Angle Neutron Scattering instrument (VSANS), the Energy-Resolved Neutron Imaging instrument (ERNI) and the High energy Direct geometry inelastic neutron scattering spectrometer (HD).

650 MHz SRF Cavities with Ultrahigh Accelerating Gradient

Particle accelerators are essential tools for advancing our understanding of the fundamental building blocks of the universe. These devices use radio-frequency (RF) electric field to accelerate charged particles, such as electrons or protons, to extremely high energy, allowing scientists to study the interactions of these particles in ways that were previously unimaginable. One of the key components of particle accelerators is the superconducting radio-frequency (SRF) cavity, which generates the RF electric field to accelerate the particles.

First Results from LHAASO's Dark Matter Search Place Tighter Constraints on Dark Matter's Lifetime

First Results from LHAASO's Dark Matter Search Place Tighter Constraints on Dark Matter's Lifetime

Scientists from the Large High Altitude Air Shower Observatory (LHAASO) have presented roughly 1.5 years of observational data, calculating new limits on the lifetime of heavy dark matter particles that have masses between 10^5 and 10^9 giga-electron volts. The study, entitled “Constraints on heavy decaying dark matter from 570 days of LHAASO observations,” was recently published as a highlight letter in Physics Review Letter.

First Data Release from GECAM Mission

First Data Release from GECAM Mission

On Dec. 10, the second anniversary of the successful launch of the Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM), the first GECAM data release (DR1) was announced by the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences (CAS), the National Space Science Center (NSSC) of CAS, the National High Energy Physics Data Center (NHEPDC), and the National Space Science Data Center (NSSDC). DR1 contains a catalogue of 75 gamma ray bursts (GRBs) and detailed observational data that support scientific users conducting multi-wavelength and multi-messenger observations of GRBs. Following its footprint of releasing real-time burst messages, GECAM is advancing towards its second milestone of providing scientific services for all scientists.
