The Super Tau-Charm Facility (STCF) was proposed as a third-generation circular electron-positron collider in the energy range of 2-7 GeV (CoM) and with a luminosity greater than 5*10^34 cm^-2s^-1 @4 GeV, aiming to explore charm physics and tau physics in the next decades. This presentation will introduce the facility design and R&D efforts for STCF, including the design goal, accelerator and...
In this talk the status of CLIC will be reviewd on design, technology readyness, human resourcece and timeline, etc.
The Ghost Collider is a proposal for a 550 GeV center-of-mass (275 GeV per beam) linear collider with four interaction regions, each with the design luminosity. The primary innovation is the use of “ghost bunches” containing equal numbers of electrons and positrons, therefore being electrically neutral. In the linacs, energy is transferred between electrons and positrons in the same bunch,...
The BNL Relativistic Ion Collider (RHIC) started operation in 2000 with a program of high-energy ion collisions. A few years later a unique program with polarized proton collisions was added, and the following years the program expanded further and further with the Au-Au luminosity increasing to 44x of the Au-Au design using a with novel bunched beam stochastic cooling system, proton...
We propose Near Resonance Polarization Modulation (NRPM), a novel method for high-precise beam energy measurement in storage rings. In this technique, a constant-frequency AC kicker is applied near the spin precession frequency, driving the beam spins coherently. The spin tune can be reliably extracted from the time-dependent polarization signal, enabling a very high-precision determination of...
The Large Hadron Collider (LHC) run in 2025 was the last long production year of LHC Run 3 (2022 to 2026). To mitigate potential radiation damage to magnets installed in the low-beta sections due to the integrated radiation dose near the high luminosity experiments, a flat optics was used for the first time in beam operation, underlying the adaptability of the LHC. A record production of 125...
