The collimation system of the Large Hadron Collider (LHC) at CERN represents the state of the arc of multi-stage collimation systems. It provides an excellent cleaning performance that has so far ensured safe and efficient operation of the LHC with beam stored energies up to 430 MJ. However, further improvements are needed in view of the High-Luminosity upgrade of the LHC (HL-LHC) that will...
ISIS is the pulsed, spallation neutron and muon source at the Rutherford Appleton Laboratory in the UK. Its rapid cycling synchrotron accelerates 3e13 protons-per-pulse from 70 to 800 MeV at 50 Hz, delivering a mean beam power of 0.2 MW to its two target stations. The intensity of ISIS is beam-loss limited, so increasing its neutron and muon output requires beam-loss mechanisms to be well...
For the high power spallation neutron sources, the laser-assisted H− stripping is a new essential technology. It can be an alternative to the foil stripping which may be used to overcome various difficulties faced by the stripping foils, such as short lifetime, high temperature, large radiation dose, etc. In this paper, based on the phase II of China Spallation Neutron Source (CSNS-II), the...
