  As the second phase of CEPC-SPPC project, SPPC (Super Proton-Proton Collider) is to explore new physics beyond the standard model in the energy frontier with a center-of-mass energy of 75 TeV. In order to handle extremely-high stored energy in beam, the collimation system of extremely high efficiency is required for safe operation. SPPC has been studying a collimation method which arranges both the transverse and momentum collimations in one long straight section. In this way, the downstream momentum collimation section can clean those particles related to the single diffractive effect in the transverse collimation section thus eliminate beam losses in the arc section. In addition, one more collimation stage is obtained with use of special superconduct-ing quadrupoles in the transverse collimation section. Multiple particle simulations have proven the effectiveness of the methods. This paper presents the study results on the collimation scheme.

We report the beamline design of the Experimental Muon Source (EMuS) project in China. Based on the 1.6 GeV/100 kW proton accelerator at the Chinese Spallation Neutron Source (CSNS), EMuS will extract one bunch from every 10 double-bunch proton pulses to hit a stand-alone target sitting in a superconducting solenoid, and the secondary muons/pions are guided to the experimental area. The beamline is designed to provide both a surface muon beam and a decay muon beam, so that various experiments such as muSR applications and particle/nuclear physics experiments can be conducted. In this work we present the conceptual design and simulation of the beamlines, and discuss the future aspects of the project.
