“…Figure 11 shows the calculated potential well and the corresponding synchrotron tune at the 14400th turn at the extraction energy based on Eqs. ( 8)- (12). Considering the symmetry, we can merely calculate the synchrotron tune between 0 and .…”

“…There are 10080 bunches in total for one of the two collider rings, each containing 1.510 11 particles, to achieve the nominal luminosity of 110 35 cm -2 s -1 . The instant luminosity could be even higher when some luminosity leveling methods are applied [12]. This will pose severe challenges on the detector design and data analysis methods that will allow us to record the data first and extract the interesting physics events afterwards.…”

The High Energy cosmic-Radiation Detection (HERD) facility is a future space mission, scheduled to start its operation around 2027 aboard the China's Space Station. Thanks to its novel design, based on a homogeneous, isotropic and finely-segmented 3D calorimeter, the detector will have a good particle energy resolution and a large effective geometric factor. With these specifications, the experiment is expected to extend the direct measurements of cosmic rays and gamma rays by at least one order of magnitude in energy with respect to the current limits. In such a way, the space mission aims to accomplish important and frontier goals relative to dark matter search, cosmic ray observations and gamma ray astronomy. In this contribution, a review of the current status of the experiment is presented, with particular regards to the estimated detector performances and the expected physics results. *** 27th European Cosmic Ray Symposium -ECRS *** *** 25-29 July 2022 *** *** Nijmegen, the Netherlands *** on behalf of the HERD Collaboration * Speaker

“…The study on the dynamic aperture at the SPPC shows that the beam-beam interactions are the most influential factor, including both parasitic interactions and head-on interactions [15,22]. Non-linear forces from parasitic interactions are usually more important in the reduction of dynamic aperture, but the large tune shift from head-on interactions will cause the resonances driven mainly by non-linear magnetic fields.…”

Following the discovery of the Higgs boson at the LHC in 2012, new large colliders are being considered and studied by the international high-energy community to explore the Higgs boson in details and to probe new physics beyond the Standard Model. In China, a two-stage circular collider project, CEPC-SPPC was proposed and is under study. The first stage, CEPC (Circular Electron Positron Collier, a so-called Higgs factory) is focused on the Higgs physics, and the second stage, SPPC (Super Proton-Proton Collider) will be an energy frontier collider and a discovery machine beyond the LHC. The two colliders will share a same tunnel of 100 km in circumference, with a goal of 250 GeV in center-of-mass for CEPC and 75 TeV for SPPC Phase-I and 125–150 TeV for the SPPC ultimate goal. This article presents the design concept of the SPPC and some study results about the key accelerator physics problems and technical issues, which include luminosity optimization, beam collimation, beam-beam effects, longitudinal beam dynamics, high-field magnets and beam screen.
