The ILC provides an extremely high energy electron beam with an excellent beam divergence. Thus, a linearly polarized photon beam of about 75 GeV can be produced by coherent bremsstrahlung using a thin diamond radiator. Thanks to the electron beam polarization, it is also possible to generate a circularly polarized photon beam. Such a very high energy photon beam would be useful to produce...
The International Linear Collider (ILC) will have electron and positron beam energies above 125 GeV. High intensity lasers have achieved unprecedented intensities of $10^{23}$ W/cm$^2$. Although typically such lasers have photons with energies in the eV range in the laboratory frame, colliding such high intensity lasers and the ultrahigh energy electron and positron beams of the ILC will...
Conventional muon beams are produced using proton beams and are used in material sciences such as $\mu$SR and elemental analysis, and fundamental physics experiments such as muon g-2 measurements and precision measurements of muoniums. These muon beams have high intensity but poor emittance, and their kinetic energies are $O$(1) MeV. On the other hand, muon beams with a low emittance on the...
Neutrons are widely used for material sciences, imaging, fundamental physics and so on due to its unique properties. Recently, spallation neutron sources using megawatt class accelerators are coming up as next-generation neutron sources instead of research reactors. A spallation neutron source irradiates proton beam with energy of a few GeV into a neutron spallation target made of a heavy...
Medical RI production is a very promising application of superconducting (SC) linear accelerator. SC LINAC can easily generate large averaged current beam of higher energy than those from industrial electron sources for the electron beam (EB) processing where RI production must be avoided. ILC type long pulsed SC LINAC has great cost efficiency due to low duty factor where RF heat load can...
The LUXE experiment (LASER Und XFEL Experiment) is a new experiment in planning at DESY Hamburg using the electron beam of the European XFEL. LUXE is intended to study collisions between a high-intensity optical laser and 16.5 GeV electrons from the XFEL electron beam, as well as collisions between the optical LASER and high-energy secondary photons. The physics objective of LUXE are processes...
