We study a method of laser-Compton cooling of electron beams for future linear colliders. Using a Monte Carlo code, we evaluate the effects of the laser-electron interaction for transverse cooling. The optics with and without chromatic correction for the cooling are examined. The laser-Compton cooling for Japan Linear Collider/Next Linear Collider at E₀  =  2 GeV is considered.

The feasibility of a measurement of the partial decay width of the intermediate-mass Higgs boson into two photons at a photon-photon collider is studied by a simulation. The QCD radiative correction for quark pair background processes is taken into account for the realistic background estimation. It is found that the two-photon decay width can be measured with the statistical error of 7.6% with about one year of experiment. The impact of the measurement of the two-photon decay width to look for the new physics beyond is demonstrated.

The parametric x radiation from thick Si single crystals with 0.5–5 mm thickness was investigated at an electron energy of 900 MeV. As the crystal thickness increased, both intensity and angular spread reached a plateau after their increase in the thin crystal region, resulting in more brilliant x rays than Feranchuk and Ivashin’s prediction [J. Phys. (Paris) 46, 1981 (1985)] for thick crystals. This behavior is consistent with the incoherent model proposed in our previous paper [Phys. Rev. Lett. 70, 3247 (1993)].
