Halo particles contribute very little to the luminosity but may instead be a major source of background and radiation. Even if most of the halo will be stopped by collimators,the secondary muon background may still be significant. We study halo production with detailed simulations and analytical estimates in the CTF3 Test Beam Line (TBL), CLIC drive beam and Beam Delivery System. We calculate and simulate particle scattering process like beam-gas elastic and in-elastic scattering.
