The work is part of a set of preliminary studies for Low EMittance Muon Accelerator (LEMMA) Collaboration.
Through a Monte Carlo simulation we study the kinematic features of a low emittance muon beams from e+ e- collisions at centre-of-mass energy just above the μ+ μ- production threshold corresponding to a positron beam of about 45 GeV.
At the end we obtain the hits distribution in the detector plane and the momenta distributions in the laboratory frame for (anti-)muons. Regarding of modeling we assumed a positron beam in which particles are uniform distribuited in a circle and with energies gaussian distributed. An angular smearing is also considered for each particle composing the incident beam. For the taghet we cosider a 6 cm thick Beryllium block and to obtain the hits distribution for μ+ and μ- we assume the presence of a 2 meter long, 1.7 Tesla dipole magnet placed after the target.
All the parameters set in the simulation are easily editable.
