Dynamic Aperture Tune Scan for LHC Version 5 at Injection Energy

For the LHC lattice Version 5, 6D tracking studies have been performed at injection energy over a wide range of fractional tunes and for three different distances from the tune diagonal (Qx - Qz - 0) The aim was to find optimal pairs of tune. to this end 100o turn tracking was performed for 60 different representations of the dipole and quadrupole errors. In tune regions with largest short-term dynamic apertures the tracking has been prolonged to 100 000 turns to confirm the long-term particle stability at these pairs of tunes
