TAN Target Absorber Neutral: absorber for the neutral particles leaving the IP. It is located just in front of the D1 separation / recombination dipole magnet on the side facing the IP.
TAS Target Absorber Secondaries: absorber for particles leaving the IP at large angles. It is located just in front of the Q1 triplet quadrupole magnet on the side facing the IP.
Tune Number of particle trajectory oscillations during one revolution in the storage ring (transverse and longitudinal).
Triplet Assembly of three quadrupole magnets used for a reduction of the optical β-functions at the IPs. The LHC triplet assembly consists in fact of 4 quadrupole magnets but the central two quadrupole magnets form one functional entity. The LHC has triplet assemblies in IR1, IR2, IR5 and IR8.
