      abstract     = {Here we report a laser plasma-driven source of T-rays with
                      the highest pulse energy ever recorded in a laboratory.
                      T-rays are emitted from therear surface of a solid target in
                      the non-collinear direction at incident laser intensities ~
                      $10^19$ $W/cm^2.$ Pulse energy measurements reported T-ray
                      pulses with peak energies no less than 700 μJ. Temporal
                      measurements using a single-shot electro-optic method showed
                      the presence of sub-picosecond T-ray pulseswith 570 fs
                      duration, thus rendering the peak-power of the source higher
                      even than that of state-of-the-art synchrotrons. A
                      conversion efficiencyof higher than $10^-3$ and an average
                      power of 7 mW makes it the most efficient compact and
                      powerful THz source known today. Spectral analysis revealed
                      the presences of frequencies ranging from 0.1 - 133 THz,
                      while most of the energy is localised in the low frequency
                      region. The dependence of T-ray yield on incident laser
                      energy is linear and shows no signs of saturation. The
                      spatial distribution of the recorded T-rays indicates that
                      most of the T-rays are emitted in the non-collinear
                      direction from the rear-surface of a solid target and the
                      contribution in the forward direction is very small. 2D
                      particle-in-cellsimulations show the presence of transient
                      current at the target rear surface.},
