Inference of joule-class THz radiation sources from microchannel targets driven with hundreds of joule, picosecond lasers is reported. Here, THz sources of this magnitude are useful for nonlinear pumping of matter and for charged-particle acceleration and manipulation. Microchannel targets demonstrate increased laser–THz conversion efficiency compared to planar foil targets, with laser energy to THz energy conversion up to ~0.9% in the best cases.
