Extended Data Fig. 3. Target reconstruction.
Reconstructed reaction vertex with the liquid-hydrogen target in ZX (a), ZY (b), and XY (c) planes. The cylindrical shape of the target is visible with a thickness of ~ 50 mm, where the first silicon plane in these plots is located at z = 0 In x- and y-directions, the vertices are Gaussian distributed with a cutoff according to the target cell radius. In y–direction a lower upper cutoff is visible, indicating that the target cell was not completely filled by liquid-hydrogen
