FIG. 1.

Structural diagram of our proposed targets. (a) The symmetric parabolic concave target, (b) extended target, and (c) extended plasma wall target. Here, the , , , and are the distance between two cavities, depth and diameter of cavity, and length of extended part of the target, respectively. For simplicity, we name the three different targets as A, B, and C, respectively.

FIG. 2.

Energy spectra of the protons for different target geometries at (a) and (b) , respectively. The target parameters are shown in text.

FIG. 3.

Spatial distribution of transverse electric field in the (, ) plane at times and , respectively, for different target geometries. Upper row [(a) and (b)] for target A, middle row [(c) and (d)] for target B, and bottom row [(e) and (f)] for target C. The electric field is normalized by , and other parameters are the same as in Fig. 2 .

FIG. 4.

Energy spectra of the protons [(a) and (b)] for target B and [(c) and (d)] for target C with different extended lengths at times and , respectively. Other parameters are the same as in Fig. 2 .
