FIG. 1.

The proton beam intensity at the source as a function of the preplasma density gradient scale length. Solid line—an approximation of the results of PIC simulations (points); dashed line—the result of calculations using the momentum-conservation model. See the text for details.

FIG. 2.

Angular distributions of the proton beam intensity obtained from (a) IC measurements, (b) simulations, and (c), (d) RCF. For the simulation, , , and a hydrogen plasma of , and the peak density of 10 was assumed. The RCF records concern protons of .

FIG. 3.

The (a) proton beam power and (b) intensity at the source as a function of laser intensity. Points with error bars—the results of IC measurements; lines—the results of approximation by a power function. Points without error bars—the results of PIC simulations, in which a super-Gaussian 0.35 ps laser pulse interacted with an inhomogeneous hydrogen plasma layer of the density profile shown in Fig. 1 with .

FIG. 4.

A comparison of the proton beam intensity at the source and the laser-protons energy conversion efficiency for Au/PS and PS targets. .

Image of FIG. 5.
FIG. 5.

Laser-protons energy conversion efficiency as a function of laser intensity for PS and Au/PS targets. Points—the results of IC measurements; lines—the results of approximation by a power function.

Image of FIG. 6.
FIG. 6.

A comparison of the proton energy spectrum in the high-energy range for Au/PS and PS targets. Points—the results of SSTD measurements; lines—the results of approximation by the Maxwellian energy distribution with the temperature .
