Title:
NUCLEAR FUSION TARGET, NUCLEAR FUSION DEVICE, AND NUCLEAR FUSION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/074612
Kind Code:
A1
Abstract:
Disclosed is a device which is capable of inducing a nuclear fusion reaction with relatively high efficiency, while being reduced in size. Specifically disclosed is a nuclear fusion device (1) which comprises: a nuclear fusion target material (7) that comprises a target substrate (7a) containing deuterium or tritium, and a thin film layer (7b) arranged on the target substrate (7a) and containing deuterium or tritium; a vacuum container (5) that houses the nuclear fusion target material (7); and a laser device (3) that emits two successive first and second pulse laser beams (P1, P2) toward the thin film layer (7b) of the nuclear fusion target material (7). The intensity of the first pulse laser beam (P1) is set at a value that is lower than the intensity of the second pulse laser beam (P2) but capable of separating the thin film layer (7b) from the target substrate (7a).
