The reflector has a paraboloid shell (1) for defining a surface (3) that reflects X-rays, and exhibiting thickness of an absorbent material (5), which absorbs X-rays that are not totally reflected by the reflective surface. The absorbent material includes lead or uranium ore particles bagged between metal sheets (11, 13). The shell includes an input section (7) and an output section (9) closed in gas-tight manner when being crossed by the X-rays. The reflective surface includes a metal sheet (2) i.e. uranium sheet, pressed against the shell by introducing gas (15). |
