Abstract
A efficient point source x-ray target tape assemble. A tape is wrapped helically around a rotating drum a little more than one complete turn so as to create an overlap section where a section of the tape is positioned parallel and adjacent to a separate section of the tape. The tape advances slowly across the outside surface of the drum at a speed which is a small fraction of the tangential surface speed of said drum. In a preferred embodiment a pulsed laser beam is focused on the tape at a fixed spot in space through which the tape moves in order to create x-rays from plasma generated by very high intensity ablation of the tape material. The combination of the drum rotation and the tape advancement across the surface of the drum permits substantially full utilization of the tape material for generation of x-rays.
Claims7
An X-ray target tape system comprising:
- A) a tape drum defining a tape drum outside surface and a circumference,
- B) a drum rotating means for rotating said drum,
- C) a tape having a constant width, wrapped helically around said tape drum at least slightly more than one complete turn so as to define an overlap section such that a first section of said tape is positioned parallel to a second section of said tape,
- D) a tape advancing means for advancing said tape across the outside surface of said drum at a speed which is a small fraction of the tangential surface speed of said drum, the distance traveled by sections of said tape on the outside surface of said rotating drum defining an overlapping tape path, and
- E) a laser producing a laser beam focused on a fixed spot located on said overlapping tape path of said tape so as to ablate portions of said tape to produce x-rays.
