Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
114 words
A method of producing collimated radiation of the x-ray wave length comprising; obtaining a laser operable to produce a pulse of laser radiation in the near infrared spectrum; orienting a focusing system so as to focus the pulse of laser radiation into a linear beam; placing a layer of metallic ions in the focal range of the focusing system with the plane of the layer being transverse to the plane of the beam, the angle of the layer being between 6* and 25* to the axis of the beam; and triggering the laser so as to cause a pulse of laser energy to excite the metal ions thereby generating a collimated beam of x-radiation.
Claim 2
Independent Claim
114 words
