Abstract
SUPERLATTICE CHANNELING RADIATION IS BEING INVESTIGATED AS AN INTENSE, QUASI-MONOCHROMATIC X-RAY SOURCE. A STRAINED LAYER SUPERLATTICE POSSESSES BENT PLANES WHICH ALTERNATE DIRECTION WITH EACH LAYER OF THE SUPERLATTICE CRYSTAL. A HIGH ENERGY CHARGED PARTICLE WHICH IS CHANNELED ALONG A BENT PLANE WILL FOLLOW THE BENDS IN THE CRYSTAL AND THIS OSCILLATION WILL CAUSE IT TO EMIT RADIATION. HIGH ENERGY (10-100 MEV) ELECTRONS CHANNELED ALONG THE BENT PLANES OF A STRAINED LAYER SUPERLATTICE EMIT X-RAY RADIATION IN A SINGLE PEAK OF 10% FULL WIDTH HALF MAXIMUM (FWHM). THIS RADIATION IS COLLIMATED INTO A NARROW BEAM, MORE INTENSE THAN STANDARD CHANNELING RADIATION AND FAR MORE INTENSE THAN THE BACKGROUND RADIATION PRODUCED. THE CHARACTERISTICS OF SUPERLATTICE CHANNELING RADIATION MAKE IT A PROMISING X-RAY SOURCE FOR NON-INVASIVE DIGITAL SUBTRACTION ANGIOGRAPHY, WHICH REQUIRES INTENSE, TUNABLE RADIATION PEAKS.
