A device for controll- ing beams of particles, X- rays and gamma rays in- chiding a plurality of chan- nels with total external ref- lection inner surfaces, input butt-ends facing a radiation source and output butt-ends aimed at a radiation receiv- er is taught. Channel-farm- ing elements are in the form of surfaces, tubes, and struc- tures with multiple channels one are rigidly positioned one relative to mother with a spacing between suports such that the sagging of the channel-foaming elements does not interfere with beam propagation The de- vice can be used to capture radiation from sources which produce parallel or divergent radiation. The resulting beam or beams can be of a variety of shapes or angular orientations including quasi-parallel, convergent, and split beams. Energy filtering is accomplished by selective absor- tion of radiation by the channel-forming elements and by selective reflection, by geometrics which cause some energies to be dis- criminated against because of the angle of total external reflection associated with that energy. Also provided are embodiments which use these devices for improved medical imaging, medical therapy, X-ray lithography, and analytic instruments.
