Paper Abstract

Frequency multiplier in X-ray region has not been reported. This paper proposes to design the x-ray frequency multiplier, which is based on recent discovery of anti- Compton effect of X-rays from polyethylene terepthalate and low density polyethylene. Electronic system of most of the polymeric atom get excited and some electrons recoil when it is irradiated with x-ray in Compton process. When recoil electron transfers its energy partly or fully to incident x-ray photon it produces anti-Compton effect. At high scattering angle about 160°, the wavelength of anti-Compton scattered radiation decreases by 0.047A0 and there is enhancement of frequency. Fixing another polymer crystal at the calculated position of anti-Compton line, the wavelength of re-scattered radiation at 160° can further be decreased by 0.047A0 or thereby enhancing the frequency. This principle of repeated scattering can be used to multiply the X-ray frequency. In general, x-ray absorption depends approximately on Z. while maximum possible diffracting power is proportional to only Z2, where Z is the atomic number. Thus the crystals of polymer are expected to form better monocromator for designing XFM. The production of high energetic and low intense x-ray by XFM may be used in radiotherapy.
