This invention describes a system for generating multiple simultaneous tunable electron and photon beams and monochromatic x-rays for all field simultaneous radiation therapy (AFSRT), tumor specific AFSRT and screening for concealed elements worn on to the body or contained in a container. Inverse Compton scattering renders variable energy spent electron and tunable monochromatic x-rays. It's spent electron beam is reused for radiation with electron beam or to generate photon beam. Tumor specific radiation with Auger transformation radiation is facilitated by exposing high affinity tumor bound heavy elements with external monochromatic x-rays. Heavy elements like directly iodinated steroid molecule that has high affinity binding to estrogen receptor in breast cancer and to iodinated testosterone in prostate cancer or with directly implanted nanoparticles into the tumor are exposed with tuned external monochromatic x-rays for tumor specific radiation therapy. Likewise, screening element's atom's k, l, m, n shell specific Auger transformation radiation generated by its exposure to external monochromatic x-rays is used to screen for concealed objects. Multiple beam segments from a beam storage ring or from octagonal beam lines are simultaneously switched on for simultaneous radiation with multiple beams. The beam on time to expose a tumor or an object is only a few seconds. It also facilitates breathing synchronized radiation therapy. The intensity modulated radiation therapy (IMRT) and intensity modulated screening for concealed objects (IMSFCO) is rendered by varying beam intensities of multiple simultaneous beams. The isocentric additive high dose rate from simultaneously converging multiple beams, the concomitant hyperthermia and chemotherapy and tumor specific radiation therapy and the AFSRT's very low radiation to the normal tissue all are used to treat a tumor with lower radiation dose and to treat a radioresistant and multiple times recurrent tumors that heave no other alternative treatments.
