| Abstract: | The photon attenuation effects are different, when the photons with different energy pass through the attenuators with different thickness and material. Using the above attenuators and the thermoluminescent probes, the degrader detector was designed for detecting the gamma spectrum of the fast reactor. Meanwhile the unfolding Program is programmed for the continuous spectrum in GRAVEL algorithm, and this program is proved reliable by experimental results. Finally, the photon spectrum of the fast reactor is given. |
