gamma sphere 中文意思是什麼
gamma sphere
解釋
伽瑪射線球-
At first, measuring the electron recoil spectra of target room gamma ray. through the resolution of spectra we get the gamma ray spectra caused by target room. then we transform it to the zero point, the place of neutron source, and calculate the leakage gamma ray spectra t from iron sphere caused by target room gamma ray by mcnp program
靶室產生的射線本底,通過實驗測量和模擬計算相結合的方法加以扣除,首先測量靶室產生的射線康普頓反沖電子譜,解譜得到靶室泄漏譜,將所解得的靶室泄漏譜歸一到原點,即中子源處,利用mcnp蒙卡程序輸運計算靶室射線穿透鐵球后所泄漏的能譜,最後從d ? t中子穿透鐵球伴生射線泄漏能譜s中扣除。 -
The results show that the mass absorption coefficient is nearly exponent decay with the gamma energy, the less energy of gamma ray, the more probability of absorption in the iron sphere
結果表明,隨著射線能量的增加,質量吸收系數近似呈指d一t中子穿透鐵球伴生y射線泄漏能譜實驗研究數衰減, y射線能量越低,被鐵原子核吸收的幾率越大。
