摘要
用蒙特卡洛方法来讨论束参量（半径、发射度和能量）对韧致辐射照射量的影响。结果表明，当束击靶半径一定时，靶正前方一米处的照射量Ｘ＿１随发射度增加而减小；当发射度一定时，照射量先随半径增加而急速增加，在束半径大于Ｒ＿（ｂｍ）后，随半径进一步的增加而缓慢降低。也研究了束参量对照射量角分布的影响。因为使用了电子束的Ｋ－Ｖ分布，所得Ｘ＿１值是偏于保守的。
Effects of electron beam parameters,including radius,emittance and en-ergy, on bremsstrahlung exposure are discussed in this paper.It is shown that, in fixed beam radius,the larger the beam emittance,the smaller the exposure X_1at 1m in front of the target,and that in fixed emittance,the exposure quickly increases when the beam radius increases from 0 to R_(bm)then it slowly decreases as the radius becomes large fur-ther.Effects of them on angular distribution of the exposure are also exposed. Because of using K-V beam distribution,the results for X_1 are conservative,
