Ion beam intensity distribution in ion-bombarded areas of biological targets

The ion beam intensity distribution in an ion-beain-bombarded area is particularly important for treating biological targets that are location-sensitive to ion energy and fluence. In order to investigate the beam intensity distribution, we carried out a theoretical calculation. The theoretical study...
