Welcome To The B N L Tandem Van de Graaff Accelerator
TVDG LET Calculator

This program calculates the Peak LET, Corresponding Energy and Range as well as the LET and Range at the Specified Energy for the Specified Ion in the Specified Target. The Peak LET, Corresponding Energy and Range as well as the LET and Range at the Specified Energy for the Specified Ion in the Specified Target will be returned.
Select your Target from the list
Select your Ion from the list
Enter your Total Ion Energy

Terms and Definitions

LET
Linear Energy Transfer is the energy absorbed by the target through which a particle is traveling per unit length of the track of the particle. For the purposes of this calculator, the LET is expressed in units of MeV/mg/cm2 (Million electron volts per milligram per square centimeter).

Range
The distance a particle of a given energy will travel through the target until it is stopped. For the purposes of this calculator, the Range is expressed in microns.

Peak LET
The maximum value the LET can assume with the specified materials (ion and target).

Energy for Peak LET
The energy at which the Peak LET occurs.
