An analytical approach of thermodynamic behavior in a gas target system on a medical cyclotron

Appl Radiat Isot. 2016 Jan:107:252-258. doi: 10.1016/j.apradiso.2015.10.033. Epub 2015 Nov 2.

Abstract

An analytical model has been developed to study the thermo-mechanical behavior of gas targets used to produce medical isotopes, assuming that the system reaches steady-state. It is based on an integral analysis of the mass and energy balance of the gas-target system, the ideal gas law, and the deformation of the foil. The heat transfer coefficients for different target bodies and gases have been calculated. Excellent agreement is observed between experiments performed at TRIUMF's 13 MeV cyclotron and the model.

Keywords: Gas target; Medical cyclotron; PET isotopes; Thermodynamical model.
