• A forced-convection gas target for the production of [11C]CH4 on a 13 MeV cyclotron was constructed and tested. A small fan was incorporated into the back of the target, which mixes the target gas during irradiation. The effect of the forced convection alone on the target operation and the [11C]CH4 yield was measured. Forced convection improved the target yield by up to 16 ± 4%. In addition, improvement in heat transfer of up to 70% was observed to be a function of fan speed. Operating with forced convection allowed delivery of 21% higher beam currents while still staying in the acceptable pressure rise during irradiation, providing a 25 ± 7% greater yield. •A fan was introduced in a gas target to create forced convection to produce [11C]CH4 on a 13 MeV cyclotron.•Forced convection improved the target yield by up to 16 ± 4%.•Improvement in heat transfer of up to 70% was observed.•Operating with forced convection allowed delivery of 21% higher beam currents.•Up to 25 ± 7% greater yield was possible due to the increased beam current.
