Beam optimization for boron neutron capture theraphy at thermal column of TRIGA Mark-II research reactor

The thermal column at TRIGA PUSPATI research reactor has an ability to produce thermal neutron. However, the optimization on the thermal neutron flux produced should be performed in order to gain a sufficient thermal neutron for boron neutron capture therapy purpose. Thus, the objective of this stud...
