Abstract :
The Rotating Modulation Collimator has been modified to image thermal neutron sources. The components of the RMC imaging system were modified to suit thermal neutrons. The experiment compared two detectors (He3 and BF3) and two mask materials (cadmium and borated epoxy) for a 77mCi PuBe source. Preliminary results indicate that both He3 and BF3 detectors may be used with the RMC. Further efforts will be made to reduce the uncertainty in the system.
