The neutron zooming tube has been developed using electronic zooming TV readout system for an X-ray microscope. This system consists of the photocathode, the electro-magnetic coil assembly and the CCD TV camera etc.. The photocathode consists of transmission type CsI layer in combination with neutron converters such as Gd foil. The system position sensitive resolution of 20m has been obtained using neutron converter. We have found that it is determined from the distance between the CsI layer and the neutron converter, then the limiting resolution could be improved.
