Abstract: The monitor is composed of a pair of electrodes, a single stage of microchannel plate, a phosphor screen, a CCD camera and a PC computer. To obtain a good uniform collecting field, forming electrodes system is used instead of that with a resistive divider. The readout system is performed by the phosphor screen and the CCD camera because the spatial resolution is not limited by the mechanical structure like the anode strip type and such video display system is very useful for beam studies and operation of the 40 MeV linac. Besides, the design and test results are described in detail.
