We introduce our handmade image intensiˆer for visualizing the beam proˆles of accelerated ion beams having energy and current in the order of keV and nano-amperes, respectively. The simple image intensiˆer comprising stainless steel meshes and a ‰uorescent screen has been designed for the transport of mm-size ion beams. The intensiˆer is easy to install in the beamline of a vacuum setup, because it is designed to attach on a con‰at ‰ange of ICF70. We have used the image intensiˆer to observe

... e beam proˆles of the ion beams transported from the ion source to an ultra-high vacuum chamber. Through the use of the image intensiˆer, bright images were obtained, and it was concluded that the intensiˆer is useful for observing the proˆles of the beams having current densities greater than 0.1 nA mm -2 .
