The idea and a performance test for detection of highly ionizing particles such as magnetic monopole with fine grain nuclear emulsion is presented. The fine grain emulsion named Nano Imaging Tracker (NIT) developed for dark matter search is considered to use as Emulsion Cloud Chamber (ECC) with standard emulsion in such an experiment. NIT is less sensitive for minimum ionizing particles (MIP) and measure energy deposition by highly ionizing particles without counting d rays. While MIP sensitive standard emulsion measure the particle velocity by δ rays activities. The particle velocity and corresponding charge z estimated by the energy deposition are expected to be measured with the ECC. A test exposure to 13A GeV and 150A GeV lead beam at CERN was carried out and the aimed performance was confirmed that only core of trajectory of lead ions are recorded in NIT. Thanks to very good spacial resolution, lead ion interaction products can be seen even two tracks separation within one mm. The vertically exposed NIT films can be readout with recent high speed automated track selector. The results of the test exposure shows a large area O(1000m2) ECC detector for search of exotic particles having high energy deposition can be possible.
