In order to realize a non-destructive and fast-response beam profile monitor for stable operation of the accelerators in the J-PARC, we have been developing a dense gas-sheet target with the aid of vacuum science and technology. After the study with the Monte Carlo simulations of transported molecules through some kinds of tubes, the deep slit is found to be effectual to make a gas sheet. In this report, the outline of the simulations will be shown, and the performances of the proto-type gas sheet generator will be presented through the demonstration experiments for the electron beam detection.
