Then, hydrogen cluster, hydrogen molecules compose by intermolecular force, is studied as a new target material in japan. It is possible for us to get high energy ions efficiency when we use the substance in Laser driven ion acceleration experiment. Such useful materials is known that the energy got from them depend on the size of hydrogen clusters. That is why it is very important to discover the cluster size distribution and control them. We make automated system of hydrogen cluster size measurement device to control and simplify the measurement. We measure the size of hydrogen cluster by using Mie scattering phenomena. When the beam caused by Mie scattering are got at photomultiplier and the software made by LABVIEW captures the signal in Windows PC, we are able to obtain cluster size distribution. In this study, we write programs by using Visual Basic Script in Motion Manager 6 and automate the measurement device. As the automated system enable us to measure them effectively, we will examine differences in the size of hydrogen clusters produced by varying the conditions such as temperature, pressure, and nozzle shape., ICMaSS2021}, title = {Automatization of cluster size measurement system for laser-driven ion acceleration}, year = {2021} }
