Abstract
In this invention, vibrations generated by a freezer from a cooling mechanism for cooling an ion source emitter tip are prevented from being transmitted to the emitter tip as much as possible, while the cooling capability of the cooling mechanism is improved widely. The ion beam device () is equipped with: an ion source housing () provided with an emitter tip () and defining an ion source chamber () supplied with an ionization gas or gas molecules; a gas pot () provided in the ion source chamber () so as to be thermally connected to the emitter tip () and accommodated so as to have no direct physical contact with a cooling stage () of a freezer (); and a spacer () provided on the peripheral surface of the cooling stage () housed by the gas pot () and maintaining a given interval or greater between the peripheral surface of the cooling stage () and the internal peripheral surface of the gas pot ().
