Operating a gas supply device for a particle beam device

Abstract

Operating a gas feed device for a particle beam apparatus includes predetermining a flow rate of a precursor through an outlet of a precursor reservoir containing the precursor to be fed onto an object, loading a temperature of the precursor reservoir, the temperature being associated with the predetermined flow rate, from a database into a control unit, setting a temperature of the precursor reservoir to the temperature loaded from the database using a temperature setting unit, and determining at least one functional parameter of the precursor reservoir depending on the flow rate and the temperature, loaded from the database, using the control unit and informing a user of the gas feed device about the determined functional parameter. Informing the user of the gas feed device about the functional parameter may include displaying the functional parameter on a display unit, outputting an optical signal, or outputting an acoustic signal.
