Abstract:
A method of cleaning an inner wall surface (502) of a bell jar (500), by causing nozzles (112, 122) to discharge a cleaning liquid which contains abrasive particles, includes the steps of: (a) causing the nozzles (112, 122) to discharge the cleaning liquid at a discharge pressure at which erosion of the nozzles (112, 122), due to the cleaning liquid, occurs by not more than 500 µm / hour; and (b) adjusting a distance between the inner wall surface (502) and the nozzles (112, 122) so that an impingement pressure, at which the cleaning liquid impinges on the inner wall surface (502), secures a pressure at which dirt on the inner wall surface (502) can be removed.
