Abstract
A charged particle beam generating apparatus irradiates an article on all sides thereof by scanning the beam across the article and magnetically curving the beam, when scanned away from the article, to the back side of the article. The magnetic structure provides a magnetic field normal to the scanning direction with a field intensity that is greater near the article than it is further from the article. This results in more nearly uniform irradiation of the entire peripheral surface of the article.
