Abstract: It is to prevent an image drift from occurring caused by a specimen being charged when observing the specimen including an insulating material. A first scan is performed in a predetermined direction on scanning line and in a predetermined sequential direction of scanning lines and a second scan is performed in a scanning direction different from the predetermined scanning direction and in a sequential direction different from the predetermined sequential direction. An image may be created by repeating the process of executing the second scan after executing the first scan and by requiring the arithmetic average of the frames obtained by the second scans. An image may be created by averaging arithmetically at least one frame obtained by the first scan and at least one frame obtained by the second scan.

Abstract: In an RF ion trap, analyte ions are fragmented by applying a moderately high RF storage voltage to the trap. The ions are then excited via dipolar excitation, and after a short time, the ions are forced into a resting state, again using dipolar excitation. The RF storage voltage is then rapidly reduced to a low value thereby making it possible to store small fragment ions produced by ergodic decompositions that occur subsequent to the reduction of the RF storage voltage.

Abstract: A patterned beam of radiation is projected onto a substrate. A reflective optical element is used to help form the radiation beam from radiation emitted from a plasma region of a plasma source. In the plasma source, a plasma current is generated in the plasma region. To reduce damage to the reflective optical element, a magnetic field is applied in the plasma region with at least a component directed along a direction of the plasma current. This axial magnetic field helps limit the collapse of the Z-pinch region of the plasma. By limiting the collapse, the number of fast ions emitted may be reduced.
