| Outline of Final Research Achievements |
Ion beam was injected into a thin straight insulating tube (capillary) of various materials, and the change in ion transmission (tilt angle dependency = guide effect) was measured by tilting the capillary. As a result, we found that a capillary made of soda-lime glass is optimal as an ion guide for low energy multiply charged ions. Therefore, we made a gently curved soda-lime glass capillary, injected the ion beam into the capillary, and measured the guide effect and transport efficiency. It was found that with a curved capillary the ions can be transported (guided) into an angle more than twice as large as in the case of tilting straight capillaries of the same length. The possibility of application as a simple ion deflector has come to light.
