Title:
低速陽電子パルスビーム装置
Document Type and Number:
Japanese Patent JP4340773
Kind Code:
B2
Abstract:
To provide a positron beam device which has a beam strength equal to or more than that when tungsten is used as a moderator, can also generate a slow positron beam whose energy distribution is in a narrow range and allows an alternative to tungsten to be used as a moderator.
A crystallized nickel mesh is used as a moderator 2. It is preferable that the nickel mesh is composed of a nickel solid wire whose diameter is between 1 μm and 100 μm. It is more desirable that the nickel solid wire is made by narrowing its linear diameter through the etching with an acid liquid solution.
