Description

In Brookhaven National Laboratory (BNL), a collider experiment having same mass number and different charge number atoms is planned at RHIC (Relativistic Heavy Ion Collider). Specifically, it is planned to investigate the influence due to the difference in charge number by comparing $^{96}$Zr atoms and $^{96}$Ru atoms and one of the isobars, $^{96}$Zr beam will be provided by the laser ion source (LIS).
To provide $^{96}$Zr beam from laser ion source, we are investigating the characteristics of oxide of enriched $^{96}$Zr powder. The reason for using oxides as a laser target is that $^{96}$Zr occupies only about 2 - 3 % in the natural abundance of Zr. Therefore, solid metal of $^{96}$Zr is very expensive and oxide materials, which may be easily obtained in the market, are being tested. We believe this study is useful for applying the rare materials in other ion sources including ECR.
As a method of forming an oxide laser target, sintering is being tested. The compressed oxide powder is heated for several hours at a high temperature more than 1000 °C. In the laser plasma from the oxide target, many impurities are expected. For this reason, atoms for each mass-to-charge ratio are investigated using EIA (Electrostatic Ion Analyzer), and performance of the oxide targets are evaluated. We will present the latest experimental results.
