| Research Abstract |
After finishing construction of the gas filled type magnetic spectrograph (GFM) and installation of the peripheral equipment, we performed an experimental test of the system and tried to make a confirmation of the procedure of the ィイD136ィエD1Cl-AMS measurements.
In order to test whether the special separation between ィイD136ィエD1Cl and ィイD136ィエD1S reaches the design value, we measured the equilibrium charge spectrum using the ion beam with mass of 36 from the accelerator. The analyzing power of the difference of the equilibrium charge states between ィイD136ィエD1Cl and ィイD136ィエD1S was over the design value. This is the result of the choice of the gas and the optimization of the gas pressure.
Using the GFM system, we measure the abundance ratio of the ィイD136ィエD1Cl in the standard samples. We obtained the repeatability of 7% accuracy and the detection limit was set at the ィイD136ィエD1Cl/Cl ratio of 10ィイD1-15ィエD1.
