Applications of Bragg Detector for AMS

A Bragg detector was modified systemically for higher sensitivity of accelerator mass spectroscopy (AMS) measurements for medium mass nuclides. The performance of the modified Bragg detector was improved. A series of ³⁶Cl, ⁴¹Ca and ⁷⁹Se standard samples were measured. The results show that this Bragg detector can be successfully used for identification of ³⁶Cl-³⁶S and ⁴¹Ca-⁴¹K. This Bragg detector has a higher charge identification capability than ΔE-E detectors. The nuclear charge identification power was tested and the results show that the Bragg detector can directly determine the value of nuclear charge number within uncertainty of 1.2%.
