A new dual injection system for AMS facility
چکیده انگلیسی

In order to measure long-lived radioisotopes such as 10Be with high sensitivity using an HVEE model 4130 AMS system, as well as to guarantee 14C measurements of high precision, a new dual injection system for the AMS system is proposed. The proposal is to add a Wien filter located between the ion source system and the recombinator of the HVEE model 4130. When a pulsing voltage is optionally applied to the Wien filter, a sequential injection mode is turned on. The isotopes would alternately pass on different trajectories through the recombinator. When the pulsing voltage and magnetic field are turned off, the Wien filter acts as a field-free drift space and the standard simultaneous injection mode is on. Beam optics calculation show that the new dual injection system will increase the number of radio-nuclides which can be analyzed, keep the high precision capability for radiocarbon dating and achieve high sensitivity for 10Be and 26Al measurements, together with simplifying the layout as compared to existing dual-injector and dual high-energy beam line systems.
