Description
The Turkish Accelerator and Radiation Laboratory (TARLA) is a user facility based on a superconducting linear accelerator designed to reach 40 MeV and 1.6 mA. TARLA will be equipped with two beamlines: one for bremsstrahlung and the other for a free-electron laser. Currently, the first accelerating section, providing 20 MeV acceleration, is completed, while the second, for 40 MeV, is under construction. Out of the two beamlines the bremsstrahlung beamline is expected to be available first and start to serve Nuclear resonance fluorescence experiments as soon as available. The current status of the accelerator, project plans, and beam application schedule will be presented. This presentation will detail the accelerator's current status, project plans, and beam application schedule. Furthermore, we will discuss the planned utilization of the operational 20 MeV section for activation and other radiation physics experiments during a pause in the 40 MeV section's construction. By employing a fast sample transfer system measurements of bremsstrahlung and decay properties of nuclei can be made by activation. Thus a set of of activation measurements using 20 MeV bremsstrahlung is planed. These measurements aim at accelerator characterization by establishing the relationship to the generated bremsstrahlung, as well as for measurements of half-lifes of a few short lived nuclei as demonstrator of the sample transfer system capabilities. For accelerator characterization via bremsstrahlung properties activation of Copper (Cu), gold (Au), and tantalum (Ta) will be used, and for studying short lived nuclei Mg-23, S-31, Si-27 and others will be used. After transfer the irradiated samples will be counted using two pairs of CLOVER and single-crystal HPGe detectors with BGO active Compton suppression. The aim of this research was to measure the energy transitions and half-lives of these isotopes as a test of the detector and transfer system capabilities. We will present the status the system and well as of the measurements.
