Abstract:
The time of flight energy (TOF-E) setup installed at the scattering chamber of the Q3D magnetic spectrograph to perform heavy ion elastic recoil detection (ERD) analysis at the 14 MV Munich Tandem Accelerator has recently been upgraded. Now, the energy detector of the TOF-E setup is additionally capable of performing $\Delta$E-E measurements for high energy recoil ions obtained from e.g. a 170 MeV \textsuperscript{127}I projectile beam. Time of flight information is simultaneously acquired with the $\Delta$E-E data for each detected ion. The combination of the TOF-E and the $\Delta$E-E data gives the opportunity to set effective filter conditions to select for both, the elemental and the mass of the detected ion. As an example a boron doped carbon layer is analyzed and \textsuperscript{10}B and \textsuperscript{11}B is separated with the help of the combination of both methods. «
