We present the status of the ion source and low energy beam transport prototyping activities for a heavy ion time-of-flight elastic recoil detection analysis (ToF-ERDA) equipment, designed to accelerate a flux of 1–10 particle nano-Ampere of 40Ar6-12+ ions to 3–6 MeV energy for depth profiling of light elements. The prototype injector consists of a novel permanent magnet electron cyclotron resonance ion source CUBE-ECRIS with a minimum-B quadrupole field topology, and a 90° permanent magnet dipole with adjustable field strength for charge state selection. We report experimentally measured argon beam currents as a function of the applied microwave power and ion source potential to demonstrate the feasibility of the CUBE-ECRIS as an injector for a single-ended ToF-ERDA facility with the ion source and low energy beam transport on a 500 kV platform without SF6 electrical insulation. Finally, we present the design and field measurement results of the dipole magnet prototype.

Depth profiling of Al2O3+ TiO2 nanolaminates by means of a time-of-flight energy spectromete
Laitinen, Mikko; Sajavaara, Timo; Rossi, Mikko; Julin, Jaakko; Puurunen, R.L.; Suni, T.; Ishida, T.; Fujita, H.; Arstila, K.; Brijs, B.; Whitlow, Harry (Elsevier, 2011)Atomic layer deposition (ALD) is currently a widespread method to grow conformal thin films with a sub-nm thickness control. By using ALD for nanolaminate oxides, it is possible to fine tune the electrical, optical and ... -
Trajectory bending and energy spreading of charged ions in time-of-flight telescopes used for ion beam analysis
Laitinen, Mikko; Sajavaara, Timo (Elsevier BV, 2014)Carbon foil time pick-up detectors are widely used in pairs in ion beam applications as time-of-flight detectors. These detectors are suitable for a wide energy range and for all ions but at the lowest energies the tandem ...
