Working field: Remotely operated Laser Ion Source for radio lanthanide purification at medical cyclotrons

- Overall mission: Design and test of new mass separator components to produce new medical isotopes

- Tasks related to new mass separator components and designs:

consideration of Lu, Tb and Er isotopes as primarily requested radionuclides for the MEDICIS project;
for each desired element, it is required to identify a 2- or 3- steps laser ionization scheme;
specific development and refinement of the laser ion source cavity and unit at the JoGU off-line mass separator.

- Tasks within new mass separator components testing:

characterization, testing and spectroscopic application of the JoGU Ti:Sapphire laser system for lanthanides;
optimization of the laser ionization efficiencies under typical conditions for the MEDICIS separator, e.g. at new ISOLDE off-line separator;
achievement of the high selective laser ionization for stable Lutetium isotopes

Post no.

Duration

36 months

Work package

WP1, D1.3: Remotely operated Laser Ion Source for radiolanthanide purification at medical cyclotrons

Recruiting partner

Johannes Gutenberg University Mainz, Germany

Objective

Efficient mono-isobaric ion beam production via elemental selective laser ionization

Expected results

Each chemical element needs a defined 2- or 3-step laser ionization scheme. Terbium, Lutetium and Erbium isotopes will first be considered, using solid-state diode lasers that are better suited for remote operation. The ion source cavity (length, material, temperature) at the mass separator will afterward be developed to increase the ionization efficiencies. Finally a fully automated control software and monitoring will be implemented to foresee its transfer at a medical cyclotron.
