Trapping, retention and laser cooling of Th3+ ions in a multisection linear quadrupole trap

A multisection linear quadrupole trap for Th3+ ions is described. Multiply charged ions are obtained by the laser ablation method. The possibility of trapping and retention of ∼103 ions is demonstrated in macroscopic time scales of ∼30 s. Specific features of cooling Th3+ ions on the electron transi...

Description
Summary:A multisection linear quadrupole trap for Th3+ ions is described. Multiply charged ions are obtained by the laser ablation method. The possibility of trapping and retention of ∼103 ions is demonstrated in macroscopic time scales of ∼30 s. Specific features of cooling Th3+ ions on the electron transitions with wavelengths of 1088, 690 and 984 nm in Th3+ ion are discussed; a principal scheme of a setup for laser cooling is presented.
