Abstract
<jats:p>We report on the production of ultra-pure samples of the long-lived radioisotope <jats:sup>53</jats:sup>Mn for precision measurements of its half-life. Activated samples from a copper beam dump from PSI, which was irradiated with 590 MeV protons, were used for extraction of the manganese fraction. Following initial radiochemical purification, efficient three-photon laser resonance ionization of manganese inside a hot-cavity laser ion source was applied for subsequent isotope selection in a 30 keV high transmission magnetic mass separator. A new ionization scheme was developed and characterized for <jats:sup>53</jats:sup>Mn implantation. In this way the isobar <jats:sup>53</jats:sup>Cr and the Mn isotopes <jats:sup>54,55</jats:sup>Mn are quantitavely removed, with a special focus on the radioactive <jats:sup>54</jats:sup>Mn isotope. Microgram quantities of <jats:sup>53</jats:sup>Mn were implanted into Al targets with an isotopic and isobaric purity of well above 10<jats:sup>3</jats:sup>. An overall efficiency of the enrichment process of about 15% was demonstrated.</jats:p>
