Summary and Outlook
Two complementary methods Schottky and Isochronous mass spectrometry
Broad-band simultaneous measurements of ~100 of nuclides High accuracy 5 ∙10-7 for the IMS and up to 4 ∙10-8 for SMS Ultimate sensitivity and efficiency single ion is sufficient Short half-lives down to ~10 s
Ideal for measurements of large-areas of nuclides with very low cross-sections and very short half-lives
Highly-charged ions
Ideal for decay studies relevant for astrophysical scenarios

Summary and Outlook
Two complementary methods Schottky and Isochronous mass spectrometry
Broad-band simultaneous measurements of ~100 of nuclides High accuracy 5 ∙10-7 for the IMS and up to 4 ∙10-8 for SMS Ultimate sensitivity and efficiency single ion is sufficient Short half-lives down to ~10 s
Ideal for measurements of large-areas of nuclides with very low cross-sections and very short half-lives
Highly-charged ions
Ideal for decay studies relevant for astrophysical scenarios

Summary and Outlook
Two complementary methods Schottky and Isochronous mass spectrometry
Broad-band simultaneous measurements of ~100 of nuclides High accuracy 5 ∙10-7 for the IMS and up to 4 ∙10-8 for SMS Ultimate sensitivity and efficiency single ion is sufficient Short half-lives down to ~10 s
Ideal for measurements of large-areas of nuclides with very low cross-sections and very short half-lives
Highly-charged ions
Ideal for decay studies relevant for astrophysical scenarios

Summary and Outlook
Two complementary methods Schottky and Isochronous mass spectrometry
Broad-band simultaneous measurements of ~100 of nuclides High accuracy 5 ∙10-7 for the IMS and up to 4 ∙10-8 for SMS Ultimate sensitivity and efficiency single ion is sufficient Short half-lives down to ~10 s
Ideal for measurements of large-areas of nuclides with very low cross-sections and very short half-lives
Highly-charged ions
Ideal for decay studies relevant for astrophysical scenarios
