Tässä työssä esitellään Jyväskylän yliopiston kiihdytinlaboratoriossa sijaitsevaan
IGISOL-laitokseen rakennetun moniheijastavan lentoaika-massaerottajan (engl. Multi-
Reflection Time-of-Flight mass separator, MR-ToF-ms) käyttöönottokokeen tulokset.
Massaerottaja koekäytettiin loukuttamalla ja erottamalla toisistaan samaan
ionikimpuun sekoitetut 87Rb ja 85Rb-ionit. Tässä kokeessa laitteella saavutettiin
2.6 · 104 massaerotussuhdeluku 2.6 millisekunnin ajassa. Työssä kokeiltiin myös
ionien massavalikoivaa lähetystä moniheijastavasta lentoaika-massaerottajasta jännitepulssitettavan
keskuselektrodin avulla onnistuneesti. In this work, the results from the offline characterisation of the JYFL Multi-reflection
time-of-flight mass separator (MR-ToF-ms) constructed at the IGISOL-facility are
presented. The separator was used to trap and separate ion bunches consisting of
87Rb and 85Rb. Mass resolving power of 2.6 · 104 was achieved in 2.6 ms in this test.
During the characterisation, the use mass-selective ion ejection from the MR-ToF-ms
was also tested and found viable.

(Elsevier BV * North-Holland, 2015)211Po ions in the ground and isomeric states were produced via 238U projectile fragmentation at 1000 MeV/u. The 211Po ions were spatially separated in flight from the primary beam and other reaction products by the ... -
The empirical shell gap revisited in light of recent high precision mass spectrometry data
Manea, Vladimir; Mougeot, Maxime; Lunney, David (Springer, 2023)We present an updated view on the phenomenon of mutually enhanced magicity based on the current experimental knowledge of atomic masses, including some recent precision measurements performed with the ISOLTRAP mass ...
