Matti Leino,Juha Äystö,T. Enqvist,P. Heikkinen,Ari Jokinen,M. Nurmia,A Ostrowski,Wladyslaw Henryk Trzaska,Juha Uusitalo,K. Eskola,P. Armbruster,V. Ninov +11 more
TL;DR: A gas-filled recoil separator for the study of heavy elements has been constructed in this article, which is of type QDQQ with the first, vertically focusing, quadrupole providing improved matching to the acceptance of the dipole magnet.
Journal ArticleDOI
Beam cooler for low-energy radioactive ions
TL;DR: An ion beam cooler for mass-separated radioactive ion beams has been developed and tested at the IGISOL-type mass separator facility as mentioned in this paper, where an energy spread below 1 eV and transmission efficiency of 60% were measured.
Journal ArticleDOI

TL;DR: In this article, a penning trap has been installed for isobaric beam purification at the IGISOL-facility at the University of Jyvaskyla.
Journal ArticleDOI
On-line ion cooling and bunching for collinear laser spectroscopy
A. Nieminen,Paul Campbell,J. Billowes,D. H. Forest,J. A. R. Griffith,Jussi Huikari,Ari Jokinen,Iain Moore,R. Moore,G. Tungate,Juha Äystö +10 more
TL;DR: In collinear laser measurements the signal-to-noise ratio has been improved by a factor of 2 x 10(4), allowing spectroscopic measurements to be made with ion-beam fluxes of approximately 50 ions s(-1).
Journal ArticleDOI
Q values of the 76Ge and 100Mo double-beta decays
Saidur Rahaman,V.-V. Elomaa,Tommi Eronen,Jani Hakala,Ari Jokinen,Juhani Julin,Anu Kankainen,Antti Saastamoinen,Jouni Suhonen,Christine Weber,Juha Äystö +10 more
TL;DR: In this article, the double-beta decay Q-values of 76Ge and 100Mo with uncertainties less than 200 eV were determined using penning trap measurements using mixed beams.
