1. Technical news:
· The first MINIBALL experiment for this year was a success. Coulomb excitation was performed on 188,190Pb. The original scientific goals were accomplished and bonus data was collected for 194, 196, 198Pb.
· Currently ISOLTRAP is using beam from HRS in order to work with Pb and Tl. There are issues with sparking in ISCOOL.
· A user broke into the laser cabin and damaged the interlock system blocking the entrance door. Users have to be more careful in the future and follow the instructions on the warning signs.
· Problems with the vacuum control system of REX have been solved. Currently REX runs at a lower efficiency for heavy beams due to poor vacuum in the RFQ.
· Radiation alarms corresponding to activity of above 6mSv/h have been triggered first at HRS during the weekend and then at GPS on Wednesday. Measures have been taken by the RP.
· A refurbished used target has been installed at GPS for the upcoming experiments on COLLAPS, ISOLTRAP and SSP. The target has recovered from four power drops so far.
2.A.O.B.
· ISOLDE was well represented at the ARIS conference with 13 oral presentations of ISOLDE results (most of any facility) and a large attendance of the technical team.
· Nobuaki Imai from KEK (Japan) joins the ISOLDE team for the next two years. He will work on development on refractory elements, first extracted as neutral molecules, broken-up in a second step in the ion source, and further selectively ionized by RILIS.
· Laurianne Fouché from the course of Elias Khan at the University of Orsay joins ISOLTRAP as a summer student.
3. Seminars:
· Klaus Blaum (Max-Planck-Institut für Kernphysik - Heidelberg) presented“Precision Penning Trap Experiments with Stored and Cooled Exotic Ions”.
· Next week Burcu Cakirli (also from MPI-K-Heidelberg) will speak about improvement to ISOLTRAP through position measurements of the ejected ions.
· For more information and links to the slides please visit the ISOLDE - seminars page.
