- Technical News
- There will be a cooling water break on 15th of June.
- Next technical stops of injector chain on weeks 29, 35 and 42.
- EBIS cathode gets poisoned fairly quickly, origin of that not known. For light ions (short charge breeding time), there is a way to go around it by burning and sputtering it clean between cycles, but that may not work for heavier beams.
- Two months LHC shutdown starts on the 6th of December.
- Experiments
- Solid-state physics took beam during weekend. Few hours break on Saturday morning as target heating stopped.
- 2 days technical stop started on Monday morning 5:00, protons back on Tuesday evening 18:00.
- HRS target was changed successfully, although clamps did not connect well which introduced some problems.
- Beam to COLLAPS on Wednesday evening.

· Fire brigade was called into ISOLDE hall due to smell of smoke. Turned out to be just oil tripped on a hot roughing pump and thus a false alarm. It was anyway discussed that if someone is going heat up/bake out anything that may create smell of smoke, a log book entry should be made.
· Two summer students were introduced: Mr. Joonas Konki (MINIBALL, Janne), Mr. Reko Hynönen (COLLAPS, Deyan).
· No group meeting next week due to EURORIB conference.
