1. Technical news:

· The beam lines at both separators are under vacuum.

· HRS has been tested at 60kV. The Boris tube at this separator has been replaced with a new one.

· Some additional insulation has been added to the Boris tube at GPS in order to keep it going for another year. Its high voltage will be tested this week.

· It is planned to have stable beams out of both GPS and HRS by the end of this week.

· There is a new vacuum control system already in place using the PVSS service. G. Vandoni gave an overview of the system on Tuesday (slides). The hands-on demonstration for the users has been rescheduled from Friday to Monday 26-th at 2pm in the ISOLDE control room. For those users who cannot be present there will be a second demonstration at a later date.

· The magnet of REX-EBIS lost its liquid He within a day. It will be warmed up and refilled. If the problem persists the magnet may need to be replaced by a sister unit, which is available in another laboratory.

· The high-voltage platform (next to ISOLTRAP) has been removed. The corresponding beam line will be available for solid-state physics. Part of the space may be occupied by the CRIS experiment.

· The RILIS team tested successfully three recently acquired new dye lasers. These should gradually replace the existing units.

2. A.O.B:

· The ISOLDE weekly schedule is out. For more information including target details etc. follow the link.

· Friday 30-th at 3pm in the ISOLDE visitor’s room, physics coffee with K. Flanagan, who will share some ideas about rare-isotopes production.

· The lectures of Prof. R. Castenhave become a tradition at ISOLDE. He will be visiting again in May and June. If you are interested in a particular topic to be discussed in the lectures, contact M. Kowalska.

· Please, note the list of upcoming ISOLDE seminars.
