1. Technical news:

· The general progress of technical work at ISOLDE is satisfactory. Some details a listed below.

· The work on the vacuum commissioning of FE7 (GPS) has started. A valve needs to be changed.

· New multi-pin connector for feedback and thermocouple readout from the targets will be tested this week as well as the power supplies for the target stations.

· The clamps of FE6 (HRS) have been changed.

· Two new pick-ups for primary beam diagnostics have been installed in the BTY line.

· The Tesla-meter setups have been rearranged in order to be easier to reset them.

· The beam-diagnostic group is working on the auto-ranging function of the Faraday cups.

· They are also investigating some problems on wire-grids at HRS.

· A motor needs to be replaced in one of the robots in the target area. This will be done by the external contractor.

· The beam instrumentation and vacuum control of REX is to be commissioned in the second part of April.

· A leak has been found at EBIS, currently being fixed.

· The control room has been refurbished and has a new layout.

· There is the intention to improve the exhibit of targets shown to visitors.

2.Safety

· A map of radiation levels has been established by the RP (Alexandre Dorsival).

· Measures will be taken to further reduce the levels in the RILIS cabin.

3. A.O.B:

· Thierry presented Joao Pedro Ramos - a new student working with the target group on a master thesis. He investigated the ISOLDE CaO material and found out that it qualifies as a nano material.

· CERN needs to evaluate the consumption of liquid helium. Magda will collect the estimates for quantities needed for each experiment over the next 2 years.

4. Seminars:

· There will be no seminar next week.

· Yuri Litvinov will speak about TSR on April 20.

· As already announced, Rick Casten will visit ISOLDE and give a series of lectures in the period Apr 27 to May 12.

· For more information, please, visit the ISOLDE seminars page at indico.
