On Wednesday the 24.05.2006 the 7th reactor cycle started at the research neutron source Heinz Maier-Leibnitz. More than 70 experiments are planed out of which 22 stem from international collaborations. During the next 52 days measurements will take place 24h a day simultaneously on 14 instruments.

Workshop: Neutrons in Geo Science 14.7.2006


Annual report 2005 is available now


Not even one months after the inauguration of the Jülich Center for Neutron Science JCNS, the first neutron spectrometer arrived on March 15th at the Forschungsneutronenquelle Heinz Maier-Leibnitz (FRM II) in Garching. After the decision of the Forschungszentrums Jülich to shut down their own…

Wednesday, 1.3.06 the reactor was shut down after the regular end of the 5th cycle. The 6th cycle is scheduled for start-up on 24.3.06. The break between the 2 cycles will  be used for routine tests and for installation of new neutron guide systems.

Successful Start of Routine Operation at FRM II

The reactor has been shut down on Sunday, 22.01. 2006 due to a warnig signal in the secondary cooling system, where the cause can not be checked during power operation. This procedure is in accordance with the operating guidelines (BHB) for the FRM-II. The directorate of the research neutron source…

Das Neutronen-Röntgen-Konstrast-Reflektometer N-REX+ wurde am 24.11.2005 eingeweiht. The neutron / X-ray contrast reflectometer N-REX+ was inaugurated on 2005-11-24.

On July,12th the FRM-II was started up, as scheduled, to the nominal power of 20MW. Thus the third power cycle of FRM-II is running. With a short, planned break in early August, the end-of-cycle is scheduled for September 6th 2005.

After successful operation of 48 days the reactor was shut down on 24.6.2005 at 10:46 due to a perturbation on a sensor monitoring the flux of the cooling water. The cooling itself was not disturbed. This shut down ends the second cycle. The remaining 4 days of operation will be used later. The…
