The DIoGENE instrument (DIffusion GEnerique de NEutrons) has been installed in the IPHI casemate. It features 256 high pressure Helium detector tubes. The electronics (MESYTEC) has been upgraded to operate in event mode.

The RAEVEN setup combining a scintillator and a CCD camera has been setup on IPHI. A first radiograph was measured.
A high power Be target prototype was tested on IPHI (with aluminium mock-ups) at a beam power up to 38kW (90% of the nominal value). The target is divided in 15 sub-elements which can be easily replaced.
The cycle of target testing at 3kW with a power density of 500W/cm² on a Beryllium target was suspended in February. During the previous months, several targets were tested. Some of the targets were operated for about 100 hours corresponding to integrated currents up to 110mA.hours. The proton beamline and the target will be upgraded during spring 2020 to be able to operate at proton beam powers up to 50kW.
A first reflectivity experiment was performed on IPHI.
A first radiography was performed on IPHI
A first diffraction experiment was performed on IPHI
The IPHI - Neutron 7kW set-up has been completed. The first 1kW of power has been sent on the target on April 5th.
A beam profiler has been installed before the target. I allows tuning the optics to optimize the beam spread over the target.

The first proton beam has been sent on the Target Be_V2_7kW.
Shape of the proton beam on the target vizualized with a scintillator for peak currents of 10mA and 60mA. The illuminated area is about 50mm across. The beam power was limited to about 10W to avoid damaging the scintillator.
