	For the first time, in April 2016, the SILHI source produced a proton beam for IPHI RFQ. Due to several technical difficulties on the RFQ water cooling skid, a short RF power pulse (100 μs at the beginning until few hundred microseconds) is injected into the RFQ accelerates the high intensity proton beam up to 3 MeV. The repetition rate is tuned between 1 and 5 Hz. Under these conditions, the beam power after the RFQ is lower than 100 W. At the end of 2017, the 352 MHz RFQ conditioning has been completed (with the same duty cycle) and the proton beam has been accelerated. The increase of the beam power is expected to continue in 2018 in order to reach several kilowatts by the end of the year. In addition, two Ionization beam Profile Monitors (IPM) developed for ESS have been tested on the deviated beam line with a very low duty cycle. The IPHI facility should demonstrate the possibility to produce neutrons with a flexible compact accelerator in the framework of the SONATE project. This paper presents the status of the IPHI project in April 2018.
