The NFS facility
Timeline 19 th Dec 2014 : First proton beam delivered by the source 3 th Dec 2015 : First beam accelerated through the RFQ 9 th of June 2016 : NFS experiments @ GANIL PAC end of 2016 : End of the installation of NFS Final authorization (deuteron beam + LINAG) expected by beginning 2017 Deuterons beam in the RFQ : beginning of 2017 LINAC commissioning : T2-T3 of 2017 NFS commissioning : as soon as the LINAG s beam is available First experiment : end of 2017
First experiments 10 experiences submitted to the PAC of 9 th and 10 th of June 2016 -> 7 accepted For the first call : o no deuterons beam o no burst selector limitation on realizable experiments NUM Titre Spokesperson Reaction model E712 Measurement of (n,xn) reaction cross sections on U238 G.

NFS in CHANDA WP 4 : Transnational access Task 7.4: The Transparent Neutron Beam Monitors for NFS and n_tof EAR2 Monitor based on fission Micro-megas Task 7.5: Commissioning of the NFS facility (Task coordinator: GANIL) Beam flux and spectra measurement Back-ground evaluation Post-doctoral position Not before sep 2017 Task 7.6: Container for the transport of actinide samples. (See next slide) Needed for transport of actinides samples to the experimental area Acquisition or development of a container
NFS CHANDA 90 k was funded for the container for actinide sample transportation (WP 7.6) Evolution of the project : A much less expensive solution has been fund for the container The construction of the converter is more expensive than expected, especially due to additional safety constrains A new repartition of the budget was proposed : - Container for the transport of actinide 8 k - Development of the converter for neutron production 50 k - Development of neutron beam dump 12 k - Neutron flux measurement set-up (detector and electronic) 20 k
Extractor Lithium converter monitor
Summary WP 7.5 : commissioning of NFS before nov 2017 : very difficult WP 7.6 : o Container for the transport of actinide under design 8000 o Lithium Converter installed 19975 o Extractor for convertor delivered 26395 o Neutron beam dump under construction 12000 o Neutron monitor Electronic for scintillator delivered 4000 Proton spectrometer under study
