<center>Nu_06: *ND280-Upgrade and the neutrino cross section measurements in !T2K* </center>

_Summary_: <br>
The Nu_06 team is foreseen to continue its activity on three main topics:<br>
 - The hardware upgrade of the !T2K off-axis near detector (ND280-Upgrade).<br>
 - Preparation of the analysis of the !T2K data with the ND280 Upgrade detector.<br>
 - Measurements of neutrino-nucleus cross sections using data available from INGRID, !ND280
and WAGASCI/Baby-MIND detectors.<br>
The common goal of these three activities is to reduce the systematics related to the neutrino-nucleus interaction in order to maximize the sensitivity of !T2K. It will also benefit future long baseline neutrino experiments such as Hyper-Kamiokande.

<center>Nu_08: *The Development of the electronics and its synchronization for Hyper-Kamiokande* </center>

_Summary_: <br>
The Hyper-Kamiokande detector will be the largest underground water Cherenkov detector ever built with a 68 m diameter and 72 m height cylindrical tank, equipped with up to more than 50,000 photo-sensors. Timing synchronization of each PMT signal is crucial for a precise reconstruction of the particle tracks due to the triggerless nature of the detector. Moreover, the association between the local time base and the Coordinated Universal Time (UTC) is fundamental to synchronize the data acquisition with the beam sent from the J-PARC particles accelerator in Tokai and to correlate the astronomical events with other detectors. 

!IN2P3 and University of Tokyo have established a strong collaboration and are co-responsible for both these tasks. To achieve them, an R&D campaign is started with the goal of building a high-speed serial link with embedded clock based on the Field Programmable Gate Arrays (FPGA) serializer-deserializer. The final architecture foreseen a signal that originates from an atomic clock to guarantee a very stable and precise cadence (in the order of 1 ps) associated to a Global Navigation Satellite System (GNSS) receiver to get an UTC reference. It is then distributed, embedded into a data stream, from a master entity  to all the front-end nodes. Each front-end extracts the clock with a deterministic phase shift and a less then 100 ps RMS jitter. The data stream is used to exchange critical slow control information between the front-ends and the data acquisition system.
