The studies regarding xenon based gaseous mixtures will proceed, with the additives agreed upon with the NEXT Collaboration. The following foreseeable candidate is TEA. We also intend to go to higher pressures (up to 20 atm). Study of the primary scintillation is also planned and has not been done yet due to technical difficulties, so changes in the detector to allow these measurements are under way. When the devices projected are ready, they will be tested and the measurements of drift velocities and gas electrical disruption at high pressure will begin. In the beginning of 2015, a research proposal will be submitted to the FCT PTDC call. This is a proposal presented together with the other two Portuguese teams participating in NEXT collaboration (LIBPhys - University of Coimbra and University of Aveiro). Besides of the local responsibilities of each group, it is predicted that research and technicians will be involved in the assembly, commissioning of the detector and first data acquisition at the Canfranc Laboratory.
