The NEW detector is a scale 1:2 in size (1:8 in mass) of NEXT-100. The energy plane contains 12 PMTs (20 % of the 60 PMTs deployed in NEXT-100). The tracking plane technology consists of 30 Kapton Dice Boards (KDB) deploying 1800 SiPMs (also 20 % of the sensors). The field cage has a diameter of 50 cm and a length of 60 cm (the dimensions of the NEXT-100 field cage are roughly 1 m long and 1.2 m diameter). An inner, ultra radiopure copper shielding (shown in the picture) is placed inside the vessel in order to protect the active volume from the radioactivity coming from the vessel itself.

It is currently under construction at LSC and will be operational in mid 2016, taking advantage of the same working platform, gas system and external shielding that will be used with the final detector. The platform is seismically insulated in its central part, which will support the detector. The external shield consists of pure lead bricks hosted in a "castle" structure.
