The NA63 experiment aims to study the radiation process in strong electromagnetic fields. Located at CERN, in the North Area. It is a fixed-target experiment which uses the H4 secondary electron beams from the SPS, which are directed onto different targets. Those are made from a variety of elements, ranging from the relatively light carbon and silicon, through the heavier iron and tin to tungsten, gold and lead and are either amorphous or mono-crystals (made up of diamond for example).
