This overview discusses the development of target systems at SINQ from 2000 to present, featuring advancements in neutron yield and target design. It details the evolution from Target Mark II with lead rods leading to a 42% increase in yield (1997-1999) to the water-cooled Target Mark I (2004-2008) and the hybrid Target Mark III (2006). Additionally, the MEGAwatt Pilot Experiment represents a collaborative international effort aimed at designing and implementing a liquid metal spallation target. The current Target Mark IV combines lead rods with a Zr cladding for enhanced performance.
