Abstract
A liquid 3He target system was successfully developed for experimental studies of the anti-kaon interaction with a nucleon at the J-PARC hadron facility. Pumped liquid 4He with the temperature of 1.4 K is used to condense gaseous 3He with a total volume of 400 L at atmospheric pressure and 21 °C. A circulation of the liquid between a heat exchanger and a target cell works well for an effective heat transfer between them. The target system was stably operated in the first experiment at the K1.8BR beam line in May 2013.
