AbstractAbstract
[en] A liquid argon TPC is a very useful detector for the next generation physics to search for “CP violation in lepton sector”, “nucleon decay” and “dark matter”. The hundred kton liquid argon TPC in the Okinoshima island has been proposed to perform such physics in future. To check the detector performance of liquid argon TPC, especially particle IDs, we performed test beam in October 2010 using K1.1BR beamline in J-PARC hadron hall, so called T32 test-experiment. In last T32 experiment, the prototype cryostat with size of 250 L was borrowed from MEG (Mu → E+gamma) experiment, but we had to bring it back to Europe, therefore we started to design and have produced a new cryostat for the next possible test-beam from September 2010. For the R and D on the liquid argon TPC, the good purity is indispensable, therefore the liquid circulation system and good pre-cooling system is crucial. We added the materials for those R and D improvements to the new cryostat. We report the results of the various performance tests on the cryostat which has been performed at present in this article.

AbstractAbstract
[en] We are developing the high efficiently circulation system for refining liquid argon to high purity for the hundred kton liquid argon TPC. In this measurement, the liquefaction efficiency was measured with the length and the material of the heat exchanger coil. The performance of re-condenser was measured with the test bench and the prototype cryostat with size of 250 L. The efficiency of liquefaction was about 86% with the test bench. With the system of connecting of the re-condenser to the 250LAr container, the flow rate of circulating gas is the maximum 25L/min on -188.5degC of cold head temperature and the maximum 48L/min on -185.7degC. When operating by 48L/min of flow rate of supplied gas, the liquid argon of 300L was able to circulate in about 82 hours. (author)
