Abstract :
The cryomodule tests are on going to have better understandings of physics as a whole and eventually to provide safe and reliable operation for neutron production. Some features are revealed to be interesting issues and need more attentions than expected, such as operating condition, collective effects between cavities, HOM coupler issues, end-group stability, cavity-coupler interactions, and vacuum/gas physics, waiting for more investigations. Up to now SNS cryomodules were mainly tested at 2.1 K/4.4 K, 10 pulse per second (pps) and 30 pps/60 pps tests are under progress. This paper presents briefly the experiences and the observations during tests of cryomodules.
