ITW primary and secondary vacuum vessel leak check are done. There is a 5XE-8 atm.cc/sec leak on Exit service cap NW side square panel.  The leak is small. And, it is close to ITW TP3 so it is not affect ion beam line vacuum during operation. We will replace the seal on the panel later.   The rest leak check on air to vacuum seals are good. TM2 water lines are pressurized with 70 psi helium. We did it  3 hours after water lines are purged. No leak was showed during the check.

2021-02-24th: The o-ring on exit 1 NW side square panel is replaced by David Wang and Frank Song.
