The T2 heat exchanger secondary side solenoid failed on July 9 at approximately 19:30 (EPICS ID: B1A:T2CS:SVSEC).  The valve was replaced with a spare and the cooling package is now running normally.

The valve at this location also failed in November 2016:  https://elog.triumf.ca/TIS/RH-Meson+Hall/211  Further investigation will be attempted to determine if there is a root cause to the failure, or if it is a coincidence.

The attached OneNote PDF contains details of the work.  Cyclotron Fault #10119 has been returned.
