Good Morning Raith Users and Raith Field Service:
Good flow and pressure were observed this morning after repairs effected
late yesterday to the cooling loop.
The Fe-Gun has returned to normal emission levels after its start up
Users are requested to call me immediately if any cooling or operations
issues are encountered.
Thank you for your support!

I am pleased to report that my efforts to pickle the cooling line loop to the raith appears to have be successful.
After repairs were completed last evening the measured flow rate was 2.5 lpm at ~ 100 psi measured on the output side of the chiller.
This morning inspection measured 3.0 lpm plus and a very nice flow of clean solution is circulating through the loop.
I am going to continue allowing this solution to circulate through the system over the weekend until RAITH Field Service personnel are available to check the system out and flush and refill with normal solutions.
We will monitor flow rate and pressure twice each working day, or if problems are encountered on the tool.
