Wednesday, June 19, 2019, 17:24: Test succesful!

I opened the test stand because I forgot to install tantalum heat shields around the target. Everything was reinstalled as before (with heat shields). I could turn on the TSGTP1B but TSGTP1A does not turn on for some reason. I tried multiple times opening/closing its valve (BV1A) but the pump never starts.

Will keep pumping over the weekend with TP1B only.

 Tuesday, July 02, 2019, 18:24: A blind is installed  on the FEBIAD gas line (see attached picture)  to rule out the possibility of  gases entering the TIS.
