First the good news:
It was possible to make the first chamber bubble. The flow had to be increased passed the 500sccm mark but then
it started to bubble. Will keep it like this and test HV ramping again tomorrow.
While connecting the HV cables to the CTOF, it was found that the light guide of CTOF 2 bottom is broken off. The whole PMT assembly is dangling like a bell.
it needs to be removed and repaired.
