[dsg-svt] R2B HV Current

[Yuri Gotra]

Thank you Brian,

I am aware of it. Not only S1B but also S3B and S5B (all sensors with 4 
problematic strips) show current increase. These sensors have low bias 
settings already, I keep them such that the leakage is stable and make 
changes when needed. Since yesterday we are running with higher beam 
current and these sensors needed another adjustment which I did. They 
all have higher noise rate and lower efficiency due to sensors being 
under-depleted. But it is better than having the holes.

We also noticed latch up of 4 chips last night:
