Hey Brian,
Some questions/random thoughts:
1. Is svtsystem1 on UPS? I assume it is. If it is not on a ups, get a ups. I understand what happened has nothing to do with UPS.
2. How come you don't have admin. privleges? Why didn't you get one? Is it something exclusive like the Centurion card? I want all of you to have admin privileges (Tyler, Peter, Pablo, Amanda, and you). Peter/Brian request Sergey/Nathan for admin. privileges or whoever the privilege giver is.
3. Why is svtsys1 located upstairs? Why not have a computer in the shower curtain room where it would be easily accessible? Thinking of it, take Sahin's computer which is upstairs and put it in the shower curtain room. Go ahead make my day, load red hat, blue hat, or purple hat, i don't care.
I want Peter and you to consider such possibilities and come up with so called emergency contingencies for the RICH detector during the month of December, when everyone is going to be tripping on cranberry sauce and eggnog. We need to think about the Xmas break.
W.R.T. the RICH gas system in the hall and the emergency contingencies, are there any plans other than the electronics will be shut down.
We need to have the emergency contingencies in place by the time the RICH goes to the hall.
Talking of RICH gas system:
Marc please order two liquid dewars starting tomorrow as we are running two dewars in parallel.
i reckon each dewar has 230*700 ~160,000 liters of gas, so 320,000 litres in all.
@ a flow rate of 40 SLM in a week we'd use 40*10,000 =400,000 litres.
Since we have no clue as to when Air Gas graces us with LN2 dewars, as contingency i want you to order 2 LN2 dewars: Mondays and Wednesdays from now till the we know exactly what the flow rate in the RICH is.
