Hi Flemming,
I bought up this in one of our ops meetings. From the meeting my understanding was this amount of time is sufficient. But, its better if we talk about this again. Shall we discuss this during the second part of the ops meeting coming Thursday
at 2 pm?
Thanks,
Prashanth

Dear Prashanth,
I think this amount of time for tpc maintenance needs to be discussed
further. What you have is nominal 2 months, but with Thanksgiving and
Christmas it is at least 2 weeks shorter. I suggest we have a meeting
which includes Tonko, Tim, Alexi to discuss a more detailed planning.
There was substantial damage to the electronics from the pp run that has
to be addressed to have a successful Au-Au run
