[Tdis] regular TDIS meeting

Thu Apr 21 18:30:41 EDT 2022

I have not done total rate estimations myself.  A long time ago Marco and Paul looked at total rates.  Their slides are at:

https://hallaweb.jlab.org/wiki/images/7/7f/Pking_tdis_20171114.pdf

Knowing those rates though is important for the tracking in order to know how many tracks per event the tracking algorithms need to deal with.  (Where to look on the X axis of my plot.)  I have assumed 1 GHz total rate in my section of the document.

I have looked at singles rates for the “TDIS” (or do we say VIP) protons.   Knowing these rates is important for calculating accidental rates.  Some of the slides where I discuss this are:

An independent look at these rates is important as I don’t know how good EPC is in the TDIS kinematics.

His are way back in the meeting slides somewhere, but likely he can resend something to compare to. It's a defining number, so good to check.
