Hi, Everyone

The INTT digitization fix is updated here:

https://github.com/sPHENIX-Collaboration/macros/pull/134

In this new setting, the threshold is 5.8% of MIP energy which is only slightly higher than the current default of 5%. Meanwhile, the MIP peak should be enclose in the higher ADC range of 4-5, instead of above max ADC as in the current default.

Also thanks a lot to Yorito, who provided INTT test beam data qualitatively confirming this digitization scheme.

Suggest Tony/Christof to have a cross check and merge if we have a consensus.

Cheers

Jin

Subject: Next Meeting of the Inner Tracker Task Force

Hi Everybody,

tomorrow we will have the next meeting of the Inner Tracker Task Force.

The main topics we still need to discuss are:

1) Wrapping up the study of the extrapolation precision from the INTT to the TPC (Ross and Molly)

2) Final plots regrding the pp vertexing (Sookhyun)

3) status of the INTT readout electronics simulation (Jin and Rachid)

The indico page, bluejeans link and google doc can be found here:

See you tomorrow!

Christof
