EPD Meeting - 8/6/2018

 

Deposited energy of the particles originating from the tunnel entrance

 -In my previous posts, we have seen in vertex plots that several particles are forming a sort of rectangle, which we believe to represent the location of the tunnel entrance. 

Twisting Effect from B Field in STAR

 Due to the magnetic field in STAR, particles' helices will of course bend.

Comparison 2018 TPC Laser Drift Velocities with Old (2013) and New (2018) Alignment based on Cosmics.

Using Cosmic data from days 135 - 162 new TPC sector alignment has been done.
With the new alignment TPC drift velocities have been reproduced for days 66 - 169.

PicoDst Test - 20180802

To have a better understanding on the precision and size impact of the choice of different type of variables for NSigmas, I did a test production with several different setups on a single file.

EPD Calibration: Isobar, Chi^2

 I have now completed going over the Isobar data for EPD calibration purposes (PicoDST data set, non-minbiased).

EPD Calibration: Isobar Data, First Run

 I now have the complete PicoDST data set for the Isobar run. The days I have are: {83-86, 88, 90-129}.
