Update 05.18.2018 -- Run 9 embedding: Jet Reconstruction Efficiency (R = 0.3, Charged)

We need to know the jet reconstruction efficiency to correct the unfolded measured spectrum, so this is a quick study of the reconstruction efficiency for R = 0.3 charged jets.  There are essenti

Effect of ending the gap cleaning on the star backgrounds in 27GeV

Around 5pm on 5/17/18 Angelica turned off the gap cleaning to see the effect this had on the STAR backgrounds.

TPC Field Cage Currents in AuAu27 for Runs 18 and 11

 First, I show what appears to be a clear correlation between the TPC field cage currents on day 134 (May 14th) and Jeff's metric of the "big" events that we understand to be associated

Update 05.16.2018 -- Run 9 pp: EtTrg = 9 - 15 GeV Spectrum

Here are the pTcorr spectra for eTtrg = (9, 15) GeV, R = 0.3, charged recoil jets.  The distributions have been normalized by the no. of triggers, eta acceptance, and bin width.

Update 05.16.2018 -- Run 9 pp: R = 0.3 Binning Definition

I've decided on a binning to stick with for the detector recoil jet 'pTcorr' distributions (the 'R = 0.3', charged recoil jet distributions, that is).  The last couple of bins for each trigger ha

Fill by fill analysis of bunch cleaning for 27GeV

I've looked at the large events across long periods.    

Detailed Analysis of the effect of bunch cleaning for 27GeV events.

Starting in the 27GeV run we started to see abnormal charge steps in the tpc:
