Remarks on the EEMC calibration in 2006
Updated on Sun, 2009-06-07 15:41. Originally created by jwebb on 2009-06-07 13:09.Abstract: We examine pi0 invariant mass spectra from the 2006 run, using isolated pions with no energy deposited in the 1st preshower layer w/in a radius of 0.3. An invariant mass of 139.0 +/- 0.3 MeV is reconstruced, with no observed dependence on pseudorapidity. Conversion rates observed by the preshower layers for identified pi0 decays, indicate that, on average, there are three photons w/in the cluster used to measure the energy of the pion.

TPC Sector 16 time offset
Updated on Tue, 2009-06-02 00:47. Originally created by genevb on 2009-06-02 00:39.I believe I see Tonko's sector 16 time offset in Run 9 physics data (using data from days 147-152). For the 11ns that Tonko sees, one should see 11ns * (5.5 cm/us) ~= 0.06 cm (600 microns).
