sPHENIX EMCal discussion

[Joe Osborn <jdosbo AT umich.edu>]

Hi John,

Chris sent a couple of emails out to the software lists, but I guess not the other lists. It might be too late as the BBQ might already be fired up, but for anyone who wants to take a look the G4 hits files are located in the following directory:

/sphenix/data/data02/review_2017-08-02/

Joe,

Thanks to Joe, Jin, and Chris for these results.  There is obviously some bouncy behavior that seems a little odd, but I know that even in very simple cases, getting "the resolution" at the few percent level is not as simple as it sounds.

Just to be clear--this is with the right detector material budget in front of the EMCAL, all events from (0,0,0), and Sean's light collection map in every tower?

Probably as you say nobody's going to have time between the barbecue this weekend and the upcoming barbecues at the lab, but you might ask Chris to post their location to the wiki and the emcal and hcal lists.

Dear EMCalers,

As Jin presented in the simulations/EMCal meeting this week, he has updated the EMCal simulations with the tower tilting in azimuth and polar directions, amongst other changes. With the simulations code tagged, Chris produced single particle simulations that people can play with before we start producing large batches of simulations.

Attached are the resolution of the EMCal for photons, electrons, and positrons in several different eta bins. Just to be clear, the single particles were thrown for 9 different energies in the four different eta regions surrounding the values quoted in my plots (i.e. eta=0 corresponds to truth particles being thrown in +/-0.05 units of pseudorapidity around 0, same for eta=0.3,0.6, and 0.9).

Any comments would be great, or perhaps everyone will be too busy enjoying the long weekend in which case we can also discuss them at the EMCal meeting next week.

Thanks,

Joe
