Working Towards a Photon Cross Section

A schematic view of a cross section is:

BSMD ADC saturation simulation

There's been quite some discussion about the saturation of the BSMD ADCs around 850.  We don't have this feature in the simulator, so here's my attempt to put it in.

Here's a plot of the ADC and energy distributions from the slow simulator in DEV without any reconfiguration.  This is the output of testSimulatorMaker.C using 1000 events from photon MC (photon_25_35_10.geant.root):

Note the sharp ADC peaks at 1023 for the SMDs and the PRS.  Now if I configure the simulator with the options (not yet in CVS)

emcSim->setMaximumAdc(kBarrelSmdEtaStripId, 850.0);
emcSim->setMaximumAdcSpread(kBarrelSmdEtaStripId, 15.0);

emcSim->setMaximumAdc(kBarrelSmdPhiStripId, 850.0);
emcSim->setMaximumAdcSpread(kBarrelSmdPhiStripId, 15.0);


Update

These changes were checked into CVS on October 08 2007

SMD Energy in 2005 pp

Prompted by the recent discussion of the BSMD energy I looked at some histograms for hits from 2005 data. Currently I don't have individual strip energies, I only have SMD clusters saved.

First pass at a photon cross-section with LDA: to-do list

The cross-section requires the following components:

P07ib embedding scheme test

I ran a test set for embedding in P07ib with pi-, ~1.4k events.
