sPHENIX discussion of electronics

[eric mannel <mannel AT bnl.gov>]

Folks-

I would like to submit the following abstract to QM-2019 for a poster. Comments and suggestions are welcome.

sPHENIX is the next stage of the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory designed to provide a detailed understanding of the evolution of the Quark-Gluon Plasma using precision measurements of jets and heavy flavors in heavy ion collisions at RHIC. The sPHENIX detector is based on the former BaBar 1.5T super-conducting solenoid and consists of precision tracking, electromagnetic (EMCal) and hadronic (HCal) calorimetry covering $2\pi$ in azimuth and $\pm1.1$ in pseudo-rapidity. The EMCal is a 2-D projective calorimeter consisting of scintillating fibers embedded in a tungsten powder infused epoxy. The HCal is 2-D projective design using tilted plate consisting of steel absorber and scintillating tiles with wave-shifting fibers. Both the EMCal and HCal calorimeters use a common electronics for readout based on silicon photo-multipliers (SiPMs) as the optical sensor. A custom designed analog front provides amplification and shaping for the 14-Bit ADC system designed for sPHENIX. In this presentation, we will present an overview of the design of the calorimeter electronics, status of the design and prospects for sPHENIX.
