Dear All,

 I'm planning to submit the following poster abstract. I posted

in the dropbox file that Gunther sent as well.

Title: Readout electronics for the sPHENIX Time projection chamber

Presenter: Takao Sakaguchi, BNL

Abstract:

The sPHENIX is the upgrade project of the PHENIX detector and is

currently planned to start its engineering run in 2022. This upgrade

project mainly focuses on the detailed measurement of jets and Upsilons.

We have proposed to build a time projection chamber (TPC) as the main

tracker for the sPHENIX, which has a radial coverage of 30 cm to 78cm

with rapidity coverage of |y|<1.1 and full azimuth. The number of readout

channels will be 154K, and the raw data volume is expected to reach as

much as ~880Gbps. In order to fully exploit the data, we developed a

new readout electronics. The front end part is designed using SAMPA

chips developed for ALICE experiment, and the back end part employs

ATLAS FELIX card and high speed PCs. The readout system can be

operated in continuous readout mode at integration rate of ~100KHz.

 In this presentation, we will present the design of the each readout

electronics component as well as the performance obtained from

the prototype front and back end electronics.
