Firmware development for the Scalable Readout System (SRS) with VMM3a — •Patrick Schwäbig, Finn Jaekel, Jochen Kaminski, and Michael Lupberger — Physikalisches Institut, Universität Bonn

The Scalable Readout System which was developed within the RD51 collaboration is a flexible readout system which can be used with various front-end chips and is scalable from a few channels to many thousand channels.

As a future-oriented technology the VMM front-end chip (ASIC) has been chosen as a successor for the so far prevailing APV25 for innovations in gaseous detector development. Originally developed for the New Small Wheel Upgrade of the ATLAS detector the VMM offers features like continuous readout, low electronic noise and neighbor-enabling logic, which are required to fulfill future demands e.g. for use in the NMX instrument at the European Spallation Source (ESS).

The VMM ASIC has been implemented in recent years in the SRS and was tested in various projects. Additional improvements and enhancements are in ongoing development.

The talk will focus on the progression of the firmware of the FPGA responsible for the VMM readout. Improvements of the readout speed and the necessary adaptions to the VMM readout process will be presented.
