Gaseous detector studies with the VMM3a ASIC and the Scalable Readout System

The VMM3a is an Application Specific Integrated Circuit (ASIC) developed by the Brookhaven National Laboratory (BNL) for the readout of gaseous detectors at high energy collider experiments. Driven by its specifications and the possible use cases in a large variety of applications, the RD51 collaboration has decided to integrate the VMM3a into its Scalable Readout System (SRS). We conducted a series of measurements to demonstrate and commission some of the capabilities of the combination of VMM3a and SRS, which are presented in this paper. The introduction to the system and the experimental set-up is followed by measurements performed to evaluate how the ASIC's capabilities will affect high rate measurements, position reconstruction and spatial resolution, as well as time tagging of correlated events
