ATTRACT FASTPIX Monolithic Pixel Sensor Demonstrator for sub-Nanosecond Timing in Future Vertex and Tracking Applications

• Speaker: Justus Braach
• Status: Accepted as talk
• Abstract: Vertex and tracking detectors for future high-energy physics experiments face stringent requirements in view of their spatial and temporal measurement performance as well as the projected experimental conditions. Within the ATTRACT FASTPIX project, a monolithic pixel sensor demonstrator chip has been developed in a modified 180 nm CMOS imaging process technology, targeting sub-nanosecond timing precision for single ionising particles. It features a small collection-electrode design and contains 32 mini-matrices of 68 hexagonal pixels each, with pixel pitches ranging from 8.66 to 20 microns. Various design variations are explored, aiming at an increase in speed and uniformity of charge collection across the pixel area. This contribution explores arising challenges in characterizing the state-of-the-art pixel sensor demonstrator FASTPIX by discussing the preparation, setup and results of beam tests at the CERN SPS. The talk will cover the CLICdp Timepix3-based beam telescope setup, including upgrades for picosecond time measurements as well as performance results from recent test-beam measurements.

Status of the Caribou DAQ System

• Speaker: Eric Buschmann
• Status: Accepted as talk
• Abstract: Developing a new silicon detector requires significant effort for preparing the readout hardware and software for the prototype to be operated in the laboratory and test beams. The Caribou DAQ framework significantly reduces the development effort and cost for such readout systems. By utilizing modern system-on-chip SoC platforms, it combines programmable logic and a processing system and thereby brings unprecedented flexibility to the DAQ design. A universal interface card connects the SoC with the detector prototype, housing power supplies for biasing as well as DACs and ADCs for setting and measuring operational parameters, test pulses, etc. Through this versatile hardware and the modular design, the turnaround time for supporting new detectors is minimized. The system is completed by a set of configurable firmware blocks for commonly used functionality as well as the DAQ software Peary. This talk gives an overview of the Caribou system and presents recent applications and developments, such as the integration of new detector chips: FASTPIX is a monolithic pixel sensor demonstrator chip with sub-nanosecond time resolution implemented in a modified 180 nm CMOS imaging process. The DPTS and APTS are prototype chips using a modified 65 nm process. An oscilloscope based readout implemented in Caribou is used for laboratory and beam tests.
