TL;DR
This paper introduces the TARGET ASIC, a low-cost, high-speed digitizing and triggering solution designed for the Cherenkov Telescope Array, enabling efficient, scalable camera readout for gamma-ray astronomy.
Contribution
It presents the design and preliminary testing results of the TARGET ASIC, a novel split-ASIC system for fast waveform digitization and triggering in CTA telescopes.
Findings
TARGET C achieves a 1 GSa/s sampling rate with 16k sample buffer.
T5TEA trigger ASIC generates four LVDS outputs based on analog sums.
Preliminary tests show promising performance of the ASICs.
Abstract
The future ground-based gamma-ray observatory Cherenkov Telescope Array (CTA) will feature multiple types of imaging atmospheric Cherenkov telescopes, each with thousands of pixels. To be affordable, camera concepts for these telescopes have to feature low cost per channel and at the same time meet the requirements for CTA in order to achieve the desired scientific goals. We present the concept of the TeV Array Readout Electronics with GSa/s sampling and Event Trigger (TARGET) Application Specific Circuit (ASIC), envisaged to be used in the cameras of various CTA telescopes, e.g. the Gamma-ray Cherenkov Telescope (GCT), a proposed 2-Mirror Small-Sized Telescope, and the Schwarzschild-Couder Telescope (SCT), a proposed Medium-Sized Telescope. In the latest version of this readout concept the sampling and trigger parts are split into dedicated ASICs, TARGET C and T5TEA, both providing 16…
