“…In addition, 50 channels of the detector were fitted with custom-made 10-channel, 38 dB, 650 MHz amplifier cards with built-in discharge protection. The RF amplifier from [8] served as the basis for the design. The signals were digitised and recorded with the oscilloscope.…”

The PICOSEC Micromegas precise timing detector is based on a Cherenkov radiator coupled to a photocathode operating in a semi-transparent mode and a Micromegas amplification structure. The first proof of concept single-channel prototype was able to achieve a time resolution below 25 ps. One of the crucial aspects in the development of precise timing gaseous detectors applicable in high-energy physics experiments is a modular design that enables large area coverage. The first 19-channel multi-pad prototype with an active area of approximately 10 cm2 suffered from degraded timing resolution due to the non-uniformity of the preamplification gap thickness. A new 100 cm2 detector module with 100 channels based on a rigid hybrid ceramic/FR4 Micromegas board for improved drift gap uniformity was developed. Initial measurements with 80 GeV/c muons showed improvements in timing response over the measured pads and a time resolution below 25 ps. More recent measurements with a thinner drift gap detector module and newly developed RF pulse amplifiers show that the pad centre resolution can be enhanced to the level of 17 ps. This work will present the development of the detector from structural simulations, design, and beam test commissioning with a focus on the timing performance of a thinner drift gap detector module in combination with new electronics using an automated timing scan method.

“…Given the superior performance of diamond as a detector material compared with other alternatives, it holds promise for our application. In particle detection, diamond detectors exhibit fast pulses generated by particles, with rising time typically in the range of a few hundred femtoseconds [20]. To process such rapid signals without significant distortion, the design of a TIA with a gigahertz bandwidth is crucial.…”

In this paper, we present a front-end for gigahertz applications, FGATI, which utilizes a transimpedance amplifier design to amplify the current signal from a diamond particle detector. The transimpedance amplifier design adopts a flipped-voltage-follower-based current-mirror (FVF-CM) topology as the input stage, offering advantages such as low power consumption, large transimpedance gain, gigahertz bandwidth, and reasonable noise levels. The FVF-CM topology was realized to improve noise reduction with a fully differential output configuration. The design was implemented as an ASIC chip using 65 nm CMOS silicon technology. The bandwidth measurement of the FGATI prototype demonstrated a 3-dB bandwidth of 1.2 GHz. Furthermore, the amplifier's power consumption is low, drawing only 7.2 mW/channel from a 1.2 V power supply, including the buffer stage. The measurement of the FGATI output signal indicated an excellent transimpedance gain of 79.2 dBΩ and a noise level of 6.7 mVrms. These findings highlight the feasibility and effectiveness of the proposed front-end design in high-frequency applications.
