Title: RD53A: A large-scale prototype chip for the phase II upgrade in the serially powered HL-LHC pixel detectors

Abstract

The phase II upgrade of the HL-LHC experiments within the LHC intends to deepen the studies of the Higgs boson and to allow the discovery of further particles by adding an integrated luminosity of about 4000 fb^-1 over 10 years of operation. This upgrade would overwhelm the installed pixel detector readout chips with higher hit rates and radiation levels than ever before. To match these extreme requirements the RD53 collaboration, a joint effort between ATLAS and CMS, developed RD53A, a new generation pixel detector readout chip prototype manufactured in a 65 nm CMOS technology. It is half the size of the final pixel chips and designed to meet requirements in the face of 3 GHz/cm² hit rate after irradiation to 500 Mrad. The detector is able to use 50×50 μm² or 25×100 μm² pixels with high readout speed of up to 4 links per chip with 1.28 Gbit/s each. Shunt–LDO regulators integrated on the bottom of the chip provide the required voltages to the two power domains, analog and digital. These regulators enable serial powering of the pixel modules, which is the only feasible, radiation hard scheme to ensure acceptable power cable losses and to stay within the material budgetmore »« less

Evaluation of planar silicon pixel sensors with the RD53A readout chip for the Phase-2 Upgrade of the CMS Inner Tracker

Journal Article Adam, W. ; Bergauer, T. ; Damanakis, K. ; ... - Journal of Instrumentation

The Large Hadron Collider at CERN will undergo an upgrade in order to increase its luminosity to 7.5 × 10³⁴ cm^-2s^-1. The increased luminosity during this High-Luminosity running phase, starting around 2029, means a higher rate of proton-proton interactions, hence a larger ionizing dose and particle fluence for the detectors. The current tracking system of the CMS experiment will be fully replaced in order to cope with the new operating conditions. Prototype planar pixel sensors for the CMS Inner Tracker with square 50 μm × 50 μm and rectangular 100 μm × 25 μm pixels read out by the RD53A chip were characterized in the lab and at the DESY-IImore »« less

Test results and prospects for RD53A, a large scale 65 nm CMOS chip for pixel readout at the HL-LHC

Journal Article Gaioni, Luigi - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

The CERN RD53 collaboration was founded to tackle the extraordinary challenges associated with the design of pixel readout chips for the innermost layers of particle trackers at future high energy physics experiments. Around 20 institutions are involved in the collaboration, which has the support of both ATLAS and CMS experiments. The goals of the collaboration include the comprehensive understanding of radiation effects in the 65 nm technology, the development of tools and methodology to efficiently design large complex mixed signal chips and, ultimately, the development of a full size readout chip featuring a 400 × 400 pixel array with 50μm pitch.

Evaluation of HPK $n^+$$-$$p$ planar pixel sensors for the CMS Phase-2 upgrade

Journal Article Adam, W. ; et al. - Nucl.Instrum.Meth.A

To cope with the challenging environment of the planned high luminosity upgrade of the Large Hadron Collider (HL-LHC), sched-uled to start operation in 2029, CMS will replace its entire tracking system. The requirements for the tracker are largely determinedby the long operation time of 10 years with an instantaneous peak luminosity of up to 7.5 × 1034 cm−2 s−1 in the ultimate perfor-mance scenario. Depending on the radial distance from the interaction point, the silicon sensors will receive a particle fluencecorresponding to a non-ionizing energy loss of up to Φeq = 3.5 × 1016 cm−2.

Comparative evaluation of analogue front-end designs for the CMS Inner Tracker at the High Luminosity LHC

Journal Article Adam, W. ; Bergauer, T. ; Blöch, D. ; ... - Journal of Instrumentation

The CMS Inner Tracker, made of silicon pixel modules, will be entirely replaced prior to the start of the High Luminosity LHC period. One of the crucial components of the new Inner Tracker system is the readout chip, being developed by the RD53 Collaboration, and in particular its analogue front-end, which receives the signal from the sensor and digitizes it. Three different analogue front-ends (Synchronous, Linear, and Differential) were designed and implemented in the RD53A demonstrator chip. A dedicated evaluation program was carried out to select the most suitable design to build a radiation tolerant pixel detector able to sustainmore »« less

In-Pixel Readout IC with compact in-pixel ADC for Pixel detectors at HL LHC

Conference Parpillon, Benjamin

The prototype Smart Pixel concept test chip (SP28), designed in a CMOS 28 nm bulk process, is a proof of concept readout integrated circuit (ROIC) designed for a future Phase III High Luminosity upgrade of the Large Hadron Collider. It employs a synchronous analog to digital converter (ADC) for the front-end design, with signal processing and data conversion within a single bunch crossing of 25 ns. It is therefore capable of accurately detecting hits occurring in consecutive bunch crossings, without off-time registration of events and pileup insensitivity, making it particularly suitable for the inner most layers of the vertex detector.more »« less
