    The ABC130 barrel module prototyping programme for the ATLAS strip tracker

    Full text link
    For the Phase-II Upgrade of the ATLAS Detector, its Inner Detector, consisting of silicon pixel, silicon strip and transition radiation sub-detectors, will be replaced with an all new 100 % silicon tracker, composed of a pixel tracker at inner radii and a strip tracker at outer radii. The future ATLAS strip tracker will include 11,000 silicon sensor modules in the central region (barrel) and 7,000 modules in the forward region (end-caps), which are foreseen to be constructed over a period of 3.5 years. The construction of each module consists of a series of assembly and quality control steps, which were engineered to be identical for all production sites. In order to develop the tooling and procedures for assembly and testing of these modules, two series of major prototyping programs were conducted: an early program using readout chips designed using a 250 nm fabrication process (ABCN-25) and a subsequent program using a follow-up chip set made using 130 nm processing (ABC130 and HCC130 chips). This second generation of readout chips was used for an extensive prototyping program that produced around 100 barrel-type modules and contributed significantly to the development of the final module layout. This paper gives an overview of the components used in ABC130 barrel modules, their assembly procedure and findings resulting from their tests.Comment: 82 pages, 66 figure

    Verification of simulated ASIC functionality and radiation tolerance for the HL-LHC ATLAS ITk Strip Detector

    No full text
    ASICs are important components in many HEP detectors and their functional simulation ensures successful operation while minimizing the number of long production cycles. Three radiation-tolerant ASICs (HCC, AMAC, and ABC) will perform the front-end readout, monitoring, and control of the outer layers of the ITk Strip particle tracker for the HL-LHC ATLAS detector. Simulated verification with the Python-based cocotb framework allows for sophisticated tests with major contributions from students and firmware non-experts. The verification program includes interactions between multiple ASICs, realistic HL-LHC data flows, operational stress tests, and a focus on mitigation of disruptive Single Event Effects due to radiation

    Testing of the HCC and AMAC functionality and radiation tolerance for the HL-LHC ATLAS ITk Strip Detector

    The ITk Strip is a new silicon-strip charged-particle detector for the HL-LHC ATLAS experiment. The HCC and AMAC chip are radiation-tolerant ASICs that contribute to the front-end readout, monitoring and control of the ITk Strip. Comprehensive functionality tests have been performed on HCC and AMAC to guarantee their reliability throughout the HL-LHC lifetime. In addition, to ensure the operation of the HCC and AMAC under a radiation heavy environment, gamma, heavy ions, proton and x-ray irradiation campaigns were conducted. HCC and AMAC successfully operated at extreme conditions and were reliable at the expected HL-LHC conditions

    The high-luminosity LHC requires a complete overhaul of the ATLAS inner tracker subsystem, including a new silicon-strip charged-particle tracking detector. The HCCStar (Hybrid Controller Chip) is one of three new radiation-tolerant ASICs for this subsystem. As the interface to multiple binary readout ASICs for the strip detector, the HCCStar buffers and forwards controls signals and trigger and readout requests to them, and serializes their output at 640 MHz. All HCCStars undergo a suite of tests to verify their analog and digital functionality, and large statistics of performance with various operational parameters are collected

    Real time tracker based upon local hit correlation circuit for silicon strip sensors

    No full text
    For the planned high luminosity upgrade of the Large Hadron Collider (LHC), a significant performance improvement of the detectors is required, including new tracker and trigger systems that makes use of charged track information early on. In this note we explore the principle of real time track reconstruction integrated in the readout electronics. A prototype was built using the silicon strip sensor for the ATLAS phase-II upgrade. The real time tracker is not the baseline for ATLAS but is nevertheless of interest, as the upgraded trigger design has not yet been finalized. For this, a new readout scheme in parallel with conventional readout, called the Fast Cluster Finder (FCF), was included in the latest prototype of the ATLAS strip detector readout chip (ABC130). The FCF is capable of finding hits within 6 ns and transmitting the found hit information synchronously every 25 ns. Using the FCF together with external correlation logic makes it possible to look for pairs of hits consistent with tracks from the interaction point above a transverse momentum threshold. A correlator logic finds correlations between two closely spaced parallel sensors, a “doublet”, and can generate information used as input to a lowest level trigger decision. Such a correlator logic was developed as part of a demonstrator and was successfully tested in an electron beam. The results of this test beam experiment proved the concept of the real time track vector processor with FCF

    Irradiation testing of ASICs for the ATLAS HL-LHC upgrade

    For the high-luminosity upgrade to the LHC, the ATLAS Inner Detector will be replaced by an all-silicon tracker (ITk) consisting of two systems: pixels and strips. HCC and AMAC are ITk Strip ASICs vital for performing the system readout, monitoring, and control. To ensure these ASICs will successfully operate in the high-radiation environment of the HL-LHC, they need to be tested for radiation tolerance, and tests have been performed using both heavy ions and protons. The ASIC designs were shown to protect against radiation related effects

    For the Phase-II Upgrade of the ATLAS Detector [1], its Inner Detector, consisting of silicon pixel, silicon strip and transition radiation sub-detectors, will be replaced with an all new 100% silicon tracker, composed of a pixel tracker at inner radii and a strip tracker at outer radii. The future ATLAS strip tracker will include 11,000 silicon sensor modules in the central region (barrel) and 7,000 modules in the forward region (end-caps), which are foreseen to be constructed over a period of 3.5 years.

In order to develop the tooling and procedures for assembly and testing of these modules, two series of major prototyping programs were conducted: an early program using readout chips designed using a 250 nm fabrication process (ABCN-250) [2,2] and a subsequent program using a follow-up chip set made using 130 nm processing (ABC130 and HCC130 chips). This second generation of readout chips was used for an extensive prototyping program that produced around 100 barrel-type modules and contributed significantly to the development of the final module layout.
