الوصف: Experiments at future hadron colliders like the High-Luminosity LHC or the proposed 100 TeV circular collider FCC-hh will provide a unique opportunity to explore the limits of the Standard Model of the strong and electroweak interactions and to search for physics beyond the Standard Model. Excellent muon identification and trigger capabilities will be crucial to exploit the experiments’ physics potential. To achieve this goal the muon systems of these experiments will use both fast trigger chambers with nanosecond temporal, but poor spatial resolution and slower precision muon chambers with sub-micrometer spatial resolution for stand-alone momentum measurements. In this contribution a trigger system for the FCC-hh detector is introduced which uses thin-gap resistive plate chambers for bunch crossing identification and small diameter cylindrical drift tube chambers for an accurate momentum measurement both at trigger level and offline. Trigger algorithms and their VHDL implementation will be presented as well as the design of a hardware demonstrator employing modern high-performance FPGAs with more than 100 high-speed transceivers.

الوصف: This paper evaluates the development of automated assembly techniques for discrete lattice structures using a multi-axis gantry type CNC machine. These lattices are made of discrete components and are referred to as “digital materials.” We present the development of a specialized end effector that works in conjunction with the CNC machine to assemble these lattices. With this configuration we are able to place voxels at a rate of 1.5 per minute. The scalability of digital material structures due to the incremental modular assembly is one of its key traits and an important metric of interest. We investigate the build times of a 5×5 beam structure on the scale of 1 meter (325 parts), 10 meters (3,250 parts), and 30 meters (9,750 parts). Utilizing the current configuration with a single end effector, performing serial assembly with a globally fixed feed station at the edge of the build volume, the build time increases according to a scaling law of n4, where n is the build scale. Build times can be reduced significantly by integrating feed systems into the gantry itself, resulting in a scaling law of n3. A completely serial assembly process will encounter time limitations as build scale increases. Automated assembly for digital materials can assemble high performance structures from discrete parts, and techniques such as built in feed systems, parallelization, and optimization of the fastening process will yield much higher throughput.

الوصف: The Phase-II Upgrade of the ATLAS Muon Detector requires new electronics for the readout of the MDT drift tubes. The first processing stage, the Amplifier-Shaper-Discriminator (ASD), determines the performance of the readout for crucial parameters like time resolution, gain uniformity, efficiency and noise rejection. An 8-channel ASD chip, using the IBM 130 nm CMOS 8RF-DM technology, has been designed, produced and tested. The area of the chip is 2.2 x 2.9 square mm size. We present results of detailed measurements as well as a comparision with simulation results of the chip behaviour at three different levels of detail.

الوصف: Monitored Drift Tube (MDT) chambers account for the vast majority of precision tracking chambers in the Muon Spectrometer of the ATLAS experiment at the Large Hadron Collider (LHC), where they have to sustain unprecedentedly high background radiation. New, so-called sMDT chambers with reduced tube diameter have been developed for operation at even higher rates, expected after the upgrade of the LHC to high luminosities (HL-LHC). A new ASD chip is required for future upgrades of the MDT chamber front-end electronics and desirable for full exploitation of the rate capability of the sMDT chambers.
