  The ATLAS Hadronic Calorimeter DaughterBoard (DB) interfaces the on-detector with the off-detector electronics. The DB features two 4.6 Gbps downlinks and two pairs of 9.6 Gbps uplinks powered by four SFP+ Optical transceivers. The downlinks receive configuration commands and LHC timing to be propagated to the front-end, and the uplinks transmit continuous high-speed readout of digitized PMT samples, detector control system and monitoring data. The design minimizes single points of failure and mitigates radiation damage by means of a double-redundant scheme. To mitigate Single Event Upset rates, Xilinx Soft Error Mitigation and Triple Mode Redundancy are used. Reliability in the high speed links is achieve by adopting Cyclic Redundancy Check in the uplinks and Forward Error Correction in the downlinks. The DB features a dedicated Single Event Latch-up protection circuitry that power-cycles the board in the case of any over-current event avoiding any possible hardware damages. We present a summary of the studies performed to verify the reliability if the performance of the DB revision 6, and the radiation qualification tests of the components used for the design.

  The KOMAC facility consists of low-energy component, including a 50-keV ion source, a low energy beam transport (LEBT), a 3-MeV radio-frequency quadrupole (RFQ), and a 20-MeV drift tube linac (DTL), as well as high-energy components, including seven DTL tanks for the 100-MeV proton beam. The KOMAC has been operating 20-MeV and 100-MeV proton beam lines to provide proton beams for various applications. Approximately 20 stripline beam position monitors (BPMs) have been installed in KOMAC linac and beamlines. A data-acquisition (DAQ) system has been developed with various platforms in order to monitor beam position signals from linac and beamlines. This paper describes the hardware and software system and test results.

  Nowadays technologies in LINAc facilities brought the common Human-Machine Interfaces (HMIs) to be more aligned to the standards coming from the information technology (IT) and the operators started to interact to the apparatus with the common computers’ instruments: mouse and keyboard. This approach has both pro and cons. In order to minimize the cons and with the idea of providing an alternative to interact with HMIs, we tried to design and realize an open-hardware knob system solution.

  The "Cabling and Controls Database" (CCDB) is a central repository where the different teams of ALBA manage the information of installed racks, equipment, cables and connectors, and their connections and technical specifications. ALBA has modernized this web application for sustainability reasons and fit new needs detected throughout the last years of operation in our facility. The application has been linked to Jira to allow tracking problems in specific installed equipment or locations. In addition, it also connects to the ALBA Inventory Pools application, the warehouse management system, where the stock of physical equipment and components are maintained to get information on the life cycle of the different devices. These new features, integrated with proprietary products like Jira and Insight, aim to become ALBA’s asset management system. This paper aims to describe the main features of the recent application upgrade, currently in continuous development.

THPV032 The Demonstrator of the HL-LHC ATLAS Tile Calorimeter electron, detector, high-voltage, hadron 935
 
  • P. Tsotskolauri

  The High Luminosity Large Hadron Collider (HL-LHC) has motivated R&D to upgrade the ATLAS Tile Calorimeter. The new system consists on an optimized analogue design engineered with selected radiation-tolerant COTS and redundancy layers to avoid single points of failure. The design will provide better timing, improved energy resolution, lower noise and less sensitivity to out-of-time pileup. Multiple types of FPGAs, CERN custom rad-hard ASICs (GBTx), and multi-Gbps optical links are used to distribute LHC timing, read out fully digital data of the whole TileCal, transmit timing and calibrated energy per cell to the Trigger system at 40 MHz, and provide triggered data at 1 MHz. To test the upgraded electronics in real ATLAS conditions, a hybrid demonstrator prototype module containing the new calorimeter module electronics, but still compatible with TileCal’s legacy system was tested in ATLAS during 2019-2021. An upgraded version of the demonstrator with finalized HL-LHC electronics is being assembled to be tested in testbeam campaigns at the Super Proton Syncrotron (SPS) at CERN. We present current status and results for the different tests done with the upgraded demonstrator system.

FRAL04 The Control System of the New Small Wheel Electronics for the Atlas Experiment detector, controls, electron, FEL 1005
 
  • P. Tzanis
    NTUA, Athens, Greece
 
  The present ATLAS Small Wheel Muon detector will be replaced with a New Small Wheel(NSW) detector in order to cope up with the future LHC runs of high luminosity. One crucial part of the integration procedure concerns the validation of the electronics for a system with more than 2.1 M electronic channels. The readout chain is based on optical link technology connecting the backend to the front-end electronics via the FELIX, which is a newly developed system that will serve as the next generation readout driver for ATLAS. For the configuration, calibration and monitoring path the various electronics boards are supplied with the GBT-SCA ASIC and its purpose is to distribute control and monitoring signals to the electronics. Due to its complexity, NSW electronics requires the development of a sophisticated Control System. The use of such a system is necessary to allow the electronics to function consistently, safely and as a seamless interface to all sub-detectors and the technical infrastructure of the experiment. The central system handles the transition between the probe’s possible operating states while ensuring continuous monitoring and archiving of the system’s operating parameters.

  MACE Telescope installed in Ladakh Region of India comprises of many functionally diverse subsystems, Camera being the most important one. Mounted at the focal plane of 21 m diameter parabolic reflector dish, event driven Camera system comprises of 1088 PMTs, with 16 PMTs constituting one Camera Integrated Module (CIM). Central Camera Controller (CCC), located in Camera housing, manages and coordinates all the actions of these 68 Modules and other camera subsystems as per the command sequence received from Operator Console. In addition to control and monitoring of subsystems, various mechanisms have been implemented in hardware as well as embedded firmware of CCC and CIM to provide safety of PMTs against exposure to ambient bright light, bright star masking and detection and recovery from loss of event synchronization at runtime. An adequate command response protocol with fault tolerant behavior has also been designed to meet performance requirements. The paper presents the overall architecture and flow of camera control mechanisms with a focus on software and hardware challenges involved. Various experimental performance parameters and results will be presented.
