Timepix3 hybrid pixel detectors are used in the beam gas ionization profile monitors (BGI) in the primary vacuum of the PS together with a radiation tolerant readout system. Such detectors and readout system could also be used for beam loss and radiation monitoring. The capabilities of the Timepix3 and the readout will be discussed in this talk in the context of beam instrumentation.

A digital (CMOS) radiation tolerant camera is under development through a collaboration between CERN and the Micro-Cameras & Space Exploration commercial partner. The aim is the replacement of already (or very soon) obsolete tube based and CCD analogue cameras that compose the park of 200 profile monitor systems at CERN. Specifications and expected performances of this new camera will be described.

Beam Position Monitoring (BPM) systems are deployed throughout the accelerator complex at CERN. In some cases, their front-end electronics are exposed to high levels of radiation. This presentation focuses on the status and outlook of R2E developments related to BPM front-end electronics, including DAQ and data communication.

In this talk we present the quench detection equipment developed to protect the MBH 11T magnet in the LHC. Since the foreseen UQDS (universal quench detection system) will be installed in RR73 and RR77 the system needs to be radiation tolerant up to 0.4 Gy/y for the main system and 4 Gy/y for the current sensor. The system design, as well as the radiation testing of single components and the...

In the context of consolidation of quench detection systems in LHC, new electronics developments are ongoing to enhance existing system functionalities and improve system operation under radiation. One of the developments, presented in this talk, concerns the quench detection of bus-bar splices in main LHC magnet circuits, with the focus on strengthening the radiation tolerance of the existing systems.

The existing LHC QPS field-bus clients showed vulnerability to the increasing radiation load during Run 2 affecting data integrity of protection data needed for a proper analysis of protection events. To overcome this issue, a new radiation tolerant FPGA-based field-bus client is currently under development. This talk gives an overview of the design solution and the development status.

Distributed I/O Tier (DI/OT) is a modular, reusable and centrally-supported hardware kit based on a 3U crate to cover the needs of the equipment groups in the HL-LHC era. The kit aims to provide basic building blocks and a range of communication options for radiation-exposed areas. The talk will introduce different hardware components that are being designed as well as foreseen applications...

The DI/OT rad-tol System Board is an Igloo2-based CPCI-S FMC carrier that controls the DI/OT crate in radiation-exposed applications. Its specifications, component selection, and development status will be outlined, followed by a brief discussion of the PSI irradiation results of the MoniMod monitoring and fan control module.

Ensuring high reliability for the DI/OT is to be addressed during all life cycle phases within a variety of disciplines. Despite of meeting radiation tolerance requirements, hardware and gateware reliability, operational support, maintenance, and others also contribute to achieving high performance and reliability for the DI/OT. This talk will present the applied methodology and the current progress.

The LHC beam dumping system has critical importance for LHC safety. High Voltage (HV) semiconductors used in extraction and dilution generators operates at up to 28 kV and are potentially exposed to high-energy hadrons leaking from the tunnel. Mitigation measures aiming reduction of the R2E failure rate to the required level are described.

In 2010, and with the objective of improving the LHC availability, CERN decided to replace converters operating under radiation by radiation tolerant ones. This major work focused first on the 600A and kA converters installed mainly in RRs point 1/5/7, all deployed during LS2, after a successful radiation tolerant development and qualification.

We will provide an overview of the ongoing progress and plans to increase radiation tolerance of all MPE-MI equipment impacted by radiation, according to the recent R2E radiation level specification. In particular, we will cover the WIC and PIC systems and the User Interface unit (CIBU) connected to the BIS.
