Forward calorimeters, located near the incident beams, complete nearly 4π coverage for high pT particles resulting from proton-proton collisions in ATLAS detector at Large Hadron Collider CERN. Both technology and deployment of forward calorimeters are novel. The liquid argon rod/tube electrode structure was invented specifically applications rate environments. placement adjacent to other relatively close interaction point provides several advantages including seamless calorimetry natural...

The signals received from the optical receivers like as SiPM and PMT due to collision of energetic particles with scintillators attached these receivers, are weak fast. To measure number well their peak height electronic circuits, it is necessary optimize signals. An example driver circuit, signal counting measurement presented in this text. Also, circuits signals, including amplification, elimination background noise, conversion digital increase duration At end, two examples test results...

SiPMs operate in Geiger mode, wherein photodiode cells are reverse-biased to the breakdown by even a single photon. Each cell is connected series with quenching resistor, which prevents damage and resets after making signal. All arranged parallel, biasing circuits vulnerable over-illumination, where current passing through SiPM can exceed allowable value, leading damage. In this study, we investigate over-current conditions propose protective method against over-illumination using resistor....

Forward proton spectrometers at high-energy colliders rely on precision timing to discriminate signal from background. Silicon low gain avalanche diodes (LGADs) are a candidate for future detectors in these systems. A major challenge the use of LGADs is that must be placed within few mm beams, resulting very large and highly non-uniform radiation environment. We present first measurement current capacitance vs. voltage behavior LGAD sensors, after irradiation with beams 24 GeV/c protons...
