First test of a power-pulsed electronics system on a GRPC detector in a 3-Tesla magnetic field

Power-pulsed readout potentially offers a solution to the problem of high power consumption of the electronics for detectors at the future International Linear Collider (ILC) experiments. A 33 × 50cm² Glass Resistive Plate Chamber (GRPC) equipped with a power-pulsed electronics board offering 1cm² lateral segmentation was successfully tested in a 3-Tesla magnet. A significant reduction in power consumption with no deterioration of the detector performance was obtained when the power-pulsing mode was applied. This result shows that highly granular calorimeters for ILC experiments are not only an attractive but also a realistic option.
