Effects of high-energy particle showers on the embedded front-end electronics of an electromagnetic calorimeter for a future lepton collider

Understand

Application Specific Integrated Circuits, ASICs, similar to those envisaged for the readout electronics of the central calorimeters of detectors for a future lepton collider have been exposed to high-energy electromagnetic showers.

• A salient feature of these calorimeters is that the readout electronics will be embedded into the calorimeter layers.
• In this article it is shown that interactions of shower particles in the volume of the readout electronics do not alter the noise pattern of the ASICs.
• No signal at or above the MIP level has been observed during the exposure.
