Description
Electron-positron pair production and hadron photoproduction are the most critical beam-induced backgrounds at linear electron-positron colliders. Predicting them accurately governs the design and optimization of detectors at these machines and, ultimately, their physics reach. With the proposal, adoption, and first specification of the C$^3$ collider concept, it is of primary importance to estimate these backgrounds and begin the process of tuning existing linear collider detector designs to fully exploit the parameters of the machine. A report on the status of estimating both of these backgrounds at C$^3$ using the SiD detector concept is presented with a discussion on the effects of machine parameters on preliminary detector and electronics design.
