LHC and Injectors failure statistics for Run 2 M. Vekaria, A. Apollonio, T. Cartier-Michaud 6/06/2019

Introduction • • Data sources Introduction to LHC Operations • Fault statistics in BModes Injection Investigation • Physics and Probe Avail. Sim inputs 12/15/2021 3

Availsim • Monte-Carlo simulation tool • • Inputs based on observed performance • • • Simulate the operation of accelerators eg. LHC Works using different reliability measures (Mean Time To Repair, Mean Time To Fail) from faults These change depending on the beam mode they occur in. Also requires Beam Mode durations as an input 12/15/2021 5
