European Spallation Source (ESS) is a multi-MW proton linear accelerator that will be built in Lund, Sweden. Due to the high power of the machine, losses need to be minimized to avoid damaging the accelerator components and quenching superconducting magnets. Loss monitors have to be positioned all across the accelerator, so that they form a reliable protection system. A careful analysis of the loss nature for ESS is in progress to determine the locations for the loss detectors. This paper presents preliminary results of the simulations for the detector response functions, which are calculated for several different energies and incident angles of protons, at certain parts of the accelerator. A simple, baseline geometry configuration is used in the calculations. This paper also gives an overview of the considered ESS beam loss monitoring system. It describes the types of the detectors which are planned to be used at ESS, and discusses the number of detectors needed along different parts of the machine. As planned, a primary tool for measuring losses at ESS will be ionization chambers, the conceptual design of which is given in this paper based on the response time considerations.
