	At the European Spallation Source ERIC (ESS), cryogenic cooling is essential for various equipment of the facility. The ESS Superconducting LINAC and the ESS Cryomodule Test Stand, will require major cryogenic services in order to be supplied with liquid nitrogen and helium. Since the use of cryogenic fluids can be associated with Oxygen Depletion Hazard (ODH), the ESS Protection and Safety Systems group will install an ODH Detection System which is a PLC-based alarm system. This system will monitor real time Oxygen concentration levels in designated areas, with the aim to alarm personnel if the oxygen level is detected below certain thresholds. This paper gives an overview about the requirements, system architecture, hardware and software of the ODH Detection System in ESS Accelerator buildings

THCPA02	ESS Accelerator Safety Interlock System	1213

	Providing and assuring safe conditions for personnel is a key parameter required to operate the European Spallation Source (ESS). The main purpose of the Personnel Safety Systems (PSS) at ESS is to protect workers from the facility's ionising prompt radiation hazards, but also identify as well as mitigate against other hazards such as high voltage or oxygen depletion. PSS consist of three systems: the Safety interlock system, the Access control system and the Oxygen deficiency hazard (ODH) detection system. The Safety interlock system ensures the safety functions of the PSS by controlling all hazardous equipment for starting the beam operation and powering the RF-powered units and allowing its operation when personnel is safe. This paper will describe the ESS PSS Accelerator Safety interlock system's scope, strategy, methodology and current status.

THPHA105	ESS Target Safety System Design	1622
	A. Sadeghzadeh, L. Coney, O. Ingemansson, M. Mansouri, M. Olsson ESS, Lund, Sweden
	The purpose of the Target Safety System (TSS) is to protect the public from exposure to unsafe levels of radiation, prevent the release of radioactive material beyond permissible limits, and bring the neutron spallation function into a safe state. In order to fulfill the necessary safety functions, the TSS continually monitors critical parameters within target station systems. If any parameter exceeds an acceptable level, the TSS actuates contactors to cut power to components at the front end of the accelerator and prevent the beam from reaching the target. The TSS is classified as a safety structure, system and component, relevant for the safety of the public and the environment. As such, it requires the highest level of rigor in design and quality for interlock systems at the ESS. Standards are applied to provide a guideline for building the TSS architecture and designing in resistance to single failures and common cause failures. This paper describes the system architecture and design of the TSS, including interfaces with target station and accelerator systems, and explains how the design complies with authority conditions and requirements imposed by development standards.
