ESS Vacuum System Standardization Meeting Overview
The ESS Vacuum System Standardization Meeting held in Lund, Sweden, focused on standardizing vacuum equipment and requirements for accelerator, target, and neutron scattering instruments. The scope of activities of the ESS vacuum team, vacuum requirements, integrated approach, and available facilities were discussed to ensure compatible vacuum designs and efficient operation. Collaboration with partners and establishing a Vacuum Equipment Standardization Task Force were key highlights to promote common vacuum equipment usage.

Kick-off Meeting Vacuum Equipment Standardization Welcome Introduction to the Vacuum Equipment Standardization Program Scope Vacuum Requirements An Integrated Approach Available ESS Vacuum Facilities Vacuum Equipment Considered for Standardization Implementation Strategy
Scope of ESS Vacuum Team Activities The ESS vacuum team has overall responsibility for all technical vacuum systems used on the: Accelerator, Target and Neutron Scattering Instruments and Neutron Guides Providing guidance and on going support to ensure the implementation of compatible vacuum designs for e.g. vacuum chambers, components and other equipment exposed to a technical vacuum environment and supporting these systems during commissioning and operations.
Vacuum Requirements Vacuum requirements are dictated by physics and individual system requirements. Accelerator Required vacuum levels for the various areas of the accelerator are summarized in ESS Requirements together with the gas flow rate and gas species required for the Ion Source. Typically vacuum levels, except for the front end, will be in the 10-8 mbar range or better. Target The requirements for target systems are not currently defined. Neutron Scattering Instruments and Neutron Guides Vacuum levels required for the various Neutron Scattering Instruments will vary depending on the science to be performed. Vacuum levels will typically range from the 10-2 to 10-6 mbar. Neutron guides will operate in the 10-3 10-4 range.
An Integrated Approach Working closely with our partners across the project one of our primary goals will be to promote the use of common vacuum equipment. To meet this goal a Vacuum Equipment Standardization Task Force will be established, a major objective for this meeting. The Equipment Standardization Task Force will comprise representatives from the various ESS partners involved in the use of vacuum equipment on the various accelerator subsystems, i.e. ion source, DTL s etc. The mandate of the Task Force will be to develop a list of standard vacuum equipment to be used project wide to minimize project costs, reduce spares holdings, training and achieve other benefits from standardization.
Available ESS Vacuum Facilities Vacuum facilities will be provided to support both construction (installation) and pre operational activities at ESS, including: outgassing test chamber for material and component investigations, general purposes bake out and drying ovens for preparation of equipment prior to installation, support equipment including pump carts, leak detectors etc., ISO Standard 209 Class 4/5 (Fed Standard 209D Class 10/ 100) cleaning and washing area for preparation of warm sections and other critical components prior for installation, pump carts, leak detectors, portable cleanrooms and other equipment dedicated to clean cryomodule beam line connections, provision of limited spares to support vacuum operations through the pre operational phase, provision of pump carts, leak detectors, cold traps and other equipment to support maintenance of activated and/or contaminated equipment.
Vacuum Equipment considered for Standardization A preliminary list of equipment to be included in this Standardization Program could include: Primary pumps; Ion, turbomolecular, getter etc. and pump controllers Secondary pumps; scroll or other dry pumps, Valves; gate valves, angled valves both metal and elastomer sealed, Gauges and gauge controllers RGA s, leak detectors, etc. In general these will supplied by the ESS to support work at ESS. The supply of specific equipment required by ESS partners to support work at their facilities will be their responsibility.
Implementation Strategy Set up membership of Standardization Task Force. Identify list of equipment to be standardized. Prepare procurement specifications for standardized equipment. Develop delivery requirements for equipment including spares. Solicit bids and select preferred vendors. Procurement options: vacuum equipment supporting particular subsystem will be provided as an in kind contribution, all major vacuum equipment will be procured by ESS and drop shipped as needed at partner facilities, ESS enters into procurement contacts with the selected vendors and ESS partners order directly from that vendor.
