4. ARSC Assessment Findings – 04/05 4 DateFacilityRecommendations/Suggestions/Observations 02/19/04MSD Accelerator Facility Suggestion: MSD should form an ad hoc committee of experts in electrical safety to review facility electrical safety practices 05/06/04IPNSNone 11/17/04ATLAS FacilityNone 03/23/05Argonne Wakefield Accelerator (HEP) Rec. 01: The division should revise the SAD to make a completely self-contained document. 06/15/052-MeV Van de Graaff (DEP) Rec. 01: DEP should include a staff member from another division during its safety walkthroughs. Rec. 02: DEP should institute a system to document the issues identified during walkthroughs and track them to closure. 11/29/05Low-Energy Accelerator Facility (CHM) Rec. 01: An issue tracking system should be instituted to identify issues and to indicate how they are closed out. Rec. 02: Operator aids, postings, and labels should be updated throughout the facility. Rec. 03: there should be a more formalized electrical safety committee, including a process to identify items of concern. Rec. 04: Should ensure that beam cannot be directed toward adjoining experimental Cell 2 by making it physically impossible.

5. ARSC Assessment Findings – 06/07 5 05/10/06Advanced Photon Source (APS) Rec. 01: APS should review all safety committee charters on an annual basis, and that the charters indicate the person to whom the committee reports, the date of the latest review, and the date on which the committee was formed. Lists of committee members should be kept separate from the committee charter. This will avoid the situation in which a committee is in violation of the charter due to changes in committee members or their organization affiliation. Rec. 02: The APS should review its implementation of lock-out/tag- out to assure that usage conforms to ANL policies and procedures. 12/15/06MSD Accelerator Facility None 03/07/07IPNS Accelerator Facility Observation: IPNS management should consider undertaking a study in the near future regarding the costs of D&D of the accelerator (ion source to PTS beamline) as well as the ramifications of the resulting change in facility status. 11/18/07PHY Division Accelerators Rec. 01: PHY should review and update the charters and membership of all divisional safety committees. Rec. 02: PHY should access their walkthrough inspection process to ensure that significant items are being identified, and institute a system for follow-up to make sure that any issues identified are resolved in a timely manner.

6. ARSC Assessment Findings – 08/09 6 02/14/08HEP Accelerator FacilitiesRec. 01: HEP Division and AWA facility should implement some form of configuration control for the accelerator vault shielding, particularly for the stackable lead shielding used in penetrations between the accelerator vault and the adjacent laser room. The shielding should be visually examined before RF operations and radiation surveys are conducted to verify the shielding performance if the shielding has been moved or altered. 06/13/08MSD Accelerator FacilityRec. 01: Must improve experiment sample safety review process. 07/01/082 MeV Van de Graff (DEP) None 01/22/09Low-Energy Accelerator Facility (CSE) Rec. 01: linac electrical safety issues (CSE put facility on stand-down) Rec. 02: SAD’s out of date. Rec. 03: Designate new CSE division as manager in all documentation Rec. 04: Must formalize operational aids
