12GeV Upgrade - Beam Transport

Injection, Linac, Extraction, & Correctors

Preliminary Design and Safety Review

Outline

• Introduction & Scope• Requirements & Specifications• New/Modified Extraction Elements/Girder Count• Beam Transport Layouts• Safety Considerations• Cost Estimates• Risk Assessment• Summary

Introduction & Scope

• The extraction region must be upgraded to support transport of higher energy beam to halls A, B, & C and 5th pass beam to the new arc 10 to support 12GeV operations

• Songsheet level machine layouts will be presented along with cost estimates

Extraction Region

Requirements & Specifications

• Alignment specs

– Quads & dipoles positioned to +/-0.5mm in x & y, +/- 1.0mm in z

• Vacuum specs

– Beam line partial pressure of hydrogen <10-6 torr

– Total average pressure of all other constituents less than 5x10-7 torr

• Fabrication, welding, cleaning & handling, and leak checking specs still apply

– 22631-S-001 Fabrication of Ultra-High Vacuum Equipment

– 22632-S-001 Cleaning and Handling of U.H.V. Components

– 22633-S-001 Welding Specification For U.H.V. Components

– 22634-S-001 Helium Leak Test For U.H.V. Components

– Note an update and modernization of our vacuum specs is underway

New/Modified Extraction Elements/Girder Count

• Preliminary - pending CASA review and more detailed vacuum study

Safety Considerations

• Personnel Training

– Jlab & sub-contractor

• Radiation

– Designated areas for containment and radiation survey of material that will be removed from the tunnel

• Material handling

– Provide provisions for lifting

• Electrical Hazards

– Package and support electronics, power leads and terminal blocks to control electrical hazards

Risk Assessment

• Technical - Low

– Girders & Supports – very similar designs exist and are already proven

– Vacuum - existing designs already proven, detailed vacuum analysis TBD

– Alignment - same as existing machine

• Procurement Schedule - Low

– No long-lead items identified

• Cost – Low– Good cost estimates for machined parts

• Vendor & Jlab shop budgetary estimates

Summary

• Preliminary extraction beam transport layouts and cost and installation estimates are complete based on present scope

• We are in a good position to support our DOE External Project Reviews this summer

• We will continue to work closely with our friends throughout the lab (safety, CASA, installation, vacuum, alignment, RadCon, I&C, magnet measurement, operations, procurement & facilities) as we move forward

• Detailed design will be completed to support assembly and installation schedules

• We look forward to comments & recommendations from the committee
