J. Alessi Implementation Plan EBIS Project Technical Review 1/28/05 Implementation Plan WBS exists Working on a “bottoms up” cost estimate The following gives some general outline of our plans for the rest of the facility.

J. Alessi Implementation Plan EBIS Project Technical Review 1/28/05 In order to meet the requirements in DOE Order 420.2A, Safety of Accelerator Facilities, C-AD has incorporated a description and safety assessment of the new pre-injector into the current Safety Assessment Document for C-AD. At the appropriate time, C-A Department will obtain an approved Accelerator Safety Envelope for the new pre-injector from DOE and perform an Accelerator Readiness Review in accord with 420.2A prior to commissioning and operations. Safety Assessment Document for C-AD SAFETY The C-A Department conforms to the requirements of ISO 14001, Environmental Management System, and OHSAS 18001, Occupational Safety and Health Management System. Thus, in addition to DOE requirements, documentation of environmental protection and occupational safety and health programs for new pre-injector facilities will be prepared and audited by independent parties. This documentation will include: Environmental Process Evaluations for all processes with significant environmental aspects Facility Risk Assessments for all facilities and areas Job Risk Assessments for all jobs Radiation Safety Committee reviews Accelerator System Safety Review Committee Readiness Reviews Work planning Generation of formal procedures

J. Alessi Implementation Plan EBIS Project Technical Review 1/28/05 Controls: EBIS controls – based on Test EBIS controls. Accelerators & transport lines – standard RHIC-type controls. Cooling systems: Similar to existing units. Power Supplies: Most are standard procurements. Most notable units are: collector ps (15 kV, 15A), pulsed dipole ps’s (12 V, 3000 A ?), and EBIS platform 100 kV isolation transformer/HV pulsing.

J. Alessi Implementation Plan EBIS Project Technical Review 1/28/05 SCHEDULE

J. Alessi Implementation Plan EBIS Project Technical Review 1/28/05 R&D $ requested this year from DOE: Main tasks: Fabricate the collector/extraction and test offline. Measure the temperature distribution on the collector, and optimize the electron beam spreading on the collector surface. Put the present test EBIS on a HV platform. Design and fabricate the LEBT line. Measure output beam emittance vs. trap potentials, ion energy, charge state (confinement time), and ion species, at ~ final EBIS parameters. (In addition, this will then allow this source/LEBT to be used for testing of the final RFQ with beam at least one year sooner than if one were to wait for the RHIC EBIS)

Alessi Implementation Plan EBIS Project Technical Review 1/28/05 Schedule “highlights” (present thinking) Year 1: Procure RFQ Procure/fabricate EBIS solenoid Procure 1 RF ps Fabricate EBIS trap region structure Year 2: Building addition Procure linac and bunchers Procure HEBT dipoles Fabricate LEBT components Test RFQ on Test EBIS Fabricate electron gun, collector, chambers, … Preassembly of EBIS in equipment bay Year 3: Procure collector ps Procure 2 nd RF ps Procure HEBT dipole ps Fab/procure diagnostics Install EBIS-to-Linac in final location Operate EBIS in final location Year 4: Install HEBT Test beam through RFQ, Linac Commission full system

J. Alessi Implementation Plan EBIS Project Technical Review 1/28/05 SUMMARY The Test EBIS has demonstrated that an EBIS meeting RHIC requirements can be built. The RHIC EBIS design incorporates improvements to make it a more reliable device for routine operations. The RFQ and Linac are straightforward, very similar to existing devices. No real issues related to the rest of the beamline or Booster matching. A reasonable design exists for the beamline. We feel that we are ready to begin construction of many components, and can complete design details on remaining components within one year.
