Objectives of the Proton Improvement Plan Stuart Henderson Fermilab Proton Source Retreat Dec. 7-8, 2010

Objectives Develop a plan, the Proton Improvement Plan (PIP), to meet the goals for Proton Source throughput, while maintaining good availability and acceptable residual activation The plan shall include the required scope, cost, schedule and human resource requirements needed to deliver  the required proton throughput  good availability  acceptable beam loss The plan therefore should address the necessary hardware modifications both for increased repetition rate and improved beam loss, while ensuring viable operation of the proton source through Stuart Henderson, Proton Source Retreat, Dec. 7-8, 20102

Further Elements of the Plan and Planning Process The plan should deliver the proton throughput goals with acceptable risk  In other words, we will not be able to afford to eliminate every vulnerability The plan should identify remaining vulnerabilities at the completion of the plan, and articulate backup plans for those vulnerabilities The plan should identify “hard limits,” beyond which it will become very costly to proceed For example, beamloss and residual activation is one such hard limit. How much improvement in fractional loss can we realistically expect? Stuart Henderson, Proton Source Retreat, Dec. 7-8, 20103

My Thoughts on this Effort If we make a commitment to the physics program, we must deliver on that commitment Conversely, we should not make plans for the experimental program if they’re not supported by plans for delivering the beam Failure to deliver on today’s programmatic commitments jeopardizes tomorrow’s plans This planning process serves very important functions of 1) developing a path to achieve the program goals we have already signed up for, 2) providing a basis for realistic planning going forward Therefore  I view the completion of the PIP, and our execution of it as an urgent, extremely high-priority activity  I have made the completion of the PIP a priority for AD management  I will commit to working at the Directorate level to funding a plan of reasonable scope.

Goal for The Proton Improvement Plan The Proton Improvement Plan, when executed, should enable Linac/Booster operation capable of  delivering 1.8E17 protons/hour (at 12 Hz) by May 1, 2013  delivering 2.25E17 protons/hour (at 15 Hz) by January 1, 2016 while  maintaining Linac/Booster availability > 85%  and maintaining residual activation at acceptable levels and ensuring a useful operating life of the proton source through In addition, the plan should identify remaining vulnerabilities at the completion of the plan, and articulate backup plans for those vulnerabilities identify “hard limits,” beyond which it will become very costly to proceed Stuart Henderson, Proton Source Retreat, Dec. 7-8,
