DESCRIPTION
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, 20103TRANSCRIPT
Objectives of the Proton Improvement Plan

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 2025.

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?

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.

Planned, Proposed and Imagined Experiments
• The situation is complex. We do not (and will not) have all the information. The figure summarizes the planned, proposed and readily imagined requests

Assumptions: • 1.33 sec Main Injector cycle time• 95% Efficiency for 8 to 120 GeV
Note that 44 weeks operation at 80% availability gives 0.67

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 2025.
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
