Historic Operations

First 30 years of operations Averaged about 1E19 Protons/Year Users

• Fixed Target • Pbar Production (Starting in 1985)

Booster Duty Cycle was much less than 1 Hz Booster Efficiency was under 70% Major Upgrade - Doubling Linac Energy

• Installation of Klystron System in 1995


Start Neutrino Program and Run II RequirementsFY2000

• Requested Rep rate increased by about a factor of 10• Requested Proton throughput increased by about a factor of 10• Beam quality required significant improvements

MI Slip Stacking Requirements Booster Activation Issues Protons for collider program

• Reduced Scheduled Repair/Study Periods

HEP requests greater than Proton Source could deliver!


Completed Proton Source Upgrades

• Improved Beam Quality New Booster Correctors

• Orbit Control• Corrected Harmonics

Removal of an extraction region• Aperture restriction

Added damping New injection region

• Increased Proton Throughput Added shielding Collimation System

• Controlled loss point• Reduced Component Activation

Improved Low Level control – Cogging/Notching

Conclusion


The domestic accelerator High Energy Physics program for the next 15 years is dependent on the viability and vitality of the Fermilab Linac and Booster.

The Fermilab Associate Director for Accelerators and the Fermilab Accelerator Division Head have established a charge for developing a plan to assure this viability and vitality.

Execution of the plan requires a commitment of significant resources. It is important to move quickly and the support of FRA is essential.

Critical Items in PIP


• Linac RFQ project. This program is now effectively underway, but the project might benefit from a constructive advice from a wider group with a range of relevant experiences. Both a conceptual design review by independent experts and an internal technical design and implementation plan review are appropriate at this stage.

• Booster RF Solid State Program. This and the other Booster RF efforts are presently guided by one individual able to devote an inadequate fraction of his time to each. Undivided attention is required to be prepared for the 2012 shutdown.

• Booster RF Cavities, Tuners, Anode Supplies, and Bias Supplies. Each of these elements cries for, undivided attention for there to be any chance of supporting 12 Hz operation in 2013.

• The entire “Doubling the 8 GeV Beam Flux” category. This range of elements requires one dedicated and informed scientific staff person to serve as a focal point. That person shall provide the oversight and guide the planning of investigations and beam studies necessary to achieve sufficient understanding of the issues. The time scale should be such as to enable proper preparation for effective use of the 2012 shutdown.

• 200 MHz Linac RF Power Systems backup Plans B and C. Especially Plan C to design a “SNS-like” 400 MHz Linac compatible with the present high energy section of the Fermilab Linac should be addressed.

• Linac and Booster Power Distribution Equipment. Items within this category that will be replaced must be prioritized and pre-procurement activities such as specification development and installation planning need to begin in order to effectively procure the equipment in a timely manner when funds become available.

• Booster Spare RF Cavity Program. This effort is in immediate need of skilled mechanical technician labor.
