Prehistory
     The idea of a single-stage 8 GeV injector linac to replace both the Booster and its injector linac was first brought up by Vinod Bharadwaj in a presentation to Fermilab Director John People’s Future Working Group, ca. 1994; and in an abstract submitted to EPAC'94 by Vinod and Bob Noble (then both at FNAL, now both at SLAC).
     At the time of these first proposals, the available technology was based on either the the warm-copper 'Cavity-Coupled-Linac' developed at Los Alamos and used in the 1990 Fermilab Linac Upgrade, or else the Superconducting RF technology as it existed for the Continuous Electron Beam Accelerator Facility (CEBAF, now Thomas Jefferson National Lab). At the time, both the copper and the superconducting RF technology were limited to acceleration fields of about 10 Million volts per meter, which made the proposed linacs very long and expensive. In addition, both technologies required a very large number of RF sources ('Klystrons') which greatly increased the costs of the proposals, which were not pursued.

THE MARCH OF SUPERCONDUCTING RF TECHNOLOGY
     Throughout the 1990's great strides were made in Superconducting RF Accelerator Technology. The success of superconducting RF systems at CEBAF and LEP showed that large systems of this type could operate reliably.
     The accelerating gradients also increased dramatically. A milestone in this was achieved in 1993 when a Cornell/Fermilab/DESY collaboration demonstrated that >20 MV/m could be obtained in a multi-cell superconducting cavity -- a result which cut the linac length by half compared to existing technology. Progress continues today, with experimental cavities at KEK, Cornell, and DESY using electropolishing techniques to approach 45 MV/m -- very near the theoretical limit of the materials. The Proton Driver design assumes an accelerating gradient of 25 MV/m.

TESLA
     The International TESLA Collaboration under the leadership of Bjorn Wiik made crucial contributions to SCRF technology. Compact and efficient cryomodules were developed, the RF power split and vector sum techniques were extended to drop the Klystron count by factor 36, and manufacturing of high-gradient cavities was established. These efforts culminated in the TESLA Technical Design Report in 2001, which laid out the system design and reduced cost of a linear collider based on these techniques. In 2004 the International Linear Collider Technology Review Panel (ITRP) selected the TESLA Superconducting technology as the preferred path to the linear collider.

SNS - The Spallation Neutron Source
     Another milestone in SCRF Technology was reached in 1999 when the Spallation Neutron Source, an approved project under construction in Oak Ridge, Tennessee by the US Department of Energy, was switched from a 1 GeV warm-copper linac to a 1.3 GeV superconducting linac. This was an extremely bold and foresightful move by the DoE, and a clear recognition of the cost advantages of the Superconducting Linac approach. The Main Linac of the Spallation Neutron Source was the starting point for design studies of the Proton Driver Linac.
     The SNS also began R&D on the 'fast ferrite phase shifter' technology crucial to extending the TESLA RF power split technique to proton linacs. Although this R&D was not ultimately incorporated in the SNS design due to schedule constraints, bringing this technology to bear on the Proton Driver linac is expected to bring substantial cost benefits from a greatly reduced number of Klystrons.

The 8 GeV Linac Proton Driver
     The modern concept for the 8 GeV Linac Proton Driver linac arose in discussions between Reinhard Brinkmann and G. William Foster in Snowmass of 2001. At the time, the main consideration was exploiting the very intense proton beams available from a high-energy Linac to ensure low emittances when using the Tevatron complex as an injector to the Very Large Hadron Collider (VLHC). The TESLA collaboration has recently documented a new cost-per-volt of Linac beam energy, and the selection of the Superconducting option for the Spallation Neutron Source provided a technical 'existence proof' for a superconducting proton linac.

Major design changes WRT the 2003 design study include:

1) TESLA - compatible operating frequencies are chosen

2) Two design points are documented:
      - An 'initial' design with 0.5 MW stand-alone linac beam power and 12 klystrons
      - An 'Ultimate' design with 2 MW stand-alonelinac beam power and 36 Klystrons.
   ==> Both designs support 2MW beam power from the Main Injector.

3) A new linac siting inside the Tevatron ring is documented.

4) The front-end linac is based on RIA-style superconducting spoke cavities.

5) The layout of the linac has been 'tweaked' to alow the use of unmodified
    TESLA/XFEL cryomodules in the main body of the linac.

6) An above-ground Klystron gallery has been chosen, in contrast to
    the 'two-ungerground-tunnel' approach taken in the 2003 Design Study." this.item8_1 = "2003 PD Linac Design Study" this.item8_2 = "2003 Synchrotron Study" this.item8_3 = "1999 Synchrotron Study" this.url8_1 = "http://tdserver1.fnal.gov/project/8GeVLinac/DesignStudy" this.url_target8_1 = "_blank" this.url8_2 = "http://www-bd.fnal.gov/pdriver/8GEV/index.html" this.url8_3 = "http://www-ad.fnal.gov/pdriver/oldpdriver/reports.html" //Sub Menu 9 this.menu_items_background_color_roll9 = "#f3e0c5" this.menu_xy9 = "0,-21" this.menu_width9 = 184 this.menu_shadow9 = "progid:DXImageTransform.Microsoft.DropShadow(Color=#999999, OffX=2, OffY=2, )" //Sub Menu 10 this.menu_items_background_color_roll10 = "#f3e0c5" this.menu_xy10 = "0,-20" this.menu_width10 = 175 this.item10_0 = "PD_GENERAL Mailing List" //Sub Menu 10_0 this.menu_xy10_0 = "3,-22" this.menu_width10_0 = 94 this.item10_0_0 = "Subscribe" this.url10_0_0 = "mailto:mbruce@fnal.gov?subject=Please%20add%20me%20to%20the%20Proton%20Driver%20GENERAL%20mailing%20list" this.item10_1 = "Agenda & Schedule" this.url10_1 = "../PD_General_Meetings.html" //Sub Menu 11 this.menu_items_background_color_roll11 = "#f3e0c5" this.menu_xy11 = "0,-21" this.menu_width11 = 174 this.item11_0 = "Meeting Minutes" this.item11_1 = "FESS Civil Drawings (.pdf)" this.item11_2 = "PD Civil Text" this.item11_3 = "DoE Space Bank Links" this.url11_0 = "http://tdserver1.fnal.gov/8gevlinacpapers/Meeting_Minutes/CivilConstruction/" this.url11_1 = "http://tdserver1.fnal.gov/8gevlinacPapers/FESS_Civil_Construction_Drawings" this.url11_2 = "http://tdserver1.fnal.gov/8gevlinacPapers/FESS_Civil_Construction_Drawings/CD-0-text-12.13.04/" this.url11_3 = "http://www.sc.doe.gov/sc-80/sc-82/spplan.shtml" //Sub Menu 12 this.menu_items_background_color_roll12 = "#f3e0c5" this.menu_xy12 = "0,-21" this.menu_width12 = 143 this.item12_0 = "PD_RF Mailing List" //Sub Menu 12_0 this.menu_xy12_0 = "3,-22" this.menu_width12_0 = 85 this.item12_0_0 = "Subscribe" this.url12_0_0 = "mailto:mbruce@fnal.gov?subject=Please%20add%20me%20to%20the%20Proton%20Driver%20RF%20mailing%20list" this.item12_1 = "Agenda & Minutes" this.icon_abs12_0 = 0 this.url12_1 = "http://tdserver1.fnal.gov/8gevlinacPapers/Meeting_Minutes/RF/Index.html" //Sub Menu 13 this.menu_items_background_color_roll13 = "#f3e0c5" this.menu_xy13 = "-1,-22" this.menu_width13 = 202 this.item13_0 = "Cryo/Module Agenda & Minutes" this.item13_1 = "Subscribe to Email List" this.url13_0 = "http://tdserver1.fnal.gov/8gevlinacPapers/Meeting_Minutes/Cryomodules/" this.url13_1 = "mailto:mbruce@fnal.gov?subject=Please%20add%20me%20to%20the%20Proton%20Driver%20CRYO%20mailing%20list" //Sub Menu 14 this.menu_items_background_color_roll14 = "#f3e0c5" this.menu_xy14 = "0,-21" this.menu_width14 = 157 this.item14_0 = "Meeting Minutes" this.item14_1 = "H- Transport Workshop" this.item14_2 = "Subscribe to Email List" this.url14_0 = "http://www-bd.fnal.gov/pdriver/meet.html" this.url14_1 = "http://www-bd.fnal.gov/pdriver/H-workshop/hminus.html" this.url14_2 = "mailto:chou@fnal.gov?subject=Please%20add%20me%20to%20the%20Proton%20Driver%20MI/Transferline%20mailing%20list" //Sub Menu 15 this.menu_items_background_color_roll15 = "#f3e0c5" this.menu_xy15 = "0,-21" this.menu_width15 = 118 this.item15_0 = "Mailing List" //Sub Menu 15_0 this.menu_xy15_0 = "2,-22" this.menu_width15_0 = 88 this.item15_0_0 = "Subscribe" this.url15_0_0 = "mailto:mbruce@fnal.gov?subject=Please%20add%20me%20to%20the%20Proton%20Driver%20FRONT%20END%20LINAC%20mailing%20list" this.icon_abs15_0 = 0 //Sub Menu 16 this.menu_items_background_color_roll16 = "#f3e0c5" this.menu_xy16 = "0,-21" this.menu_width16 = 243 this.item16_0 = "Ion Source Group Meeting Minutes" this.item_background_color_roll16_0 = "#f3e0c5" this.url16_0 = "http://tdserver1.fnal.gov/8gevlinacPapers/Meeting_Minutes/IonSource" //Sub Menu 17 this.menu_items_background_color_roll17 = "#f3e0c5" this.menu_xy17 = "0,-21" this.menu_width17 = 243 //Sub Menu 18 this.menu_xy18 = "0,-40" this.menu_width18 = 297 this.menu_shadow18 = "progid:DXImageTransform.Microsoft.DropShadow(Color=#999999, OffX=2, OffY=2, )" this.item18_0 = "Linac '02 paper on Proton Driver Concept" this.item18_1 = "Elba paper on Proton Driver Plans by R.
