Project X goals and organization Sergei Nagaitsev October 4, 2011

Sergei Nagaitsev, Oct 4, Motivation for Project X We want to build at Fermilab the most intense source of protons to drive the study of neutrinos and rare processes For neutrinos, need pulsed beam For rare processes, pulsed machines are not useful since accidental rates are the main limitation: we must use either synchrotrons with slow spill or CW linacs

Metrics to Measure Proton Accelerator Capabilities 1. Average beam power on target  By far, the most important metric 2. Beam energy on target  Muons: ~0.8 GeV – 15 GeV  Kaons: ≥ 3 GeV  Neutrinos: ≥ few GeV  Nuclear: 1-2 GeV 3. Bunch format (or bunch timing)  Small duty-factor for neutrinos (minimize background)  Special formats for NF/MC  CW for all others Bunch spacing depends on decay time Sergei Nagaitsev, Oct 4,

This science has attracted competition: The proton source landscape this decade... Sergei Nagaitsev, Oct 4,

Where are our competitors? The closest competition is from J-PARC  200 kW -> 1 MW at 3 GeV (RCS)  100 kW -> 0.7 MW at 30 GeV (MR)  However, operations split between fast extraction (2/3) and slow extraction (1/3)  Slow extraction plan: 100 kW by 2015 At present, only the Fermilab MI accelerator capabilities may be considered competitive… Sergei Nagaitsev, Oct 4,

6 Reference design configuration 3-GeV, 1-mA CW linac provides beam for rare processes program  ~ 3 MW; flexible provision for beam formats supporting multiple users  <5% of beam is sent to the MI 3-8 GeV acceleration: pulsed linac  Linac would be 1300 MHz with <5% duty cycle  Up to 200 kW beam power available at 8 GeV 3 3 GeV GeV GeV

Project X has a very strong support from Fermilab director and from the DOE In FY12 Project X will support ~35 FTEs (AD, TD, APC, CD, PPD and FESS) compared to ~25 in FY11 The SCRF program (led by B. Kephart) supports ~100 FTE (includes ILC and Project X) Other programs (e.g. HINS and Proton Improvement Plan) can also help us. Other labs (LBNL, ANL, India) are already contributing their own resources to help us. Sergei Nagaitsev, Oct 4,

Sergei Nagaitsev, Oct 4, RD&D Program Goal: Mitigate risk associated with technical, cost, and schedule uncertainties CW linac  The first ~20 MeV is key to the Reference Design concept.  Front-end, chopper, low-  acceleration, beam loss mitigation Pulsed linac  Pulsed linac has diverged from ILC requirements due to low current  Long-pulse beam operation,  =1 accelerating structures/modules MI/Recycler  H- injection; factor of three increase in beam intensity (relative to NOvA)  Injection, instabilities, rf systems Design development  Facility configuration including upgrade paths  Beam and e-m modeling; reliability analysis; MC and mu2e Task Forces  Note: SRF development for Project X is supported by the SCRF program (led by B. Kephart)

Sergei Nagaitsev, Oct 4, Front-End Test Facility We are preparing to build a prototype of the first ~15-30 MeV of Project X.  Validate the concept for the Project X front end, thereby eliminating the primary technical risk element within the Reference Design.  Wideband chopper; low-  acceleration  Operate at full design parameters Integrated systems test goals:  1 mA average current with 80% chopping of beam delivered from RFQ  Efficient acceleration with minimal emittance dilution through ~15 MeV Potential utilization in Project X facility following successful demonstration Collaboration between Fermilab, ANL, LBNL, (SLAC); India & China?  Oct 2016: Beam through  =0.1, 0.2 CM at ~15 MeV with nearly final parameters (1 mA cw, 5 mA peak, arbitrary bunch chopping)

Your effort Should be aligned with the project goals We welcome ideas that could save time and money  Reuse equipment where possible (and makes sense) Sergei Nagaitsev, Oct 4,

Your effort reporting Nobody should report 100% of effort to Project X (with a small exception)  ES&H training, department meetings, reading s, performance reviews are not Project X activities We will (generally) not accept people reporting less than 2 hours per week. Sergei Nagaitsev, Oct 4,
