protondriver.doc - Proton Driver and Its Applications.doc


Proton Driver Section: Fermilab has recently completed a design study for a Proton Driver. It describes in detail the design of a new brighter booster, called the Proton Driver, as a complete functional replacement for the present Booster. The design report has been published as a technical memo FERMILAB-TM-2136. It can also be downloaded from the web: http://www-bd.fnal.gov/pdriver/reports.html. The Proton Driver is a rapid-cycling (15 Hz), high-intensity (3 × 1013 protons per pulse), 1 MW 16-GeV synchrotron. It serves a number of purposes in the Fermilab hadron program. In the near term, it replaces the present Booster and increases the proton beam intensity in the Main Injector by a factor of four, thereby providing an upgrade path for NuMI and other 120 GeV fixed target programs. It also opens the avenue for new physics programs based on its stand-alone capabilities as a source of intense proton beams. The beam power of the Proton Driver is a factor of twenty higher than that of the present Booster. It can be employed for the production of high-intensity secondary particle beams of pions, kaons, neutrons and neutrinos. In the long term, the Proton Driver can serve a neutrino factory and a muon collider by generating intense short muon bunches from a target. The design also allows an upgrade path to a 4 MW proton source by adding a 600 MeV linac and a 3 GeV Pre-Booster at some late time (called Phase II). To meet the requirement of a muon collider, such as a Higgs factory, the number of bunches in Phase II will be reduced to four. The main parameters of the Proton Driver in Phase I and Phase II are listed in Table 1. As a comparison, the parameters of the present proton source are also listed.
