First Results from the IPHI Beam Instrumentation

I.P.H.I. is a High Intensity Proton Injector (C.N.R.S/I.N.2P.3; C.E.A./Irfu and C.E.R.N. collaboration) located at Saclay and now on operation. An E.C.R. source produces a 100 keV, 100 mA C.W. proton beams which will be accelerated at 3 MeV by a 4 vanes R.F.Q. operating at 352.2 MHz. Finally, a High Energy Beam Transport Line (H.E.B.T.) delivers the beam to a beam stopper. The HEBT is equipped with appropriate beam diagnostics to carry beam current, centroid beam transverse position, transverse beam profiles, beam energy and energy spread measurements for the commissioning of I.P.H.I. These beam diagnostics operate under both pulsed and C.W. operation. However transverse beam profile measurements are acquired under low duty factor pulsed beam operation using a slow wire scanner. The beam instrumentation of the H.E.B.T. is reviewed and the first measurements at 3 MeV are described.
