“…The code emittance prediction is greater than the temperature model because the PBGUNS code also includes ion-optical extraction aberrations and space-charge effects. The PBGUNS prediction is close to other ion-source emittance measurements [14].…”

A 75-keV, 110-mA cw proton injector capable of pulsed operation has been developed for testing the LEDA 6.7-MeV cw radio frequency quadrupole (RFQ). Part of the preliminary development of this injector included operation of a 1.25-MeV cw RFQ at beam currents up to 100 mA. The 75-keV LEDA injector was modified to operate at 50 keV for these tests. We report here on the operational experience of the 1.25-MeV RFQ where 50-mA beam current was accelerated through the RFQ with 90% transmission. This half-power operation is of interest because (1) the injector beam current monitoring was more reliable, and (2) sufficient rf power was available to ensure the design cavity fields. These two features simplify the comparison of injector-RFQ performance with design codes. The information obtained from these studies will be applied to the 75-keV injector during the LEDA 6.7-MeV RFQ commissioning.

The High Intensity Light Ion Source SILHI is designed to be a prototype source for high power proton and deuteron accelerators. The aim is to achieve beam currents greater than 100 mA at 95 keV with rms normalized emittance lower than 0.2 F.mm.mrad. Installed at CEA Saclay, this ECR source delivered its first proton beam in July 1996. In February 1997, a 107 mA CW beam has been extracted through a 8 mm diameter extraction aperture (J = 213 mA/cm 2 ). A microwave power of 900 W at 2.45 GHz was needed. Diagnostic hardware, first beam measurements and last results are presented.

Advanced neutron interrogation systems for screening sea-land cargo containers for shielded special nuclear materials (SNM) require a high-yield neutron source to achieve the desired detection probability, false alarm rate, and throughput. The design of an accelerator-driven neutron source is described that utilizes the D(d,n) 3 He reaction to produce a forward directed beam of up to 8.5 MeV neutrons. The key components of the neutron source are a high-current Radio Frequency Quadrupole (RFQ) accelerator and a neutron production gas target. The 5.1 m long, 200 MHz RFQ accelerates a 40 mA deuteron beam from a microwave-driven ion source coupled to an electrostatic Low Energy Beam Transport (LEBT) system to 6 MeV. At a 5% duty factor, the time-average D + beam current on target is 1.5 mA. A thin entrance window has been designed for the deuterium gas target that can withstand the high beam power and the 2-3 atm gas pressure. The source will be capable of delivering a flux >1·10 7 n/(cm 2 ·s) at a distance of 2.5 m from the target and will allow full testing and demonstration of a cargo screening system based on neutron stimulated SNM signatures.
