The main stream of body elemental analysis is based on the delayed, prompt, and inelastic neutron interactions with the main elements found in the human body, and subsequent analysis of the measured delayed or prompt gamma ray spectra. This methodolo

The International Fusion Materials Irradiation Facility (IFMIF) Accelerator Facility consists of two 125 mA, 40 MeV cw deuteron linacs which provide beams to the molten lithium Target Facility. The reference design for the Accelerator Facility has ev

We will describe the operation of a cw rf driven multicusp ion source designed for extraction of high current hydrogen and deuterium beams. The source is driven at 2 MHz by a 2.5 turn induction antenna immersed in the plasma. Bare stainless‐steel a

Addition of cesium vapor to H−/D− multicusp volume sources has been shown to result in significantly increased extracted ion current density accompanied by reduced electron current density. However, using a cesium oven, the initial introduction o

The physics interest in a luminosity upgrade of RHIC requires the development of a cooling-frontier facility. Detailed calculations were made of electron cooling of the stored RHIC beams. This has been followed by beam dynamics simulations to establi

We describe the operation of a tandem accelerator based Contraband Detection System (CDS) built jointly by Advanced Energy Systems (AES) and TRIUMF, which employs the Nuclear Resonance Absorption (NRA) technique for detecting the attenuation of 9.17

The physical principles of the gamma nuclear resonance absorptiometry have been laid down quite sometime ago and have been used in many laboratories for studying nuclear structure. In the late eighties and during the nineties it become apparent that

A special dual function collar and getter strip holder subassembly was placed around the aperture of an rf‐driven multicusp source. With the source at 35 kV, and the rf pulsing at 24 kW for 1 ms at 1 Hz, the cesium in the getter strips was dispense

Space-based and other related accelerators have conditioning and operation requirements that are not found in most machines. The use of cryogenic copper, relatively poor vacuum, and limited power storage and operating time put unusual demands on the
