The motivations and the concept for the multi-user upgrade of the ATLAS facility at Argonne were presented at recent conferences. With the near completion of the integration of the CARIBU-EBIS for more pure and efficient charge breeding of radioactive beams, more effort is being devoted to study the design options for a potential ATLAS mutli-user upgrade. The proposed upgrade will take advantage of the pulsed nature of the EBIS beams and the cw nature of ATLAS, in order to simultaneously accelerate beams with very close charge-to-mass ratios. In addition to enhancing the nuclear physics program, beam extraction at different points along the linac will open up the opportunity for other possible applications. Different beam injection and extraction schemes are being studied and will be presented.

Diversified Technologies, Inc. (DTI) has designed, built, and demonstrated a prototype pulse amplifier for stripline kicker service capable of less than 5 ns rise and fall times, 5 to 90 ns pulse lengths, peak power greater than 13.7 MW at pulse repetition rates exceeding 100 kHz, and measured jitter under 100 ps. The resulting pulse is precise and repeatable, and will be of great interest to accelerator facilities requiring electromagnetic kickers. The pulse generator is based on the original specifications for the NGLS fast deflector. DTI's planar inductive adder configuration uses compensated-silicon power transistors in low inductance leadless packages with a novel charge-pump gate drive to achieve unmatched performance. The prototyping efforts guided the design of the full unit, however the magnetics and transmission line effects of the system were not revealed until the entire unit was assembled. The unit was brought to LBNL, compared with other researcher's efforts, and was judged very favorably. A number of development prototypes have been constructed and tested, including a successful 18.7 kV, 749 A unit. The modularity of this design will enable configuration of systems to a wide range of potential applications in both kickers and other high speed requirements, including high performance radars, directed energy systems, and excimer lasers.
