A description is given of a small heavy-lon linear accelerator based on the use of a twin transmission line. Ions are accepted if their e/m values are 1/ 8 or greater (relative to the proton) and are accelerated to a final energy of 1.04 Mev/nucleon. The accelerator has 40 drift tubes fitted wlth focusing grids, and about 350 kw of pulsed rf are needed for ions of e/m = 1/8. The radio frequency is 25 Mc, and the accelerator is pulsed at up to 50 pps wlth a pulse length of 500 mu sec. Injection velocity is 0.007 c, corresponding to a do acceleration from the ion source through 180 kv from an ion of e/m = 1/8. Ions are produced in a pulsed dc arc of the Penning type operating ln a magnetic fleld of 1000 gauss, and the do accelerating voltage is supplied by an electrostatlc generator. Typical pulsed meter currents so far obtained are, for He/sup +/, input 4 ma, output 150 mu a; for N/sup 2+/, input 3 ma, output 75 mu a. The accelerator is the first stage of three, which wlll take the lons to a flnal energy of 10 Mev/nucleon. (auth)
