$f1(1285)$ formation in photon photon fusion reactions
Abstract We have observed formation of the f 1 (1285) in the reaction e + e - →e + e - π + π - η ( η → γγ ). Its γγ ∗ width is determined in several Q 2 bins. The γγ coupling parameter for the f 1 (1285) is found to be 2.4±0.5±0.5 keV. This value is compared to that for the X (1420), another J =1 state formed in γγ fusion reactions, which may belong to the same meson nonet.

MBE-4: an induction linac experiment for heavy ion fusion
The multiple-beam induction linac approach to a heavy ion fusion driver features continuous current amplification along the accelerator and a minimum of transverse beam manipulation from source to pellet. Current amplification and bunch length control require careful shaping of the accelerating voltages. This driver approach exploits developments in electron induction linac technology that have occurred within the last 15 years at LBL, LLNL and NBS. MBE-4 is a four beam induction linac that models much of the accelerator physics of the electrostatically focused section of a considerably longer induction accelerator. Four parallel Cs/sup +/ beams are electrostatically focussed and will be accelerated from 200 keV to approximately one MeV when the experiment is complete in the spring of 1987. The current in each of the four beams will increase from 10 to 40 mA due to both increase in beam speed and shortening of the bunch length. Results of experiments with the injector and first eight accelerating gaps are presented.
