$f1(1285)$ 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.

Printed-Circuit Steering Coils
Beam steering coils utilizing "turns" etched on printed-circuit boards have been constructed and tested. This approach offers an economical method for achieving high-quality, compact steering coils. The circuit-boards are rolled into a cylinder and inserted inside a short steel tube. Boards for vertical and horizontal steering are located in separate layers. For our application, three coil sizes were constructed with inside diameters of 25 cm. 20.6 cm, and 17.3 cm respectively. Active length is 0.6 of the inside diameter in all cases. The coils produce an integrated deflection field in either the vertical or horizontal direction of ~ 316 Gauss-cm when excited with 5 A at ~ 30V. The conductor pattern on the circuit-board was designed to produce a nearly uniform angular deflection for all rays transmitted, in spite of the short length/diameter ratio. The magnetic field integrated over a length of 152 cm was measured at several radii and azimuths. Values at 0.4 and 0.8 of bore radius were within ~ 0.5% and ~ 1.5% respectively of the central value. Suggestions for further refinement of deflection uniformity are presented.

PEP Insertion Quadrupole Design Features
The insertion quadrupoles for the PEP storage ring must have a very uniform gradient to focus the circulating beams to a very small size at the interaction point for high luminosity. Quads have been built which achieve the desired field within the full pole aperture radius to approximately one part in 104. The design features which permitted this achievement are described.
