Abstract
This report discusses the design and performance of 2 Ramped Quadrupoles (RQ). They are to be used to rapidly move the horizontal tune close to the half integer (7.5) for extraction of the up to 1.0 GeV electron beam stored in the SHR. The design chosen is an 8 conductor array symmetrically placed about the beam axis at /spl plusmn/15/spl deg/ to the 4 axes and connected to produce a quadrupole field. The conductors are half imbedded in a ferrite shield assembly, outside a ceramic vacuum chamber, and when powered at 250 amperes produce a gradient of about 30 G/cm over the radius of 4.5 cm and along a 30 cm length. The ceramic chamber is internally conductively shielded to present a smooth bore surface for the S-band bunches, but allow the up to 20 kHz quadrupole field components to pass through the shield and influence the electron beam. >
