TECHNICAL SPECIFICATION FOR THE CONSTRUCTION OF AN RF SHIELDED ENCLOSURE

This Specification concerns the supply to CERN of an RF shielded enclosure of minimum internal dimensions 3.6m x 3m x 4m (LxWxH) to house the RF amplifiers of the Decelerating RFQ. The enclosure must have an attenuation ≥ 100 dB at 200 MHz and provide filtered connections for electricity, cooling water and control signals and non-filtered connections for low level RF cables, a 40 kV high voltage cable and a rigid coaxial RF line.
