Abstract :
The first one-meter long common coil dipole model (HFDC-01) has been fabricated and tested at Fermilab. This magnet has several innovative features such as: single-layer racetrack coils, a 22-mm wide 60-strand Rutherford-type cable made of 0.7-mm Nb3Sn strands, and a stainless steel coil-support structure reinforced by horizontal bridges inserted between coil blocks. The model was instrumented with voltage taps, quench heaters, temperature sensors and strain gauges in order to monitor the quench origin, and to study mechanical and quench protection issues. This paper summarizes the model design parameters, the fabrication procedures and the test results.
