Development and test of single-layer common coil dipole wound with reacted Nb3Sn cable

Conference ·
OSTI ID:823127

The first one-meter long common coil dipole model (HFDC-01) has been fabricated and is being tested at Fermilab. This magnet has several innovative features such as: single-layer racetrack coils, a 22-mm wide 59-strand Rutherford-type cable made of 0.7-mm Nb{sub 3}Sn 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 propagation, and to study mechanical and quench protection issues. This paper summarizes the model design parameters, the fabrication procedures and the test results.
