Progress Towards A 60 kg Bubble Chamber for Dark Matter Detection

The COUPP collaboration~has been investigating the use of bubble chambers for direct detection of dark matter. Our progress in developing a stable 2 kg CF3I bubble chamber with long superheated life time has led us to start construction on a significantly larger detector with a sensitive mass of 60 kg. I will give an overview of the challenges in engineering this detector and discuss the status of its construction.
