Cylinders are great in a sense. As you say the efficiency is awesome, but the standing waves make life complicated!

The GPU boom is causing big issues. Future projects are targeted at where we think GPUs will be in a few years, but you can never predict the crypto induced demand, and at the moment the price and availability is causing issues.

We already do make a quick full sky image, but unfortunately it’s not public. It’s actually a way easier problem than it is for MWA. Our antennas are on a regular grid, so it’s just a dense 1D FFT in each direction and we’re done. As the CHIME FoV is so narrow we tend to actually show just one column along the meridian against time, and that produces a lovely quick map of the sky.

The FRB boom has definitely helped the funding for everyone, and it’s been very successful for CHIME. Next stop, real time localization!
