Getting into the swing

Today (Day 2) we got into the swing of things and started our production lines to make dipoles and clip them onto the mesh (laid out last trip.)

We built our first full tile of the MWA!

It took us about 45 minutes to make the first tile (not including dipole building time) – here’s what it looks like sped up 1500%!

We then split into teams and started building large piles of dipoles and then putting together the tiles. We think we’ve worked out a good method of getting things done quickly, and we’re already speeding up and heading towards peak efficiency.  I’m cautiously optimistic that we’ll make it.

Cable tags for the dipole cables.

Cable tags for the dipole cables – these make hooking up the beam formers possible. If one cable on a beam former gets plugged into the wrong slot the tile doesn’t work and the images created don’t make sense. These little things are an important part of the telescope! (Photo Kim Steele)

Day 2 Summary

Antenna Count: 312/4096
Completed MWA Tiles: 6/128
Beam formers installed: 0/128 (0 on site)
