These movies (animated GIF) simulate the filling of Borexino. They are large (~10MB) so should only be viewed from a high speed connection.

In these movies, the PC liquid level (n=1.5) is indicated by white lines along the x and y axes. The red vessel is the IV, with bright red endcaps. The green vessel is the OV, with bright green endcaps. The PMTs are indicated in blue by a circle defining the entrance to the light concentrators, a circle defining the photocathode, and a spot where they mount to the SSS. The white dots are the camera positions. Note that sometimes you will see multiples of items due to total internal reflection. Images are taken every 10 cm during filling, except when the level approaches the camera itself, when steps sizes are reduced to 1 cm. These are very close to what will actually be seen with the lenses we are using -- and include the fish-eye distortion. (Note: the large blue rings seen by camera 7 are due to the light concentrators of the adjacent pmt's blocking the view. We can perhaps avoid some of these by choosing a port with muon tubes next to the camera.)

Movie from camera 3: Theta=34.9, Phi=305
Movie from camera 4: Theta= - 34.9, Phi=5
Movie from camera 7: Theta=55.65, Phi=120 (tentative)

Here are some still shots (~250 kB GIF) at twice the resolution of the movies:

View from camera 3, level at 0.0 (equator)
View from camera 4, level at -250 cm (below equator)
View from camera 7, level at 250 cm (above equator)
