Rotation

There are two ways to rotate the detector:

1. Use the left mouse button to click and drag the display

2. Click on the rotation buttons on the upper right hand side (each click results in a 90 $\deg$ rotation for quicker response).

The motion of the z-axis (by dragging the mouse in the up-down direction) is confined to a vertical plane normal to the screen (i.e. the neck of the acrylic vessel can only tilt towards or away from the viewer). Moving the dragged mouse horizontally causes the detector to rotate (spin) about the z-axis. (Note: Showing the D2O will drastically slows down the redraw speed. Also the performance goes down with the number of fired tubes. Use the crude rotation buttons instead of mouse dragging helps.)
