Cherenkov Tank Setup
IceCube 2007 Home
Here is the inside of the tank. There are three optical
modules. The center one is stationary, held 1 meter above the
floor of the tank. The two side ones are mobile. They can
move to any height or horizontal position.
The large black frame serves as a support for a hood
as well as the O.M.s. The white liner is two layers of
tyvec. Visible on the left of the tank is black tubing that
circulates water through a U.V. filter. The tubing on the right
side of the tank is part of a water level meter.
Here is the tank, on its platform, with a second platform above it, and
incased in the PVC piping frame. The two platforms are used to
place SPASE scintillater boxes above and below the tank. The PVC
frame is used as a support for a large tent that surrounds the tank
completely to keep out light.
Here is the tent that went over the PVC frame. It is a black and white polyethylene
type material. With this setup the tank is light tight.
