For the AMANDA project the second generation Digital Optical Module electronics (PC board depicted to the left)  was developed here at LBNL. Many features of the design were strongly influenced by observations made on a 1997 trip to the south pole to deploy the first generation DOM developed by the NASA Jet Propulsion Laboratory.

Many scientists and engineers had a hand in  DOM development.  The grunt engineering work was done by Gerald Przybylski and Jozsef Ludvig.  Housings, photomultiplier tubes and deployment were organized by the University of Wisconsin.  On January 16, 2000, forty-one of these second generation DOMs were deployed on String 16 of AMANDA at the South Pole.


After the Jan. 2000 trip, the activity was reported on the web.  The IceCube experiment collaboration is currently proposing the DOM technology for IceCube, the follow-on to AMANDA.

Bob Stokstad, Gerald Przybylski, and Jozsef Ludvig did the last-minute fixes and final check-out of all DOMs deployed Jan. 16, 2000.

The AMANDA string 18 DOM contains fiberoptic components ultimately dropped from the IceCube design.
The printed circuit board is a little larger than 10 inches in diameter.
The PhotoMultiplierTube has an 8 inch diameter photocathode.
