Dorfan is also working on the Milagro gamma ray detector where his main interest lies in ground level detection of Bursters. Milagro has the best chance of any detector of observing gamma rays from Bursters with energies exceeding 100 GeV. Such observations would put strong constraints on models that attempt to explain this fascinating, and mysterious, phenomenon.
Dorfan is heavily involved in analog electronics design for experiments. In particular he has been very active in the design of front-end amplifiers for several detectors and has promoted the use of custom integrated circuits for use on detectors.
