ELECTROSTATIC TRANSFORMERS FOR LARGE TOWERS
J. Colás, William A. Wenzel · eScholarship (California Digital Library) · 1989
In ion chamber calorimetry a large tower can be matched for fast signal readout to a low noise preamplifier using an electrostatic transformer (EST) as part of the tower structure.This is an attractive alternative to the ferrite core transformer, particularly inside a large magnetic field.The EST is most needed and most effective for the large hadronic towers, where the large ratio of area to perimeter minimizes the loss of spatial resolution from crosstalk with neighboring towers.
