Testing of a 1-MV linear transformer driver (LTD) for radiographic applications

A seven cavity LTD accelerator for radiography applications has been tested with a large area electron beam diode. Individual cavities have been tested with a resistive load. Results of these experiments have been compared to circuit simulations. The circuit model has been improved to provide good agreement with single cavity resistive load tests and seven cavity tests with an electron beam load. A simple modification was made to a single LTD cavity to reduce unwanted voltage oscillations.
