TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The system further comprises: a means for controlling the first magnetic field and the second magnetic field to change the direction of the electrons passing through it; and an ion guide (106) for receiving hydrogen ions that are liberated from the binding layer. The electron source further comprises: hollow tube and voltage source for establishing a voltage potential across the electron source to accelerate the electrons through the tube, where the voltage potential is equal to an ionization potential for the hydrogen molecules in the binding layer. The system (I) further comprises a means for controlling the magnitude of the first magnetic field and the second magnetic field; and the ion guide for receiving hydrogen ions that are liberated from the binding layer, where the ion guide is located concentric to the electron source. In the system (I), the electron source further comprises: tube and voltage source for establishing a voltage potential across the electron source to accelerate the electrons through the tube, where the voltage potential is equal to an ionization potential for the hydrogen molecules in the binding layer. In the system (I), the cells have hexagonal profile when viewed in top plan, circular profile when viewed in top plan or square profile when viewed in top plan. Preferred Method: The step (d) is accomplished by using a computer processor. The step (c) is accomplished by establishing the voltage potential for the electrons from the electron source that is equal to the ionization potential for hydrogen molecules in the binding layer and further comprises: (e) collecting hydrogen ions that have ionized from the binding layer. The step (e) is accomplished using the ion guide for receiving hydrogen ions that are liberated from the substrate binding layer, where the electron source is located concentric to the ion guide. The step (b) is accomplished using cells having hexagonal profile when viewed in top plan, circular profile when viewed in top plan or square profile when viewed in top plan.
