photocathode

In current state-of-the-art accelerators, electrons are generated by shining laser light onto a metallic photocathode, which displaces electrons from the metal.

The material of the photocathode determines the wavelength detected by the intensifier.

The photoanode was grown onto a photocathode, which also contains a highly active, inexpensive, nickel-molybdenum catalyst, to create a fully integrated single material that serves as a complete solar-driven water-splitting system.

The photocathode of MGDD can be illuminated by an incandescent lamp with 250 W from the front side of semiconducting cathode.

The code has been validated on both chambers and it can now be applied to the 100 l detector with two main objectives: (i) rerun, as said, the background evaluation, possibly in parallel with older codes to check results and (ii) study the effect of growing detector dimensions on light loss and collection (i.e., variations in light yield, given the same used materials and photocathode coverage).

A UV laser-driven tantalum photocathode in a Pierce-type [42] electron gun assembly was used for generation of the probe electron pulses.

To ensure efficient hydrogen production, the a-Si:H/a-Si:H photocathode should preferably provide high photocurrent and operate near its maximum power point (MPP) during photoelectrochemical water splitting.
