uv energy detector

If the level of light to be detected is extremely low, look into photomultipliers. Wavelength sensitivity is set by the materials used for the photocathode. The material will be a metal, and will thus not degrade under the influence of the UV light like plastic or semiconductor material will. If the amount of light to be detected is large, try using a thermocouple detector, again with a metallic coating for the actual absorption of the light quanta. There is a large selection for each type of detector, so you can optimize to your application.

Since you have high energy concentration, the simplest would
be to use a regular simple vacuum UV photocell. I think metallic Zn would be the ideal cathode -- you could just measure the saturation current.

UV enhanced photodiodes will work and are generally less expensive the most UV Pototubes. Check out Edmund Scientific.
