Melinda,
I have an idea for a "quick & dirty" survey. Procure some black paper envelopes. Inside of these place a piece of x-ray film with a paper clip attached. Position these strategically around the instrument. One control should be kept in a different room, preferably in a meal box or wrapped in metal foil. A second control is intentionally exposed to the x-ray beam. This might provide some useful information. Even if it doesn't, in will certainly come in below $18K. It might give you useful information if the suspected leakage is diffuse rather than a collimated beam.

Subject: [DCHAS-L] Soft energy x-ray surveying
Hello, all,
I am looking for information about surveying services that provide testing for soft energy x-rays (i.e. 1-3 keV). We have a recently setup XPS system that we would like to survey to verify that it has no leakage. Unfortunately, the sole source that I was able to find for a suitable survey meter quotes a price of ~$18,000, so that option is a bit financially remote.
Anyway, any ideas or possibilities you might suggest much appreciated,
