Those detector designs are very elegent and, even better, very
maintainable.  For those not familiar with this product it is a
hemispherical chamber that can be used in a windowless or windowed mode,
easily disassembled and decon'ed, with replacement electrodes and windows.

What you really need is simply new electronics, assuming the single sample
system is all  you still need.

[On the other hand maybe I am being sentimental since this is one of the
first systems I worked with at NIST]
