When using your PSD module, 2160A, Do I have to use other FAST ComTec modules, 2128 as a CFD ? I am not sure your PSD, 2160A can be used with other NIM module like the Ortec CFDD, 583B, and Canberra CFT SCA, 2035A?

In principle other CFD's can be used but our 2128A is far more sensitive than other such models.
     If you use an ORTEC 683 this will be fine (it has just half the counting rate capability though of the 2128A), the new 583 is most likely less sensitive and not as fast as the 683 and definitely much slower than the 2128A. As I am not an expert on ORTEC modules the customer can surely make a comparison based on our datasheet and the ORTEC modules he has.

I have scanned the initial publication about the 2160 - this might be of interest to your customer.
