The above figure shows the output of a regular CDEM versus a rectangular Everlast design. The Everlast CDEM incorporates the theory discussed above directly in its manufacturing process. It has gone through extensive in-house testing and evaluation. A comparison of typical results of life tests performed at DeTech on standard CDEM's versus the Everlast CDEM appears in Figure 3. The term relative life is used as opposed to absolute life which depends upon a great deal of factors, such as operating pressure and proper handling.
Absolute life can also vary with the application.
These tests were performed in a controlled clean room environment under conditions which can be repeated precisely for comparison. A high input current was used to accelerate the testing process. Other inportant characteristics of detectors, such as noise, gain vs voltage, and detection efficiency are identical to those of standard detectors that are presently in use. The Everlast has also proven itself as a viable replacement for the discrete dynode electron multipliers. These are General Series 1000 Specifications and may be adjusted depending on specific model numbers.
