+  * Check **[[s800 SpecTcl|Spectcl]]** window **S800_CRDCS_EFF.win** (see figure below) to verify the efficiency of the detectors.
+      * Start a new run recording data on disk
+      * Make a gate in spectrum **ic.sum** (top right plot) to select the Z region of interest, and call it **ic**
+      * Make a summing region around the "bananas" in spectra **crdc1.x.tac!ic** and **crdc2.x.tac!ic** (bottom left and right plots respectively)
+      * Stop the run and rescan data from disk
+      * Compare the number of event inside the 2D summing regions with the number of events inside the **ic** gate. Typically the former are very close to the later (nearly 100% efficiency for medium/high Z)
