Abundant isotope collection is performed by a set of current amplifiers and CAMAC transient recorders. The current amplifiers are controlled by the computer and may be adjusted over a wide range.

The output of each current amplifier is connected to a transient recorder. A transient recorder is a type of list mode ADC. During each jumping cycle the transient recorders are individually clocked by signals from the gate generator at the appropriate moment to capture the value of the pulsed current waveform.

Usually each transient recorder is clocked once per jumping cycle. The isotope is sent to the offset Faraday cup by the beam jumping system, and a snapshot of the current value is taken and placed in the internal memory of the transient recorder.

Occasionally (approximately every 10 seconds) data collection is paused, and the list of measurements is uploaded to the computer where the information is placed in disk files for later processing.

Each time a block of data is uploaded numbers such as the average current and isotope ratios are updated in AccelNET.

NEC offers an option to this system which allows the transient recorders to be clocked more than once per jumping cycle. Using this option one can capture several datapoints within each Faraday cup current pulse and perhaps better quantify the measurement.
