SEUSS

The instrumentation used during measurements with the beam is fully automated and is controlled from a dedicated personal computer. A customized software package, SEUSS (Single Event Upset System Supervisor), was written specifically for this purpose. A demo version of this software is available for download below.

Download the demo version of the software here.

Signal Inputs for Beam Control

A user-provided signal can be fed into our electronics to be counted as an "event". After setting the preset number of events to 1 (or any other positive integer) in the "Set run parameters"(http://cyclotron.tamu.edu/vladimir/SetRunParameters.htm ) and setting other presets to zero, the following runs will end when the specified number of events is reached. However, it may take up to 2 seconds after the last event before the beam is fully cut off. This is because the software checks the number of events once every second and the mechanical beam shutter may take up to one second to fully close.

The signal we use is NIM-type and our connector is BNC-type. However, we can use a NIM module (for example, EG&G Gate & Delay Generator) to convert TTL pulses to NIM pulses.

Input for the signal can be accessed at the patch panel in the data room or at the patch panel down in the cave.

Outputs

We also provide a beam on/off signal. this is +5V DC when the beam is on and 0 V DC when the beam is shuttered. There is BNC acess to this signal in the experimental cave as well as the data room.
