The nELBE Trigger Logic

The trigger logic of the nELBE data acquisition setup is realized by means of FPGA logic based on the CAEN V1495 General Purpose Boards. We developed different firmware for the "User FPGA" of this module that contains all logic functions needed for a proper operation of the different experimental setups.

• Trigger logic for inelastic neutron scattering⁽¹⁾

• Trigger logic for transmission measurements⁽²⁾
• Logic to control the absorber⁽³⁾

• Trigger logic for fission measurements⁽⁴⁾

The following table contains for each available User firmware the logic layout and an pdf file with register address map, configuration details and channel assignment:
