Key Points

To enhance the data acquisition capabilities of the KLOE-2 upgrade by designing a new decoupling board.
Developed two new position detectors (HETs) for studying gamma-gamma physics.
Created a Data Acquisition (DAQ) system compatible with KLOE's existing systems.
Ensured electrical ground separation to minimize noise interference.
Successfully developed the DisOpto decoupling board for the HETs.
Achieved effective data transfer through VME bus and LEMO cables.
Reduced noise effects in the system, improving data integrity.

Abstract

For the KLOE upgrade (KLOE-2) we built a new couple of subdetectors: the HETs, two position detectors for electrons and positrons dedicated to the study of the γγ physics. The developed Data AcQuisition (DAQ) system of these two detectors is fully compatible with the data acquisition and trigger systems of KLOE. The DAQ of the HETs transfers the data to the KLOE acquisition through a VME bus while the trigger systems are connected through lemo cables. The electrical ground of the two systems must not to be connected in order to reduce the noise effects. This led us to develop a decoupling board called DisOpto.
