The SuperBigBite Spectrometer Data Acquisition system in Hall A Jefferson Laboratory
ORAL
Abstract
The SuperBigBite Spectrometer has been used for several experiments since 2021 at Jefferson Laboratory in Hall A.
The first experiments used the BigBite and SuperBigbite Spectrometer to detect scattered electron in coincidence with neutrons or protons for GMn, and GEn measurements.
The main development in the data acquisition system was the GEM readout which constitutes the bulk of the data recorded. Other detectors mainly on the electron arm were readout by Flash Analog to Digital Converter or Time to Digital Converter. The bulk of the of the data is coming mainly from the 100s of thousands GEMs channels, a new layout of the CODA system was implemented to be able to handle up to 2.1 GB/s of data rate. Preliminary results from GMn and GEn experiment show the performances of the system and quality of the recorded data.
