Description
The Longitudinal Forward Hadronic Calorimeter (LFHCal) is a sampling hadronic calorimeter which will cover the forward (hadron-going) region from $1.2<\eta<3.5$ in the ePIC detector at the EIC. The physics goals of the EIC demand strong jet reconstruction performance in this region to investigate small momentum-fraction $x$ phenomena. To achieve this, the LFHCal is constructed from alternating layers of steel plate and 5x5 cm scintillator tiles directly coupled to an SiPM, enabling fine segmentation in both the transverse and longitudinal shower measurement. A prototype LHFCal module was tested at the CERN Proton-Synchrotron T9 beam line in September of 2024 with electrons, muons, and hadrons spanning energies of 1 to 15 GeV. During the test beam, two different digitization schemes were utilized, one being a commercial CAEN product and the other based on the HGCROC readout designed for the CMS experiment. This contribution will present the first results from the HGCROC readout electronics.
