Popis:	The FASER experiment at the LHC aims to detect new, long-lived fundamental particles. A tungsten-silicon (W-Si) preshower detector is being developed to enhance the experiment's ability to distinguish between closely spaced photon pairs with energies on the order of TeV and separations as small as 200 \textmu m. This detector will use a monolithic silicon pixel sensor fabricated with 130 nm SiGe BiCMOS technology. Initial tests were conducted on the production ASIC, after evaluating the performance of the preproduction one. The first tests on the production ASIC indicate that the essential components of the monolithic silicon pixel detector are operating as expected. Two calibration methods were developed to reconstruct the charge of the FASER preshower detector, from the ASICs' ADC values.
