Meeting report for ePIC-EIC Roma2, April 24, 2024

Coordination Meeting

Attending: R. Ammendola, B. Benkel, M. Bondì, A. D'Angelo, A. Fantini, L. Lanza, G. Nobili, E. Sidoretti, E. Tusi.
1. General Points:
   
   • E. Sidoretti: improvements for the "camerona". The two FECs are now working. The HV has been connected to try the noise. The APVs are non the lateral bands (two boards). If a pedestal is done, the noise is under a threshold. There is a defect regarding an asymmetry between odd and even channels (under 45-50 adc), see photo. Red is a board and black is the other one, i.e. the X and the Y readout. We can notice a shift between odd (low noise) and even (high noise) channels. This is likely due to the fact that even channels are connected close to the mass, see photo. In the next steps the camerona will likely go to the oven and then it will be filled with gas.
   • A. D'Angelo: a first meeting for the disks has been done on Friday. Today a meeting with Pietro Antonioli will be held to assess an agreement between DOE and INFN. A document for the candidation of Roma2 to host the EIC collaboration meeting that will take place on January 2025 is going to be finished.
   • M. Bondì has produced a first simulation for the two disks, splitter in two parts, see figure.
