The increased radiation environment and data rate for the High Luminosity Large Hadron Collider (HL-LHC) require upgrades to the readout electronics for the Muon Spectrometer ( MS ) electronics. In this talk, I will present the status of the irradiation studies for the chamber service module (CSM). The CSM is a custom-built front-end electronics board and is responsible for multiplexing data read out from on-detector electronics as well as passing configuration information to them. An important component of the CSM is a Field-programmable gate array (FPGA), specifically using the FPGA Artix7 xc7a35T, is responsible for fanout of configuration and control information for 18 mezzanine cards. The Artix-7 is a commercial component with a history of meeting our radiation specifications. The specific model used in the CSM was first tested for the Single Event Effects (SEE) at LANSCE. The model was tested in a radiation hard environment with an average flux 10^3 higher than ATLAS (6.02E+3 n/cm2/s vs 1.3E+6 n/cm2/s). Results show that the SEE test approximately had 3 years of ATLAS in comparison with 1.9E+11n/cm2/y fluence (MDT CSM Requirement). One CSM board on average has approximately 9 errors in 3 years of ATLAS Run. The CSM was next tested for the Total Ionization Dose (TID) at BNL. The model was tested at a dose rate 7.675 kRad/hr. Results show that the total dose of all four irradiated test boards exceeded more than 3x the ATLAS RTC requirement of 10kRad dose.
