	The BCM system of the European Spallation Source needs to measure several beam parameters including pulse profile, charge, current, pulse width and repetition frequency. Moreover, it will measure differential beam currents using several ACCT pairs along the linac. This is particularly important at low beam energies where BLMs cannot be used for measuring beam losses. Due to the ESS-specific requirements, the BCM software and firmware will be customized. Also, parts of the electronics may need to be customized to be consistent with the ESS standard electronics platform, hence facilitate maintenance and maximize synergy with other systems. Technical challenges include maintaining signal integrity and a fast response despite large variations in the sensor cable length and ambient temperature, as well as minimizing the effect of the ground voltage fluctuations. This paper gives a general overview of the design and focuses on a few technical issues that are particularly important for satisfying the performance requirements. Also, BCM test results in laboratory conditions as well as preliminary results with the ESS ion source will be presented.

The BCM system of the European Spallation Source needs to measure several beam parameters including pulse profile, charge, current, pulse width and repetition frequency. Moreover, it will measure differential beam currents using several ACCT pairs along the linac. This is particularly important at low beam energies where BLMs cannot be used for measuring beam losses. Due to the ESS-specific requirements, the BCM software and firmware will be customized. Also, parts of the electronics may need to be customized to be consistent with the ESS standard electronics platform, hence facilitate maintenance and maximize synergy with other systems. Technical challenges include maintaining signal integrity and a fast response despite large variations in the sensor cable length and ambient temperature, as well as minimizing the effect of the ground voltage fluctuations. This paper gives a general overview of the design and focuses on a few technical issues that are particularly important for satisfying the performance requirements. Also, BCM test results in laboratory conditions as well as preliminary results with the ESS ion source will be presented.
