TI - A Toroid Based Bunch Charge Monitor System with Machine Protection Features for FLASH and XFEL J2 - Proc. of IBIC2014 AB - For the superconducting linear accelerators FLASH and XFEL, a new toroid based charge measurement system has been designed as a standard diagnostic tool. It is also a sensor for the bunch charge stabilization feedback and for machine protection. The system is based on MTCA.4 technology and will offer a high dynamic range and high sensitivity. The machine protection features will cover recognition of poor transmission between adjacent toroid sensors, bunch pattern consistency checks, and protection of the beam dumps. The concept, an overview of the algorithms, and the implementation will be described. A summary of first operation experience at FLASH will be presented.
