    We present new time-of-flight electronics for atom-probe field-ion microscopy that is based on the LeCroy 2277/EXP2 time-to-digital converter (TDC) and is significantly superior to the commonly used LeCroy 4208 TDC. The maximum number of ions detected for each cycle is increased, the electronics...
