Abstract: Systems and techniques are provided for creating sensor based rules for detecting and responding to malicious activity. Evidence corresponding to a malicious activity is received. The evidence corresponding to malicious activity is analyzed. Indicators are identified from the evidence. The indicators are extracted from the evidence. It is determined that an action to mitigate or detect a threat needs to be taken based on the indicators and evidence. A sensor to employ the prescribed action is identified. Whether a sensor based rule meets a threshold requirement is validated. A configuration file used to task the sensor based rule to the identified sensor is created. The number of sensor based rule triggers is tracked.

Abstract: Temperature dependency on magnetic field strength of an electron optical element in an electron beam system due to variation of permeability with temperature of a ferromagnetic pole piece subject to radiant heating from another electron optical element is corrected by measurement of pole piece temperature and closed loop control of excitation current of a correction element which may be provided as a portion of a lens, stigmator, deflector or the like. A correction function may be computed to extrapolate correction values from empirically determined correction values or correction values may be retrieved from a memory such as a look-up table. Performance of the electron beam system is improved and constraints on choice of pole piece materials, mounting geometry, relative positioning of electron optical column elements and electron optical column length are relaxed since temperature dependencies of many electron optical elements can be corrected.
