    Abstract: According to an embodiment of the invention there may be provided a system that may include a specimen chamber, an exchange chamber, a pressure monitor; and a controller. The exchange chamber may be configured to (i) receive a specimen when an exchange chamber pressure maintained within the exchange chamber is at a first pressure level, (ii) reduce the exchange chamber pressure to be lower than a specimen vapor pressure. The pressure monitor may be configured to perform, during a measurement period, at least one measurement of the exchange chamber pressure. The exchange chamber may be configured to stop a reduction of the exchange chamber pressure during the measurement period.

    Abstract: A method, a non-transitory computer readable medium and a system for compensating for an electromagnetic interference induced deviation of an electron beam. The method may include obtaining measurement information about a magnetic field within an electron beam tool, the measurement information is generated by at least one planar Hall Effect magnetic sensor that is located within the electron beam tool; wherein the at least one planar Hall Effect magnetic sensor comprises at least one magnetometer integrated with at least one magnetic flux concentrator; estimating the electromagnetic interference induced deviation of the electron beam, the estimating is based on the magnetic field; and setting a trajectory of the electron beam to compensate for the electromagnetic interference induced deviation of the electron beam.
