Abstract: An X-ray photoelectron spectroscopy analysis system for analysing an insulating sample 20, and a method of XPS analysis. The system comprises an X-ray generating means 30 having an exit opening 32 and being arranged to generate primary X-rays 46,56 which pass out of the exit opening in a sample direction towards a sample surface 22 for irradiation thereof. It has been found that the X-ray generating means in use additionally generates unwanted electrons 258 which may pass out of the exit opening substantially in the sample direction and cause undesirable sample charging effects. The system further comprises an electron deflection field generating means 380,480,580 arranged to generate a deflection field upstream of the sample surface. The deflection field is configured to deflect the unwanted electrons away from the sample direction, such that the unwanted electrons are prevented from reaching the sample surface.

Abstract: A receiver produces complex data samples from a demodulated received signal. The data samples, which may form a preamble identifying a wireless LAN data burst, are arranged in a sequence comprising sub-sequences having a predetermined relationship with each other. A tuning frequency offset is determined by delaying the complex data samples by a plurality of different delay periods, auto-correlating the complex data samples using said different delay periods in order to produce respective auto-correlation outputs, determining a plurality of phase-dependent values each dependent upon phase errors in a respective auto-correlation output and calculating a value representing frequency offset by combining the phase-dependent values in a weighted manner. The preamble can be recognised by using the same delay means.

Abstract: A method of detecting a predetermined complex data sequence in a received signal, representing for example a broadcast burst preamble in a wireless LAN transmission, involves (a) performing an auto-correlation on the data extracted from the received signal to provide an auto-correlation output, (b) combining the auto-correlation output with a delayed version of the auto-correlation output to produce a combined output and (c) providing a signal representing the predetermined data sequence if the combined output meets a predetermined condition, preferably also taking into account the phases of the auto-correlation output.

Abstract: In an OFDM receiver the complex values of predetermined pilot sub-carriers are compared with expected values to determine pilot distortion values for those sub-carriers. The phases of the differences between successive values are determined, and then the rate at which these phases change with respect to sub-carrier frequency is determined. Data distortion estimates for other sub-carriers can be calculated by interpolation of the pilot distortion values such that the data distortion estimates have a phase which substantially complies with the determined rate.

Abstract: A flood gun 10 for charge neutralization of an analysis region Ra of a sample S downstream of the flood gun, comprising: a first source 30 of electrons; a second source 50 of positively charged particles; and an extraction and focusing assembly 60,64, arranged to: (i) extract a first, electron beam from the first source and focus the first beam to a first flood area Ae at the analysis region; and (ii) extract a second, positive particle beam from the second source and focus the second beam to a second flood area Ai at the analysis region. The electron beam and the positive particle beam may both be extracted and focused simultaneously, in a single mode of operation or, alternately, in a dual mode of operation. A corresponding method of providing charge neutralization and a spectroscopic system for secondary particle emission analysis are disclosed.

Abstract: A spectroscopic analyser and method of use, for surface analysis spectroscopy, are disclosed. The spectroscopic analyser 10 has a time-of-flight (TOF) spectrometer which analyses secondary electrons emitted from a surface of a sample 30 on excitation by an irradiation source 40. The TOF spectrometer includes a gate 50, which receives and selectively passes a proportion of the secondary electrons by pulsed deflection or retardation of the electron beam using gating members 55. In that manner one or more pulses of electrons enter a magnetic field-free flight tube 90 and reach a detector 120 downstream of the gate 50. The flight times, and therefore energies, of the detected electrons through the flight tube 90 are thereby detected. A curved electron mirror 100 may be used to increase the flight path of the pulsed electrons in the flight tube 90, thereby increasing the spread of each electron pulse within the analyser 10.
