Ion TOF mass spectrum of CH2IBr recorded with TimepixCam after strong-field ionization with an intense 800 nm pulse (blue line) along with the camera images for each of the peaks in the TOF spectrum. Both UV and NIR pulses were present for this run, and the spectrum is integrated over all pump–probe delays. The (linear) polarization direction of the UV and NIR laser pulses was parallel to the ion detector and at an angle of approximately −30° with respect to the vertical axis in these images, which are integrated over a total of 35000 laser shots. The dark spot at the center of the detector and the intense pixel in the center for ions of mass 18 and lighter correspond to an area where overlapping hits were not properly identified by the centroiding algorithm due to the intense spatially localized water peak.
