Characterization of a Second-Generation Focal-Plane Camera Coupled to an Inductively Coupled Plasma Mattauch−Herzog Geometry Mass Spectrograph

Abstract: A second-generation Faraday-strip array detector has been coupled to an inductively coupled plasma Mattauch-Herzog geometry mass spectrograph, thereby offering simultaneous acquisition of a range of mass-to-charge ratios. The second-generation device incorporates narrower, more closely spaced collectors than the earlier system. Furthermore, the new camera can acquire signal on all collectors at a frequency greater than 2 kHz and has the ability to independently adjust the gain level of each collector. Each col… Show more

“…Sector-field instruments in general and MH-Mass spectrometer in particular call for high acceleration of relatively low mass ions for best performance. Accordingly, we observe a strong kinetic effect induced artifact on the IonCCD signal when coupled to a MH-Mass spectrometer: a very distinct negative peak located at the low mass side of the respective positive ion peak is observed, as reported in an earlier publication [32,34].…”

“…In the field of non-scanning sector-field mass spectrometry focal plane camera with CMOS technology [32] and IonCCD [1,2] were successfully used. Those latter detectors are, rather, charge collectors with no temporal resolution capability as they do not provide single-particle detection capability.…”

“…A previously described 128-channel Faraday-strip array detector [9] was used to collect all of the data presented here. This detector incorporates pixels of 45-m width placed on 50-m centers, which are tall enough to span the entire height of the magnet gap in the MHMS instrument (6.35 mm).…”

“…One example, the Focal-Plane Camera (FPC), has been tested with DOFMS and is depicted in Figure 5b [41]. The FPC is comprised of a 1-D array of ioncollection electrodes termed Faraday strips, each of which is connected to a dedicated integrating amplifier circuit [56][57][58][60][61][62]. The amplification circuitry is fabricated monolithically in silicon as a charge-integrating operational amplifier.…”
