IMAGING DETECTOR SYSTEMS
Quantar Technology's 3300/2400 Series Multichannel/ Multipixel ImagingTM Detector Systems are position-sensitive, quantum-limited, charged-particle and photon detectors designed primarily for scientific, analytical and industrial research applications involving spatially-resolved analysis of events occurring from inherently weak signal-generating processes, demanding high detector performance. These high performance detectors are ideal solutions in a wide range of 1-D parallel multichannel spectroscopy and 2-D X-Y imaging applications. Complete systems comprise a MCP/RAE detector head, signal processing and readout electronics, and PC-based data collection and display hardware and software.
3300 Series MCP/RAE Open-Face Sensors (OFS/detector heads) utilize MCP (microchannel plate)
imaging electron multipliers followed by a charge-division position-encoding
anode. Operating in high vacuum environments, these detectors provide true, single-event, position-sensitive detection of electrons, positrons, positive and negative ions, neutral particles and EUV
and soft X-ray photons (10-200 nm)
directly on the MCP input surface. Higher energy X-rays
(>2 KeV) can also be detected directly by MCP's with decreasing efficiency at
higher energies. Detection efficiency for various types of
particles and photons is determined primarily by the MCP surface response or by
applied enhancement coatings. For use with 2400 Series Electronic Position Analyzers.
The Model 2401B is a 2 axis (X, Y), pulse-position processor consisting of a
separate, modular 4 channel charge-sensitive
preamplifier/shaper with added fast look-ahead channel and a main electronics module (19" rack mount unit)
containing signal processing, metering, edge-gating and
power supply circuits. Designed to be used with a 3300 Series Sensor; two preamp gain options are
available to match MCP/RAE sensor head types. The position analyzer has a count rate capability of up 100,000 counts/sec and has real-time display as events occur. CE-marked versions available for
European installations.
2200 SERIES DATA COLLECTION SYSTEM
See the FAST Comtec MPA-3 System for a Windows-based, PCI card data aquistition system. This system will use the analog outputs from the 2401B position analyzer, fed into a NIM-module type ADC. Though not specifically design for the Quantar imaging system, it is a good fit and design offering much flexiblity in varying applications, including coincidence timimg applications.
The 2200 Series Data Collection System was specifically design for the use with the Quantar imaging systems and functions as a one or two dimensional, PC-based
multichannel analyzer (multiparameter MCA). It is a DOS-based system and requires some legacy PC equipment with a minimum of EGA backwards-compatible color
graphics adapter/monitor and ISA-type available expansion
slot for IO card. The system consists of a Histogramming Buffer Memory (Model 2412A or
2415B), Parallel IO Card (Model 2420B), 11001A Data
Cable and MCA Software (either 1D or combined 1D/2D
version). The Histogramming Buffer Memory board is installed in
Model 2401B and is designed to be used with the digitized output options available for the
Model 2401B.
2601 SERIES IMAGING DETECTOR SYSTEM
Ultimate, true single-photon-counting for superb ultra-low light sensitivity with high signal-to-noise. Exhibits far lower detector noise than CCD cameras. Spectral ranges from below 180 nm to above 900 nm, depended on the choice of photocathode. Exceptionally low detector dark count, typically less than 10-5 counts/pixel/sec in 2-D mode at -25 deg C, with no CCD- type readout noise. Large 23 mm circular active area enables maximum light collection from experiments. High spatial resolution, typically better than 55 microns FWHM across full 23 mm active area. Virtually unlimited time-integrated dynamic counting range with digital counting avoids pixel count saturation. Remarkable 100 psec FWHM single-photon time-resolution available (optional subsystem) combined with single-photon imaging for time-resolved spectroscopy and mapping. Real-time XY photon display, low cosmic- ray sensitivity, simple operation, user-friendly. Complete, integrated and factory-tested detector system with optional PC-based data collection and display systems. Reliable operation and dependable support.
