  • Fully compatible with many scintillation detectors and commercial tube bases.
ADC:
  • Fixed conversion 6µsec. computer selected conversion gain from 4096 to 256 channels depending on model.
  • Direct input accepts pulse peaking times of 0.5µsec. to 10µsec.
  • Includes dead-time correction when used in Live-time mode.
Amplifier:
  • On-board combination amplifier/preamplifier for use with scintillation detectors and photo multiplier tubes.
  • Course and fine gain from X1 to X160
Inputs:
  • BNC connector for direct connection to PMT anode signal.
  • On-board relays to bypass amplifier for use with positive unipolar or bipolar signals from external amplifier for alpha/beta spectrometers, 0-8 volt range.
High voltage output:
  • MHV or optional SHV connector
  • Fully regulated and controlled voltage
  • 2V increments from 0-1280 volts @ 1mA maximum current
Upper and Lower Level Discriminators: computer controlled over entire input range prior to ADC operation to reduce system dead time.
Modes:
  • MCA for pulse height analysis
  • Real time or live time operation selectable in 1 second increments in MCA mode
  • MCS for half-life and other time related studies
  • Dwell time selectable from 10mS to 600sec per channel in MCS mode
  • 100µsec to 500µsec for Mossbauer (requires optional subpannel TEL-ICSPCIOPT)
  • System dead time computed and displayed on screen during acquisition.
  • Zero level: 10 turn pot
Data Memory: On-board dynamic RAM, 1024, 2048, 4096 channel x 3 Bytes for data, plus region-of-interest flag.
Power: Supplied from PCI computer bus. On-board regulated for stability and noise rejection.
Software Specifications
ROI:
  • Screen shot of software in operation
    PEAK MARKERS OVERLAY THIS SPECTRUM FOR
    QUICK ISOTOPE IDENTIFICATION
  • Multiple regions of interest with color coding.
Modes:
  • MCA, preset real or live time, selectable.
  • MCS, dwell times from 10mS to 600sec per channel, selectable.
  • Preset count mode for selected channel, peak channel or gross
  • Region-of-Interest. Smoothing: 3 point smoothing of displayed data, (original data is unaffected).
Controlls:
  • Input selector
  • High Voltage
  • Amplifier Gain
  • Lower and Upper level discriminators
  • ADC Conversion Gain.
File: Save or load files and header information in binary or spreadsheet formats.
Calibration: Auto or manual 2 point linear or 3 point quadratic calibration converts cursor position reading to energy units or time units in MCS mode.
Subtraction:
  • Subtracts channel by channel the time normalized data that is stored in a background buffer
  • Overlay data memory spectrum with data in buffer.
Background Buffer: Used to store background spectrum from time normalized background subtraction.
Integral: When cursor is in ROI, computes gross area, net area with end point averaging, centroid and FWHM.
Peak Report: Displays ROI data, centroid, FWHM, gross and net integrals, and header information in spreadsheet compatible format.
ISOMATCH: A library text file with peak markers for overlaying the spectrum for quick isotope identification. Library can be edited or extended by using a word processor or text editor.
System: Operates under Windows 98 and higher.
Display:
  • Vertical scale adjust from 64 to 16M and LOG display.
  • Horizontal 1024, 2048, 4096 channels with expansion down to 32 channels.
