URSA II Universal Radiation Spectrum Analyzer
The URSA II, a full-featured Multi-Channel
Analyzer program, is compatible with most scintillation detectors. The URSA II
system includes electronics and software. Customer may supply detector and
PC, but recommended models are available from us. Click here for the
Detector. The URSA-II MCA, the
all-new fully, quantitative Windows™ based URSA-II software package has been
designed for ease of use in a 32-bit Windows™ environment. Software also
includes URSA-II for PPC software to run the URSA-II using a Windows Mobile™
Device (Jornada, iPAQ, TDS Recon, etc.) running WindowsCE™ or Windows Mobile™.
The Software can be installed on as many computers as you like, with no
restrictions and includes free software updates.
Specific applications include:
Bulk sample analysis, air sample analysis, wipe sample analysis, thyroid assay,
compliance monitoring, environmental monitoring, nuclear medicine,
identification of unknown nuclides, remote monitoring, health physics, homeland
portal monitoring, education
• Fully editable standard libraries include all 497 isotopes listed in "Kocher's
Radioactive Decay Tables."
• Multi-channel scaling mode, peak search and identify, quantification based on
ROIs or peaks search.
• Dual-channel emulator allows use with gas proportional or phoswich detectors
as a "gross alpha/beta" counter-scaler.
• Sophisticated multiple alarm functions are based on the overall count rate,
individual ROIs, exceeding a specific rate or an increase in rate over a
specific time interval. Alarms can trigger external devices.
• Provisions are included for acquiring and saving spectra repeatedly and
continuously while unattended. Spectra can be saved and reloaded to "live" for
re-analysis or additional data accumulation, or loaded as a background spectrum.
Saved spectra can be superimposed on the "active" spectrum for comparison.
Spectrum format is easily accessible by a spreadsheet program. All reports can
be previewed, printed, or saved as text or rich text files.
• "ASCII" mode allows control of and data collection from the URSA-II with
user's own software or hardware.
4096-channels, can also be configured for 256, 512, 1024, or 2048 channels.
Internal bias voltage supply provides positive high voltage from 0 to 2000V at
up to 0.5mA (negative High Voltage available upon request). Adjustable shaping
time, 0.25 to 10 µs. Wide gain range by utilizing coarse and fine gain
controls, achieve gain from x1 to x250
Minimum System Requirements
486 computer running Windows 95® or higher. Connec
Detector Connector Two detector inputs. One standard series "C" connector for
detectors where the signal is joined with the high voltage supply. The other
is for detectors having separate connections for high voltage (SHV connector)
and signal (BNC connector). Active detector input is selected via software,
and can be negative, positive, or pre-shaped (positive) signal.
External connector provides +5V, +12V, and -12V for external preamplifiers and
two logic signals for notifying external devices of alarm conditions.
Power On/Off, and Fast/Normal charging rates. (Internal switch located in the
battery compartment suppresses battery-charging circuitry for when
non-rechargeable batteries are being used.)

External 12VDC power supply, six "AA" NiMH rechargeable batteries (included)
with recharging internally, or six standard alkaline "AA" batteries. External
12VDC power jack allows instrument to plug into vehicle. "Fast Charge" of NiMH
batteries can also be selected. The URSA-II is fully portable with four hours of
battery life and PPC Compatibility
