Universal Radiation Spectrum Analyzer

SE URSA II Universal Radiation Spectrum Analyzer

The URSA II, with a full-featured MCA program, can be used with practically any radiation detector and can extract any data your detector can supply! It has been designed taking into account comments and requests from our current URSA customers. 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 defense | portal monitoring | education |

Software includes:

Fully editable standard libraries include all 497 isotopes listed in "Kocher's Radioactive Decay Tables"
Multi-channel scaling mode, peak search and identify, quanitification based on ROIs or peak search.
Dual-channel emulator allows use with gas proportional or phoswich detectors as a "gross alpha / beta counterscaler.
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.


Probe Connectors: 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 (5HV connector) and signal (BNC connector). Active detector input is selected via software and be negative, positive or pre-shaped (positive) signal.

External Connector: External connector provides +5V, +12V and -12V for external preamplifiers and two logic signals for notifying external devices of alarm conditions.

Switches: 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).

LED Indicators: On / Off, External power availability and fast charge activation

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

Temperature Range: 0°C - 50°C (32°F - 122°F)

Weight: 391 grams (1308 oz.) with batteries.
