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.

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 |

Additional Specifications
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 or Windows Mobile® Device with Serial Connector.
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 (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
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.)


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, 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.

    Recon Ruggedized Pocket PC:The new-generation Trimble® Recon® handheld is as tough as ever. With an IP67 rating, it's impervious to water and dust, and inside the rugged casing it's packed with new connectivity options. As well as increased memory, and an industry-standard, open operating system, you now have the option of built-in Bluetooth® and wireless LAN.

    The Trimble Recon features a high-performance 200 MHz or 400 MHz processor, built-in Bluetooth wireless technology with the 400 MHz system and selected 200 MHz systems, and built-in wireless LAN with the 400 MHz system. All systems provide two CompactFlash (CF) slots, letting you add peripherals such as GPS cards, barcode scanners, or memory cards. You can also use the slots to add Bluetooth and wireless LAN cards to a 200 MHz Recon handheld.
    Key features
    -Ultra-rugged and lightweight
    -Integrated wireless options (Bluetooth and wireless LAN)
    -Two CompactFlash expansion slots
    -Windows Mobile version 5.0 software
    -GPS functionality easily added
    -TrimPix technology for wireless camera support

    RAP Scintillation Probes
    The CsI (Tl) crystal used in Radiation Alert® Probes has a higher atomic number, is more rugged, and less hygroscopic than a typical Nal detector. The improved gamma ray absorption allows a thinner crystal to be used, effectively reducing the background count rate.
