S E International URSA-II Universal Radiation Spectrum Analyzer

PRODUCT INFORAMATION

URSA-II MCA – Universal Multi-Channel Radiation Spectrum Analyzer
The URSA II is a versatile radiation spectrum analyzer that is compatible with a wide range of radiation detectors. It is equipped with a full-featured MCA (Multi-Channel Analyzer) program that can extract and analyze data provided by your detector. The design of the URSA II incorporates feedback and suggestions from our existing URSA customers, ensuring a user-friendly and efficient experience.

Key Features:

Compatible with practically any radiation detector
Full-featured MCA program for data extraction and analysis
Internal switch in the battery compartment to suppress battery-charging circuitry when using non-rechargeable batteries
Weighs 391 grams (13.8 oz.) without batteries
Dimensions: 157 x 90 x 44 mm (6.2 x 3.5 x 1.7 in.)
Includes carrying case, USB-Serial adapter, NIM connector, MCA software with free updates, and AC wall plug

Product Usage Instructions

Switching the Power On/Off:
The URSA II features a power switch located on the device. To turn the device on, simply toggle the switch to the “On” position. When using non-rechargeable batteries, make sure to use the internal switch located in the battery compartment to suppress the battery-charging circuitry.
Connecting the Radiation Detector:
The URSA II is compatible with various radiation detectors. Refer to the user manual of your specific detector for instructions on connecting it to the URSA II. Ensure a secure and proper connection to avoid any data inconsistencies.
Data Extraction and Analysis:
The URSA II comes with a full-featured MCA program that allows you to extract and analyze data from your radiation detector. Install the provided MCA software on your computer and follow the instructions in the software manual to connect and retrieve data from the URSA II.
Maintenance and Updates:
It is recommended to keep your URSA II up-to-date by installing the free updates provided with the MCA software. Regularly check for updates on the manufacturer’s website and follow the instructions provided to ensure optimal performance and compatibility.

UNIVERSAL MULTI-CHANNEL 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. The fully quantitative Windows™ based URSA- II software package has been designed for ease of use in a Windows™ environment. Software options include URSA-II for WIN32, WIN64 and PPC software to run the URSA-II using a compitable PDA device. The software can be installed on as many computers as you like with no restrictions and includes FREE software updates.

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 µSEC. Wide gain range by utilizing coarse and fine gain controls, achieve gain from x1 to x250

Minimum System Requirements
Computer running Windows10 or 11. It has also been tested on Windows ME, 2000 and XE

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.

Switches
Power On/Off. An internal switch located in the battery compartment suppresses battery-charging circuitry when non-rechargeable batteries are being used.

LED Indicators
On/Off, External power availability, and charge Status

Power Requirements
External 12VDC power supply, six “AA” NiMH rechargeable batteries (included charging done internally), or six standard alkaline “AA” batteries (Not included).

Temperature Range: 32° – 122°F (0° to 50°C)
Weight: 391 grams (13.8 oz.) without batteries
Size: 157 x 90 x 44 mm (6.2 x 3.5 x 1.7 in.)
Includes: Carrying Case, USB-Serial Adapter, NIM Connector, MCA Software w/ Free Updates, and AC Wall Plug.

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 data collection from the URSA-II with user’s own software.
