ITECHINSTRUMENTSORIONThe ORION is the most advanced digital signal processor developed by ITECH INSTRUMENTS. It
is a 64K channel analyzer based with 100% digital
signal processing. The ORION features a 100 MHz 16
bit sampling ADC, an internal Linux computer, andinternal high voltage bias supply all supporting pulse
height analysis, list and peak shape data acquisition.

cation with a PC. Other LED’s confirm HVand warn of a system or detector problem.

The front panel of the ORION includes a 3.5” TFT
touch screen with autoranging display of peak counts
and a calibrated horizontal axis displaying energy.

Together with the InterWinner 7.0 software this makes the most advanced nuclear spectroscopy instrument on the market.

LED’s confirm serial or Ethernet communi-

The ORION for germanium, or the NaI version, arecontrolled by InterWinner software. ORION connects
to a PC via USB or Ethernet but ORION is a fully functional stand-alone spectrometer with spectrum storage.

Control software

The ORION system is usually used together withInterWinner 7.0, which allows the setting of all the parameters of the ORION. This includes analog gain settings, digital filters and thresholds, high voltage settingsand mode settings for the digital inputs and outputs.
Displayed information includes the voltages of thepreamplifier supply, the current value of the highvoltage and the status or the integrated counters.

InterWinner 7,0 with Germanium or NaI analy-

sis option, allows to create calibration files which
will be stored on the ORION itself. Such a calibration file includes an isotope table, an – optionally WinnerTrack created – efficiency curveand additional absorption corrections. TheORION then can autonomously calculate isotope activities using such a calibration.

Internal TFT screen

The ORION user interface is a modern smartphone-style touch screen interface. It comes inseveral languages, English, French, German,Italian, Spanish, Russian, Chinese. (Other languages to come in future firmware releases.)
The most frequently used functions are implemented in this interface. This includes:► Setting and enabling of the high voltage► Oscilloscope with trigger► Gain and input polarity settingSpecifications
Front panel controls► 3,5‘‘ TFT LCD touch screen► 6 LEDs

Back Panel connectors► BNC Signal input► BNC HV shut down input► SHV Positive HV output► SHV Negative HV output► BNC HV shutdown input► BNC TRP inhibit input► BNC Gate input► Automatic setup, including automatic energy calibration► Starting and stopping the acquisition► Spectrum display, including zoom and ROI marking► Peak search► Analysis, including activity calculation (Isotope table and efficiency have tobe prepared on the PC in advance)► Automatic spectrum storage► Recall stored spectra► Global gamma analysis including calibration of efficiency and background► Visualize the system health status► Export spectra on a connected USB stick► D-SUB9 Preamplifier power output► D-SUB25 Digital I/O, coun­ters, SCA
output, serial interface etc.
► DC power input (9-18 V DC)► RJ-45 Ethernet port
► USB-A USB host interface► USB-B USB device interface

Signal Input► Coarse Gain range is 1x to 362x
► Input polarity can be positive or negative► Conversion gain can be selected as 256,512,1024,

ITECHINSTRUMENTS► 2048,4096,8192,16 384,32768 or 65536 channels► Compatible with RC and TRP type detectors from different manufacturers

Operation Modes► PHA mode with up to 65536 channels► Time stamped list mode: Every event is stored
together with it‘s arrival time in units of 12.5
ns. The generated list also contains the statuschanges of up to eight digital trig­ger signals.
► Pulse shape mode: In this mode not only theevent energy but also the whole ADC for a selectable time before and after the event is stored► Multi-spectrum-scaling mode: This mode is
implemented based on the list mode and theWin­nerScan software. The events are sorted indifferent time slices after some external start event.
The durations of the time slices are multiples of12.5 ns, the number of time slices is practicallyunlimited. This mode is useful in decay studies.

Control processor► Internal Linux computer with 64MB RAM and256 MB (optionally + 1 GB) flash memory.
► TFT Touch screen► The ORION has two digital input on BNC
connectors for TRP inhibit and gate.
► In addition, the ORION has 8 digital inputs for sample
changer control, counting applications, external trigger
signals, synchronization and other applications.
► The ORION has 5 digital outputs (TTL) which can also
be configured as SCA outputs or synchronization.

High voltage power supply► Two SHV connectors for positive and negative high voltages► Programmable high voltage output► Setting resolution 12 bit.
► Voltage range ±500 - ± 5000 V (Germaniumversion) or ±500 - ± 2000 V (NaI version)► HV inhibit signal polarity is computer selectedHousing► Metal enclosure► Size: 173x84x180 mm► Weight: 1900 g

Power supply► External power supply accepting 50/60 Hz and 100-240 V

Internal spectrum storage► The ORION contains live memory forseveral spectra and a flash memory forseveral thousand spectra internally.
► Spectra can be transferred to the PC over Ethernet or by exporting them on an USB stick
