Description

The Multiport II unit is a double width NIM intended for use where existing amplifier and HVPS modules are to be combined with a high analog performance, low-cost ADC/MCA. It provides greater flexibility than traditional bus plug-in boards but at a comparable cost. The Multiport II NIM can be purchased in versions from one to six inputs. Units with fewer than six inputs can be field upgraded with additional inputs. Two communications interface versions are available: Ethernet/USB and USB only.

The Multiport unit is suitable for use with a wide range of radiation detectors. Selecting a proper preamplifier, amplifier and high voltage power supply, makes the Multiport unit compatible with NaI(Tl), HPGe, SiLi, CdTe, Ion Implanted, Plastic scintillation, BGO and other detector technologies. Modular NIM packaging makes it easy to reconfigure systems as needs change or as new technologies become available.

The Multiport II NIM is easy to install and easy to link. Host computer interfacing is accomplished via a standard USB port or a standard Ethernet port (UTP) and through standard protocols. These widely recognized interfaces make the Multiport II NIM compatible with a wide range of computer platforms, so the Multiport II user need not worry about compatibility as computer bus standards evolve. Also, multiple Multiport II units can be totally remote-controlled from a single computer. The Multiport II unit provides better performance and lower noise than plug-in PC board based MCAs by keeping all sensitive components out of the computer itself and by putting the MCA close to the radiation detectors. Furthermore, there is only one cable between the host computer and the Multiport II NIM module for simplicity of inter connection.

The Multiport II unit provides full I/O support, including Mirion standard PUR/LTC, sample changer synchronization and advanced PHA operations.

For more flexibility and more applications, the Multiport II unit supports both Pulse Height Analysis (PHA) and Multichannel Scaling (MCS) modes of operation. In MCA mode, a single channel analyzer (SCA) is also available as well as input/output that allows acquisition to be synchronized by external modules. SCA output works in both modes PHA and MCS. In MCS mode SCA pulses may also be selected as input pulses. The maximum input rate is 10 MHZ in TTL input mode.

Details:

Provides the Multiport II USB Genie 2000 driver for support on Windows 7 64-bit Operating Systems and Windows Server 2008 R2. This driver is compatible with Genie 2000 Version 3.3.

Note:

This release of the Multiport II USB driver (Version 1.0.0.3) has been tested with Windows 7 x64 and Windows 2008 R2 using Genie 2000 Version 3.3. For Windows 7 x86 and Windows XP operating Systems, the Multiport II Version 1.0.0.2 USB Driver should be used.

Version 3.3 of the Genie 2000 installation does not copy the Multiport II driver data files when installing on 64-bit operating systems. These files, DrMp2.DRD, MANUAL.DRD and PARALLEL.DRD are provided on the Multiport II driver installation disk and must be copied manually. The location for these files is the "C:\GENIE2K\DRIVERS\"; where "C:" would be replaced by the drive letter of the disk where Genie 2000 was installed. With these files in place you will be able to define Multiport II inputs using the Genie 2000 MCA Input Definition Editor.

Additionally the Genie 2000 installation does not create required registry entries for the Multiport II. The file MP2.reg is provided on the driver installation disk to create the required registry entries. Right click on the MP2.reg file and select the Merge operation to update the registry. Answer affirmatively to messages asking you if you really want to perform this update.
