Multi-Parameter Multi-Channel Analyzer System, MPA-3 Series
|
This third-generation, PC-based, ultra-high-speed, multiple input-parameter multi-channel analyzer (or Multi-Parameter Analyzer, MPA) is intended to simultaneously histogram multiple digital inputs from external sources, recording those events occurring within a defined coincidence time window as a single event, on an event-by-event basis. For dependent single- and multi-parameter acquisitions, coincidence resolving times can be set from approx. 150 ns to more than 3 ms in steps of 50 ns. A monitoring mode is available to view single or dual parameter spectra on-line during active data acquisition. Alternatively, each input of the MPA-3 can also be operated in an independent (non-correlated) MCA mode.
Designed as an ultra fast list mode system with input ports for 2, 4, 8, 12 or 16 ADC's, multiscalers or TDC’s (time-of-flight devices), the open system technology concept is capable of accommodating future system expansion. Each parameter input must be preceded by a compatible ADC (see FAST ComTec models 7070, 7072, 7074) or similar digitizing device. And two systems can be synchronized to provide a max. of 32 input channels. With list mode operation of the system, list data (sequential event-by-event data) can be stored on the local hard disk device or any other directly addressable storage device. Using a SATA hard disk drive data can be stored online at full throughput for many hours depending on the configuration. PHA Histogramming mode will enable the user to accumulate and histogram multi-parameter spectra in the RAM memory of the PC. Multiple windows of dual-parameter spectra can be simultaneously displayed. Any combination of ADCs can be selected. It is therefore possible to define several single- and dual-parameter spectra which can be simultaneously acquired and displayed. The counting rate capabilities are unmatched by any other multi-parameter System; with 7072 ADC’s we have observed counting rates up to 4.8 Mevents/s. The theoretical limit is 6 Mevents/s. This system requires a single PCI-type bus slot and a 32-bit Windows-based operating system (Window 98 or later, Windows XP recommended). Each base system includes a base module, PCI-based IO card w/ 4k memory FIFO, MPA-NT for SPA-3 operating software, and a base module to IO card cable. See individual data sheets for more details and specific features. See the Host PC Selection Guide for details regarding computer compatibility of these cards, not all PC's are compatible. |

| Multi-Parameter Analyzer (MCA) Systems, MPA-3 Series | |
|---|---|
| Selection Guide, Base Systems | |
| Model | Description |
| MPA-3/4P | MPA-3 Quad-Parameters Base System, 4 ADC digital interface ports. No ADC's included. Add Quad ADC Port Expansion Module for additional parameters (4 added inputs per Quad Module). |
| MPA-3/2P | MPA-3 Dual-Parameter Base System, 2 digital ADC interface ports. No ADC's included. For applications requiring only 2 input parameters such as X-Y detectors. Not expandable, cannot add Quad Expansion Modules. |
| Options, MPA-3 System 32-bit Windows based DLL Function Library Kits enable control of the MPA-3 System from external applications, including transfer of data. The programmers kit requires some programming expertise. There are no LINUX drivers for this system. List Mode data can be displayed by the MPA-NT operation software only in the format in which it was originally recorded unless the Replay option is used. Replay option software enables manipulation and processing of List Mode data for display in various formats (e.g. selecting smaller number of bits per parameter, different parameters, arithmetic operations, etc) that may be different from the format displayed during the original acquisition. |
