The MDS is complete system consisting of one or more MPC-9604 subsystems, plus a PC and Protean control software. One MPC-9604 susbsystem is included for each four detectors. An exisitng MDS can be expanded by adding one MPC-9604 for each additional four detectors. |
The MDS is a third generation multi-detector low background system for gross alpha/beta counting. The MDS is the very best system available for applications requiring high sample throughput and high sensitivity. Labs doing Sr in drinking water, for example, often have many samples that require count times of several hours. Using one or more MPC-9604 four detector subsystems in parallel, the MDS can maintain very high sample throughput without sacrificing counting sensitivity. The MDS combines several critical features into one system. It has the lowest background performance in the industry for this system type. The MDS is expandable from 4 to 64 detectors by adding additional MPC-9604 subsystems. All MPC-9604 subsystems are supported by a single PC running appropriate Protean control software. Each detector in the MPC-9604 has its own individual sample drawer, making sample loading and control completely independent. There are no interrupted counts on adjacent detectors when any sample drawer is opened in the system. The MDS also supports true count to MDA, so counting time can be automatically optimized for each sample. GasPRO monitors the MDS for any P-10 gas fault and halts counting until it is corrected. The MDS is designed to minimize down time and to maximize counting efficiency in every possible way. It has the best maintenance features available in a multi-detector system. Detectors and detector windows are completely accessible from the front, without lifting a single lead brick. With no practice a detector window can be changed in less than 10 minutes, while leaving other detectors in the system operating! Every single electronic module is accessible from the front of the system; no rear access is required.
The MDS also has improved inter detector shielding. Older designs usually have little or no shielding between detectors. The MDS has about 2 inches of shielding between adjacent detectors, virtually eliminating counts from hotter than expected samples in nearby detectors.
The MDS is supplied as a true, turnkey system. It consists of at least one or more MPC-9604 detector subsystems, a controller PC with Windows™ operating system, and Protean application software. Protean control software is fully compatible with Windows XP™ and Windows 2000 Professional™. Protean control software does not require current or outdated versions of any spreadsheet or database applications in order to run. Each MPC-9604 unit contains four completely independent detectors, a guard detector, lead shielding, and all support electronics for that unit. The design of the MPC-9604 and control software allow easy expansion in the field. Each MPC-9604 subsystem is electronically self supporting, the only connections needed are to the PC, the P-10 gas supply, and AC power. Up to 16 MPC-9604 subsystems can be connected to a single control PC, for a total of 64 independent detectors. Since the PIC MDS is so easily expanded, you can start with a 4 or 8 detector system, and add more detectors at any time.
