XFlash^® Detectors

QUANTAX can be equipped with different models of the liquid nitrogen free XFlash^® 5000 silicon drift detector (SDD) series. You can choose between

• XFlash^® 5010 for applications that require optimum energy resolution and light element performance,
• XFlash^® 5030 if you use a cold field emission or an environmental SEM,

Note that both detectors are specified at a count rate of 100,000 cps. Energy resolutions down to 123 eV at Mn Kα are available. The members of this innovative detector family are also equipped with an optimized electron trap that permits interference-free analysis at even the lowest acceleration voltages in the electron microscope.

The current hybrid pulse processor SVE III combines analog and digital pulse processing techniques for optimal exploitation of the capabilities of our XFlash^® SDDs. A single signal processing unit can support up to four detectors simultaneously.

Spectra are collected by a digital signal processor and stored in the internal 4096*32bit MCA. The electronics unit provides versatile interfaces for full remote control as well as high speed data transfer.

The IO-Scan adapter board provides the interface between the signal electronics and the system computer. It allows the connection of up to four X-ray detectors simultaneously through the proprietary MegaLink interface.

A full featured scan generator for external beam control with wide range analog XY-outputs and software selectable scan resolution up to 4096 x 4096 pixels is included as well. It accepts two independent analog image signals (i.e., SE and BSE) and provides eight programmable pulse counters.
