At the forefront of modern X-ray structure work, the mar345 Image Plate Detector System offers you the most economic choice for recording diffraction patterns of small molecules as well as protein crystals. Furthermore, it is a powerful tool for use in the fields of powder diffraction, texture analysis, small angle scattering, and fiber and neutron diffraction.

Since its introduction in early 1997 as the successor to the extremely popular Mar scanners with 300mm and 180mm plates, the impact on the scientific community has been extraordinary. Close to 350 instruments have been installed by mid-2008. Found at almost all synchrotrons around the world, they are used as workhorses for all kinds of diffraction experiments. Likewise, they are very popular at both commercial and public research institutes.

You won’t find an X-ray detector with a better price/performance ratio anywhere!

With the Marresearch desktop beamline we bring all the great features users know from synchrotron beamlines to the home lab. It offers a very high degree of automization and virtually all movements are motorized. All motors are controlled by a microprocessor that can be operated via an Ethernet interface from a host computer.

• Versatile: The instrument can be combined with any X-ray source from Mo sealed tubes to the latest synchrotrons. The instrument accomodates the mar345 image plate detector or the Rayonix CCD-based X-ray detectors SX165, SX30-HS, SX85-HS, MX225, MX225-HE, MX170-HS, and MX225-HS.
• Automatic beam alignment: Thanks to a cardanic cradle, built-in ionization chambers, and full motorization, the instrument will align itself automatically to the beam by pushing a single button in the provided software.
• “Inverted PHI” geometry: The built-in CHI rotation stage allows the PHI-axis holding the goniometer head to swing up into a vertical position. This makes cryo-mounting really straightforward.
• Built-in video: An area of approximately 2mm x 1.5mm around the sample position will be displayed on the built-in LCD monitor sitting on top of the collimator. The video stream is redirected to a control computer.
• True 2-theta stage: A 2-theta motor allows for a vertical 30-degree rotation of a detector around the sample.
• Highly optimized cryogenic environment: The instrument provides a fixed mount for a range of cryo-cooling devices (Oxford Cryosystems, Oxford Instruments, Rigaku Xtreme, etc.). A cryo-stream exhaust with adjustable flow rate ensures a laminar flow of the cold stream around the sample and eliminates icing.
• Up to 22 motors: Depending on the configuration of the desktop beamline (see below), up to 22 motors can be found in the desktop beamline.
• Expandable: Up to 32 motors can be operated by the built-in, industry-standard, high speed serial CAN-bus architecture of the desktop beamline without having to change the controller hardware.

Take a state-of-the-art micro-beam sealed tube generator with specially designed high performance optics, add a mardtb “desktop beamline” and a mar345 image plate detector to it plus a cryo-cooler, put it into a shiny cabinet and you are getting a truly powerful yet very affordable complete X-ray data collection system—just perfect for macro-molecular crystallography, powder diffraction and related fields.

No water or electrical installations required—it will fit anywhere in your lab.

Components:

• Generator: Xenocs GeniX3D Cu HF (high flux) micro-beam X-ray generator operating at 30 watts, producing a microfocus spot with a size of 40 x 40 microns at the source. The new GeniX3D Cu HF source has been introduced in mid-2010 and replaces the GeniX Cu VHF. The new source makes use of another type of tube and newly designed optizimed optics. Despite running at the lower power of 30 W (50 kV / 0.6 mA) instead of 50 W used by the old system, the generator delivers a higher photon flux at the sample (see application note mar.AN28Oct10).
• Optics: State-of-the-art Xenocs multi-layer optic producing a spot size at the sample of < 190 by 190 microns FWHM (specs: see below). Other configurations, for example for a parallel beam or a Mo source, are available on request.
• Detector: mar345 image plate detector with 345mm diameter or a SX165 single chip CCD detector with 165mm diameter.
• Goniostat: mardtb “desktop beamline” multipurpose goniometer system, with the optional “easymount” or the marcsc sample changer extensions.
• Cryo-cooler: Optional Oxford Cryosystems “Cryostream 700” or “Cobra” low temperature unit.
• Table/enclosure: A functional and stable table with plenty of space for all electronics and attachments.

The marcam is a CCD camera coupled to a screen that converts X-rays into visible light. It will display an image of the direct X-ray beam in 20-fold magnification on a TV monitor.

Highlights:

• No X-ray leakage: The marcam comes with a set of adapters that allow you to couple it directly to the X-ray optics to be aligned. The beam is completely enclosed and the user does not risk exposure to scattered X-rays.
• Work with adequate light: Since the marcam displays the image of the beam on a TV monitor, there is no reason to turn the room lights off. Alignment procedures can be completed in adequate lighting to see small parts.
• Complete and portable system: The marcam is delivered in a briefcase-sized metal carrying case. It includes the camera unit, several adapters for use with different X-ray optics, all cables, and a stand with a magnetic base.
• Many applications: The marcam replaces the fluorescent paddle and pin diode. It is useful for aligning monochromators, multilayers, and focusing mirrors. It can also be used to check the focus of a rotating anode.
• Safety: The marcam eliminates X-ray scatter and leakage during the alignment procedure. It also frees the hand that traditionally holds the fluorescent paddle. Since the image is displayed on a TV, there is no need to lean into the radiation enclosure and get close to the beam to see the result of adjustments.
• 20-fold magnification: The large image displayed on the TV monitor makes it much easier to observe the effect of alignment adjustments. The customer can confidently choose the double diffracted beam and obtain maximum intensity and purity with certainty. This also makes the marcam a good teaching tool.
• Affordability: The marcam is priced to replace your pin diode and fluorescent paddle. Contact us for a quote based on your specific needs.
• Optional tabletop radiation enclosure.
