MarXperts is proud to be distributor (outside the Americas) of the world’s most advanced large area CCD-based X-ray detectors manufactured by Rayonix, LLC, USA.

The HS series is the latest addition to the line of CCD-detectors. It implements leading frame transfer technology that makes the new detectors as fast as pixel detectors (up to 140 frames/second) without compromising data quality and resolution. Thus, the HS detectors are ideally suited for experimental conditions where the read-out time of a detector becomes the bottleneck and not the amount of available X-ray photons, i.e. mostly on high brilliance synchrotron sites. Typical usage include high throughput single crystal crystallography including time-resolved studies, small- and wide angle scattering experiments (SAXS/WAXS), powder diffraction, X-ray computed tomography. Without the count-rate limitations of the competing pixel detectors, they are equally well suited for the upcoming X-ray electron laser beamlines (XFEL).

The detectors are available as single chip detectors (SX-30, SX-85) or as mosaic arrangements with 2x2, 3x3, 4x4 or 5x5 arrays with varying fibre optic taper sizes. In order to allow SAXS to pass through while measuring WAXS, scientists have been asking for an X-ray detector with a hole in the middle. The resulting LX series has a long, rectangular detecting surface, engineered with a notch to allow the direct beam and SAXS data to pass through.

Despite of their modular setup, the mosaic detectors come without gaps between the individual modules which is a considerable advantage over competing pixel detectors. The models differ most distinctively in the amount of built-in CCD-chips and the corresponding active area.  The following table gives an overview of specifications common to the entire series and point out the few relevant differences.


Highlights:

  • EXCLUSIVE SENSOR WITH HIGH SPEED FRAME-TRANSFER TECHNOLOGY:
    All HS-series detectors are based on a custom design CCD-sensor sized 3 x 3 cm with 1920 x 1920 pixels. A fiber optic taper is permanently bound to the sensor using a patented technology. The fiber optic tapers use demagnification ratios of 1:1, 1:2.6 or 2.92 yielding detectors with very large surfaces, depending on the amount of sensor modules.
  • LOW NOISE, ULTRA-FAST READOUT:
    Custom electronics provide ultra-low readout noise at high readout speeds: either 8e- in high speed mode or 4e- in low noise mode. The read-out time of a full frame is approx. 400 msec. With a typical binning mode of 2x2, the read-out time drops to 100 msec (10 frames/sec). With a 10 x 10 binning, a single frame is produced in 7 ms (140 frames/sec). The dead-time between images is 1 msec.
  • LOW TEMPERATURE, LOW DARK CURRENT:
    The CCD sensor is cooled to -80°C and protected inside a sealed vacuum chamber. The resulting dark current, less than 0.003e-/pixel/sec., allows exposures long enough for data collection from any crystal on any X-ray source. The refrigeration system requires only a standard electrical outlet and no cooling water.
  • FACTORY CALIBRATION:
    The detectors are calibrated carefully before delivery. Due to the permanent bond between the fiber-optic taper and the CCD chip, the instrument does not require routine recalibration.

Overview:

With the mardtb desktop beamline we bring all those nice features that users know from synchrotron beamlines to the home lab. It offers a very high degree of automatization. Virtually all movements are motorized. All motors are controlled by a micro-processor that can be operated via an Ethernet interface from a host computer.

Optionally, the mardtb goniostat can be controlled from a mobile device (Android, iOS coming up soon). Please look at the mardtb app page for more details.

 

Highlights:

Versatile: The instrument can be combined with any X-ray source from Mo sealed tubes to latest synchrotrons. The instrument accomodates either the mar345 image plate detector, the SX-165/MX-225 CCD detector, the PILATUS3 200K/300K/1M or the EIGER 1M/4M pixel detectors.
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 approx. 2 x 1.5 mm 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.
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.

"Desktop beamline" configurations:

mardtb desktop beamline with mar345 image plate detector 14 motors in standard configuration: The standard desktop beamline comprises motors for a PHI-axis (sample rotation), a Z-axis (horizontal sample translation), a CHI-swing (for easy cryo-mounting), a sample-to-detector translation stage, a 2-theta stage, a beamstop and 2 pairs of horizontal and vertical slits. The cardanic alignment system adds 4 more motors for translations and rotations of the instrument.
mardtb desktop beamline with mautomatic goniometer head 16 motors in automatic goniometer head configuration: The automatic goniometer head adds x- and y-translation translations to the goniometer head (the z-translation being a standard component), making a standard IUCr-type goniometer head obsolete. Sample centering can be done from the computer or via a local motor control box.
mardtb easymount: automatic sample loading mechanism 19 motors in easymount configuration: The easymount is a fully motorized sample mounting and retrieval mechanism. The easymount adds one motor for the cryo-cooler translation and 2 motors for the sample transport system to the automatic goniometer head configuration. Please see the “easymount” product page for more details.
marcsc automatic sample changer 22 motors in sample changer configuration: The sample changer adds 3 more motors for sample storage to the easymount configuration. Please see the “sample changer” product page for more details.

SX-165 CCD detector MarXperts is proud to be distributor (outside the Americas) of the world’s most advanced large area CCD-based X-ray detectors manufactured by Rayonix, LLC, USA.

The SX Series are the only CCD X-ray detectors that are ideal for both synchrotrons and rotating anode X-ray sources. The SX-165 features a round, 165 mm diameter active area, and a versatile, high-resolution CCD chip. The SX-165 is the upgraded version of the very successful marCCD X-ray detector. From macromolecular crystallography to small angle X-ray scattering (SAXS), the SX-165 is known throughout the world for unsurpassed imaging and excellent reliability. The SX-165 retains the same design and construction as the marCCD, but features a modernized and improved controller, and higher gain. It also has a frameshift mode of readout for time-resolved imaging on the order of milliseconds. The SX-165 can be used with or without the mardtb goniostat.


Highlights:

  • SINGLE CHIP, LARGE DETECTING SURFACE:>
    The SX-165 uses one 4kx4k chip, permanently bonded to a single fiber-optic taper, for simplicity and reliability. The monolithic design features a large, 165mm diameter circular taper imaged on a square CCD chip.
  • LOW NOISE, FAST READOUT:
    Custom electronics provide extremely low readout noise at high readout speeds. The SX-165 reads the chip from four channels simultaneously, resulting in a 2048x2048 pixel image in 2.5 seconds with less read noise than any comparable detector system.
  • LOW TEMPERATURE, LOW DARK CURRENT:
    The CCD chip in the SX-165 is cooled to -70°C and protected inside a sealed vacuum chamber. The resulting dark current, less than 0.01e-/pixel/sec., allows exposures long enough for data collection from any crystal on any X-ray source. The refrigeration system requires only a standard electrical outlet and no cooling water.
  • FACTORY CALIBRATION:
    The SX-165 is correctly calibrated before delivery. Due to the permanent bond between the fiber-optic taper and the CCD chip, the instrument does not require routine recalibration.
  • TIME-RESOLVED IMAGING IN MILLISECONDS:
    A newly-developed optional mode of data collection with the SX-165 makes taking data frames separated by only milliseconds possible. Frame-shift mode uses part of the CCD chip for imaging and the rest for data storage. After collecting the first image in the sequence, the CCD is triggered to quickly shift a configurable number of pixel rows, exposing fresh rows for the next image. Further triggers can make the CCD shift again and again until the CCD is filled up. It then reads out the entire CCD at the standard rate, and produces a corrected image showing a collage of the separate exposures.

Specifications:

  • Detector:
    • On-chip hardware binning - software selectable
    • Phosphor: Gd2O2S:Tb <40 μm thick
    • Closed-circle refrigeration at -80°C
    • CCD sensors are selected for low noise and low number of cosmetic blemishes. All defects are correctable and permanently mapped and corrected by our factory calibration procedure.
