MerlinX

 

The Merlin photon counting detector system with Medipix3 ASIC packs a lot in for its size.  With a vast range of applications, Merlin is a high performance X-Ray imaging detector that requires no additional cooling system, and being around the size of a mobile phone, is easily installed into small spaces. The system is supplied with a LabView GUI to get you up and running quickly while TANGO and EPICS drivers have been written to allow you to integrate it into your system.

Key Features & Benefits

  • Photon Counting – Zero Dark Noise
  • No Dead Time Between Frames
  • Spectroscopic Imaging
  • No External Cooling System
  • Compact Size
  • 55  μm pitch
  • 21,000 – 900 Hz depending on bit depth
  • 5 – 17 keV Range
  • 1, 6, 12 and 24 Bit Counter Modes

MerlinX is fast. Allocated to each of its 55µm pixels are 2 x 12 bit counters which allows continuous read/write with no dead time between frames.  MerlinX is available with either as MerlinX – a single Medipix3 chip (256×256 pixels) or Merlin4X – a quad (512×512 pixels)  system and has excellent sensitivity in the 5-17 keV range. The detector is installed at beamlines and laboratories globally, including several at NSLS-II, APS, DLS, PAL, SOLEIL, DLS, BSRF, and Spring-8.

Performance

The video shows a Merlin4X (512 x 512 pixels, 28.2 x 28.2 mm) recording a rotating chopper at a frame rate of 1KHz with no deadtime

Specifications

Rapid readout

Kilohertz frame rates in continuous mode with zero deadtime offers more experimental flexibility than ever before, minimising effects such as sample drift, and enabling single shot and “pump and probe” dynamic experiments.

Direct detection

Noiseless detection of single electron events.

Effectively noise free

Two threshold discriminators in each pixel means zero read noise and dark current.

Dynamic range

Up to 24-bit counting depth enabling 1:16.7 million intensity range in a single image, ideal for recording diffraction patterns.

Charge Summing Mode (CSM)

Communication between pixels designed to mitigate charge sharing effects for maximising both DQE and resolution.

No beamstop requirements

Radiation tolerant design means no need for a beamstop in diffraction experiments.

Software

The various acquisition modes, as well as many other input parameters for the optimisation of the MERLIN system, are easily chosen by a user friendly Graphical Interface as well as remotely controlled via TCP/IP protocol.
