Standard APD (10 mm x 10 mm PerkinElmer® chip)

ACE unit

Vortex® multi-cathode X-ray detectors feature the largest active area single element detector (~50 mm², 8 mm diameter) available of its kind. Vortex® detectors are produced from high purity silicon using state-of-the-art CMOS production technology. They feature excellent energy resolution (<136 eV FWHM at Mn Kα is typical) and a high count rate capability (input rate >1 Mcps). At a very short peaking time of 0.25 µs, an output count rate of 600 kcps is achieved. A unique feature of these detectors is their ability to process high count rates with virtually zero loss in energy resolution and no peak shift with count rate. The detector at XMaS features a 25 µm thick Be window mounted onto a KF-40 vacuum flange, reducing air absorption (old FET pream, no Cube-ASIC technology yet).

The MAR165 CCD camera is a 2D detector with a round, 165 mm diameter active area. It has overall dimensions of (WxHxD): 220 x 220 x 340 and has a weight of ~20 kg. It uses one 4k x 4k chip, permanently bonded to a single fiber-optic taper. The camera reads the chip from four channels (quadrants) simultaneously, resulting in a 2048 x 2048 pixel image. The readout time is ~5 seconds. The pixel size is 80 µm x 80 µm.

The MAR camera is controlled from SPEC, by specific macros, through a Linux device server running on xmas6 holding the camera controller card. The full MAR165 technical sheet is available here.

The Dectris Pilatus3 300K is based on the newly developed CMOS hybrid-pixel technology and operates in single-photon counting mode with a point spread function of 1 pixel only (FWHM). The detector has dimensions of (WxHxD) of 160 x 194 x 262 mm and weighs approximately 7.5 kg. It reaches a framing rate up to 500 Hz with a 0.95 ms readout time in fast mode. The pixel size is 172 µm x 172 µm. The active area has 487 x 619=301453 pixels and 83.8 x 106.5 mm² size. The detector has three modules with 17 pixels in the intermodule gap. The detector has a 20-bit dynamic range (counter overflow state 1048573) and a ~10⁷ ph/s maximum counting rate per pixel. It can operate in the ~3-36 keV energy range. An external 5V TTL signal can be used to trigger the detector.

Only available on request !!! This detector has dimensions of (W x H x D) of 384 x 100 x 458 mm and weighs approximately 12 kg. It reaches a framing rate up to 200 Hz with a 2.7 ms readout time in fast mode (100 Hz and 3.6 ms in standard operation) and has a pixel size of 172 µm x 172 µm. The detector features 1475 x 195 pixels (3 x 1 chips).

The Pilatus 300K-W consists of a detector head connected to a Linux acquisition workstation by a fiberoptic link. The detector head includes the detector module, the interface board with connection to the acquisition workstation, and power supplies. The acquisition workstation device server is based on the "LIMA" software library developed by the ESRF for 2D detectors control and 2D data acquisition.

The MAXIPIX is a fast readout, photon-counting pixel detector system developed by the ESRF and based on the Medipix2 readout chip developed by CERN and the Medipix2 collaboration. It has dimensions of 145 x 140 x 222 mm and weighs about 4.7 kg. The system achieves up to 1.4 kHz frame rate with 0.29 ms readout dead time and has a pixel size of 55 µm x 55 µm. The available detector features 512 x 512 pixels (2 x 2 chips).

--- A 1280 x 256 pixels (5 x 1 chips) detector is also available only on request!! ---

MAXIPIX consists of a detector head connected to a Linux acquisition workstation by a fiberoptic link. The detector head includes the detector module, the interface board with connection to the acquisition workstation, and power supplies. The interface board can drive detector modules implementing up to five Medipix2 or Timepix chips with simultaneous readout of each chip. The acquisition workstation device server is based on the "LIMA" software library developed by the ESRF for 2D detectors control and 2D data acquisition.
