Portable USB spectrometer for detection of radon

Software for measurement and data processing for portable USB spectrometer

Medipix USB interface serves for Medipix2 data readout and acquisition control. It was designed with accent to maximum flexibility and portability. The interface can be controlled by Pixelman software.

Versions:

Version 1.1	First version distributed to Medipix2 users. Supports all versions of Medipix2. TimePix support is just partial.	Obsolete
Version 1.22	Currently distributed version. Full support of TimePix with selectable clock frequency (10, 20, 40 and 80 MHz), spectroscopic module integrated.	Spec. order
Lite Ver. 1.3	Very compact size of 60 x 15 mm. The interface (ver. 1.2) and Medipix2 (MXR) chip share the same PCB. Spectroscopic module integrated. Pict: [1] [2] [3] [4] [5]	First batch being manufactured
FITPix Ver. 2.3	FPGA driven, USB2.0 interface. Supports all chips (Medipix2, Timepix, Medipix3). Uses serial interface allowing 90 frames per second (for single chip).	Order here

Price depends on membership in international Medipix2 and Medipix3 collaborations. Please, indicate your status in the purchase order.

Pixelman is a software package for data acquisition and control of semiconductor pixel device Medipix2. It supports all available devices of Medipix2 family (Medipix 2.1, Medipix2 MXR, Timepix, Medipix 2.1 Quad, Medipix2 MXR Quad) and two interface types (MUROS and USB).

Pixelman can be for evaluation purposes freely downloaded here. Pixelman license is provided with Medipix USB interface or can be purchased separately. Pixelman license is given to all Medipix2 and Medipix3 members for free.

Technical support is available here (for licensed users).

In the field of X-ray radiography the image quality can be significantly improved by a beam hardening correction procedure especially if used in combination with pixel detectors of Medipix family. Two disk Filter Revolver is employed for calibration phase of beam hardening correction procedure. Each disk can be equipped by 7 calibrators so 49 combinations is possible. Calibrators are fixed in exchangeable holders with bayonet mechanism. Positioning of the filters is driven by stepper motors with electromagnetic brake using SMCU-7 and can be controlled directly from Pixelman software.
