FlatDetector

class marxs.optics.FlatDetector(pixsize=1, ignore_pixel_warning=False, **kwargs)

Bases: FlatOpticalElement

Flat detector with square pixels

Processing the a photon with this detector adds four columns to the photon properties:

• det_x, det_y: Event position on the detector in mm

• detpix_x, detpix_y: Event position in detector coordinates, where (0, 0) is on the corner of the chip.

The (x,y) coordinate system on the chip is such that it falls on the (y,z) plane of the global x,y,z coordinate system (it would be more logical to call the chip system (y,z), but traditionally that is not how chip coordinates are named). The pixel in the corner has coordinates (0, 0) in the pixel center.

Parameters:

pixsizefloat

size of pixels in mm

ignore_pixel_warningbool

ignore warning if derived pixel number is not close to an integer

kwargs

see args for optical elements

Define a new MARXS element.
