neutronpy.instrument.Detector(shape, width, height, radius, hpixels, vpixels, tau=0.1, thickness=1, orientation=None, dead_angles=None)[source]¶ Class defining a neutron detector for Time of Flight spectrometer resolution calculations.
Parameters: - shape : str
Shape of the detector. ‘cylindrical’ or ‘spherical’
- width : list
Horizontal coverage of the detector from sample, where 0 is the angle of ki where it would hit the detector, in degrees.
- height : list
Vertical coverage of the detector from the sample, where 0 is the position of ki where it would hit the detector, in degrees.
- radius : float
Radius of curvature of the detector, i.e. the distance from the sample to the detector, in cm.
- hpixels : int
Angular acceptance of a single detector in the horizontal orientation, in arc minutes.
- vpixels : int
Number of detector pixels in the vertical direction
- tau : float, optional
Binning of the detector in microseconds.
- thickness : float, optional
Thickness of the detector in cm.
- orientation : string
Orientation of the cylinder, ‘horizontal’ or ‘vertical’, where the radius of curvature rotates around the horizontal or vertical axis, respectively. Required for shape == ‘cylindrical’.
- dead_angles : array-like, optional
List where dead angles are entered such that [start, stop], in degrees. If more than one range of dead angles, pass list of lists.
