MythenDetectorSpecifications

MythenDetectorSpecifications contains all detector specific parameters, such as the number of modules, internal detector parameters like the strip width.

Note

The method read_bad_channels_from_file expects a text file using the format below. Each line denotes the index of a bad channel. Consecutive bad channels can be stored on one line e.g. channels with 20-42 are bad channels.

1
2
20-42
100
1002-1004

If youre file format deviates from the above format read youre file into a boolean numpy.ndarray and set the bad_channels directly.

class angcal._angcal.MythenDetectorSpecifications

Bases: pybind11_object

Variables:

  • min_angle (double) – Read-only static. Minimum potential detector angle (measured as displacement of first strip) [degree] (-180.0 deg)

  • max_angle (double) – Read-only static. Maximum potential detector angle (measured as displacement of first strip) [degree] (-180.0 deg)

  • bad_channels (numpy.ndarray of bool, shape (n_channels,)) – Expected size: number of channels/strips in the detector. Each element is True if the channel is bad, otherwise False.)

  • pitch (double) – Read-only static. Strip/channel width of Mythen detector [mm] (0.05 mm)

  • strips_per_module (int) – Read-only static. Strips per module for Mythen detector (1280)

  • num_strips (int) – Read-only. Total number of strips in Mythen detector

  • max_modules (int) – Read-only. Number of modules in detector. Default (48)

  • exposure_time (double) – Read-only. Exposure time [s]

  • bloffset (double)

  • dtt0 (double)

__init__(*args, **kwargs)

Overloaded function.

  1. __init__(self: angcal._angcal.MythenDetectorSpecifications, file_interface: Optional[SimpleFileInterface] = None) -> None

    file_interfaceOptional[SimpleFileInterface], default None

    A file interface to read bad channels file. If none is provided bad channel file is expected to be a text file where each line stores the channel index of a bad channel. Consecutive bad channels can be stored in one line by seperating the first and last channel index of the bad channel block e.g. bad_channel_index0-bad_channel_index1.

  2. __init__(self: angcal._angcal.MythenDetectorSpecifications, max_modules: int, exposure_time: float, num_counters: float = 1, bloffset: float = 1.532, file_interface: Optional[SimpleFileInterface] = None) -> None

    max_modules: int

    Number of modules in detector (default 48).

    exposure_time: double

    Exposure time in seconds.

    num_counters: int

    Number of counters active.

    file_interfaceOptional[SimpleFileInterface], default None

    A file interface to read bad channels file. If none is provided bad channel file is expected to be a text file where each line stores the channel index of a bad channel. Consecutive bad channels can be stored in one line by seperating the first and last channel index of the bad channel block e.g. bad_channel_index0-bad_channel_index1.
