IRIXS reduction routines

Scripts for analysis of data collected on the IRIXS spectrometer, Beamline P01, Synchrotron Petra-III, DESY

• IRIXS: a resonant inelastic X-ray scattering instrument dedicated to X-rays in the intermediate energy range
• IRIXS Spectrograph: an ultra high-resolution spectrometer for tender RIXS

Overview

Reduction Classes

IRIXS.irixs: reduction class for the Rowland circle spectrometer
IRIXS.spectrograph: reduction class for spectrograph

• extracts raw collected images, transforms them into spectra and loads them to text files for analysis.
• basic plotting and fitting functionality

Scripts

p01plot: GUI application for quick plotting and fitting for experiments on P01 and P09
irixs_oneshot: check detector images from a specific measurement

Installation

Environment: Python 3.8+ w/ scipy + matplotlib + scikit-image + PyQT5

from PyPI:

1. pip install IRIXS

If using an anaconda/miniconda distribution, it is suggested to install dependencies separately:

1. pip install IRIXS --no-deps
2. then e.g. conda install pyqt

To symlink to the source folder instead:

1. Clone repository to a prefered location
2. Enter root directory
3. pip install -e .

Usage

IRIXS.irixs

Example reduction script for IRIXS.irixs

from IRIXS import irixs

expname = 'irixs_11009137'
a = irixs(expname, y0=667, roix=[160, 1500], roih=[-200, 200])

elastic_runs = [1713, 1719]
spectra_runs = [1710, 1711, 1712, 1722, 1723]

a.condition(0.006, elastic_runs, fit=True)
a.condition(0.02, spectra_runs)

fig, ax = plt.subplots()
a.plot(elastic_runs, ax=ax)
a.plot(spectra_runs, ax=ax)

IRIXS.spectrograph

Example reduction script for IRIXS.spectrograph todo

p01plot

p01plot [directory] [--remote -r] [--help -h]
directory : location to look for .fio data files
            defaults to /gpfs/current/raw, then current directory
--remote : remove cursor to speed up remote connections
--help : show this menu

irixs_oneshot

irixs_oneshot [number of run]
