Pychron and the Spectrometer¶

Peak Hop Definition

Source Parameters¶

There are three ways in which pychron can interact with the spectrometers sources settings.

Readonly - Pychron only reads the sources parameters from the spectrometer. For each analysis these values are saved to the pychron database in the meas_SpectrometerParametersTable.

!Pychron currently does not save the source values to the secondary database.!
Read/Write - Pychron sets the source parameters in the measurement script. By using a pyscript the user has fine-grained control of when and what values are set. See below for detailed description of setting source parameters in a pyscript.
Config Write - On startup Pychron sets the source parameters using values retrieved from a configuration file located at setupfiles/spectrometer/config.py

Setting Source parameters¶

Set source parameters individually by name

set_extraction_lens(103.4)

Set parameters using a configuration file located at setupfiles/spectrometer/config.py

set_source_parameters()
set_source_optics()

Values from the configuration file can be overwritten by specifying a parameter name and value

set_source_parameter(IonRepeller=134)

Detector Parameters¶

Interacting with the detector parameters is the same as with the source parameters. The deflection values are saved in the pychron database in the meas_SpectrometerDeflectionsTable
