What is Pychron

Pychron is a set of applications for the collection and processing of noble gas mass spectrometry data. Pychron is developed at the New Mexico Geochronology Research Laboratory at New Mexico Tech. Components of pychron are used within multiple research domains, but mainly for Ar-Ar geochronology and thermochronology. Pychron's main applications are pyValve, pyLaser, pyExperiment and pyCrunch. Additional components include RemoteControlServer.cs and Bakedpy.

Pychron aims to augment and replace the current widely used program Mass Spec by Alan Deino of Berkeley Geochronology Center

Give it a try

Interesting in seeing pychron in action? Don't want to/can't install all the required dependencies?

A demo version of Pychron Data Reduction aka PyCrunch is now available via a docker image. Checkout https://github.com/NMGRL/pychron_docker for more details

NOTE: this is an experimental feature and is likely to evolve over time

Who's Using Pychron

A number of Ar/Ar Geochronology and noble gas laboratories are using Pychron to various degrees. These include

  • New Mexico Geochronology Research Laboratory, New Mexico Bureau of Geology
  • University of Manitoba
  • WiscAR, University of Wisconsin
  • SWIRL, US Geological Survey - Denver
  • AGES, Lamont-Doherty Earth Observatory, AGES
  • US Geological Survey - Menlo Park
  • MNGRL, NASA-Goddard Space Flight Center
  • AEL-AMS, Ottawa
  • ANGL, University of Arizona
  • TAP, Purdue University

Installation of Pychron at other laboratories is ongoing. Current interested labs are

  • University of Florida
  • CAMS, Lawrence Livermore National Laboratory
  • University of Alaska, Fairbanks

Additionally, Remote Control Server, a script made by the pychron developers, is used extensively by the international community to interface third-party software with Thermo Scientific's Mass Spectrometer control software.

pyValve

Used to control and monitor a noble gas extraction line a.k.a prep system. Displays a graphical interface for user to interact with. A RPC interface is also provided enabling control of the prep system by other applications.

pyLaser

Configure for multiple types of lasers. Currently compatible with Photon machines Fusions CO2, 810 diode and ATLEX UV lasers. Watlow or Eurotherm interface for PID control. Machine vision for laser auto targeting and modulated degassing.

pyExperiment

Write and run a set of automated analyses. Allows NMGRL to operate continuously. only limited by size of analysis chamber.

pyCrunch

Display, process and publish Ar-Ar geochronology and thermochonology data. Export publication ready PDF tables and figures. Export Excel, CSV, and XML data tables. Store and search for figures in database.

furPi

Furnace firmware running on a networked RaspberryPi. RPC interface via Twisted for remote control

Mac OSX 10.9 and Later

Mac OSX and macOS operating systems later than 10.9 (Mavericks) include a memory management tool called App Nap. It is necessary to turn off App Nap for pychron. To turn off App Nap system wide use

defaults write NSGlobalDomain NSAppSleepDisabled -bool YES
