Pixie Viewer is a graphical user interface written using IGOR from Wavemetrics (www.wavemetrics.com). It calls the user-accessible functions in the Pixie-500e driver to carry out the communication between the Pixie-500e modules and the interface. This graphical interface can be used to configure the Pixie-500e modules, to start, poll and stop a data acquisition run, or to display list-mode or MCA data read out from the Pixie-500e modules. It supports a multi-module Pixie-500e system with the capability of setting trigger distribution mode, coincidence pattern and other data acquisition options.

The Pixie-500e driver code comprises of a set of functions written in ANSI C. This driver was organized into a library through which Pixie users can call a few user accessible functions to implement the communication between the host and the Pixie modules. These functions translate physical quantities (number with SI units) into the bit patterns understood by the Pixie-500e 's on-board processors. This provides an easy-to-use interface for Pixie users to integrate the Pixie modules into their own data acquisition system. Sample code showing how to initialize or configure the Pixie modules, how to start or stop a run, and how to read data out of the modules will be provided to the users.

Please contact the Pixie-500e team at to discuss your application today!
