Welcome to the ISSSort wiki!

The pages here are constantly under development. If you would like to have more details about how to install the code, pointers to examples of running it, etc, please get in touch with @lpgaff or feel free to add content yourself if you have access.

Capabilities and Philosophy of ISSSort

ISSSort takes raw data from the ISS experiment and performs all necessary steps to do a full spectroscopic analysis. It takes user input to define the configuration of the data acquisition, the detector inputs, energy and time calibrations, detector geometries and reaction parameters.

Data formats

It currently handles data output in the GREAT TDR data format from the Daresbury group, described here: https://nnsa.dl.ac.uk/documents/edoc504/edoc504.html

It supports data coming from the following systems:

  • CAEN digitisers; specifically V1724, V1725 and V1730 modules with data processed by MIDAS.
  • ISS4K modules; FPGA Mezzanine Boards (FMC) that process data from the R3B/ISS ASICs with data processed by MIDAS.
  • Mesytec digitisers; specifically MDP32 modules with data processed by Chalmers DAQ.

Input files

Basic process

  • Conversion of raw data to ROOT tree.
  • Time ordering of data items in a single file.
  • Event building by reconstructing individual particle events by detector type and correlating within a user-defined event-build window.
  • Physics histograms using the correlated events to make time-prompt/time-random coincidences, energy conditions, kinematic reconstruction, etc.
