Top Level Task Summary
The NSCL data acquisition is a flexible distributed system. The data flow
through the system is shown schematically in the figure below:
Data flow in the NSCL Data Acquisition system.
Events are collected in a a Linux server system (spdaq computer) and made
available to other systems involved in the experiment across the NSCL data
acquisition network. These systems include Data U systems that you use for
on-line analysis and the DAQ server which has large event storage areas
on which event data are stored.
To build a complete minimal experiment you must:
- [ ]Create a Readout program that has been modified to
read your experimental apparatus.
This program will run in the spdaq system, and is responsible for
collecting events from your experimental electronics.
- [ ]Create a SpecTcl program that has been modified to
decode the event data from your Readout program.
This program will run in the data U systems for on line, and
nearline/offline analysis.
It can also be used for the early stages of off line analysis
once the experiment has finished running.
one or more of the data U systems.
- [ ]Run all of this stuff together under the data
acquisition system.
