# Gaugefields The `gaugeField` object, found in `latqcdtools/physics/gauge.py`, is a collection of `SU(3)` objects, described [here](../math/SU3.md). This is useful whenever one needs to store a configuration in memory. Such objects can be instantiated as ```Python gauge = gaugeField(self.Ns,self.Nt) ``` Its links can be read and manipulated through the accessors `getLink` and `setLink`. The `gaugeField` object is the place to set up basic observables. For instance one can already compute the plaquette using ```Python gauge.getPlaquette() ```
