The GCL is a combined Gamma Ray & Casing Collar Locator tool which provides a passive measurement of gamma radiation by means of a Sodium Iodide Scintillation Detector and identifies of changes metal thickness by means of a collar locator.
High voltage to the PMT is adjusted with temperature to maintain sensitivity over the whole temperature range.
