Accutrol Systems Private Limited supplies Reverse Electrode Coaxial Germanium - REGe Detectors. Accutrol Systems Private Limited offers nuclear safety and security equipments. Reverse Electrode Coaxial Germanium - REGe Detectors is similar in geometry to other coaxial germanium detectors with one important difference. Reverse Electrode Coaxial Germanium - REGe Detectors are opposite from the conventional coaxial detector in that the p-type electrode, [ion-implanted boron] which is on the outside and the n-type contact [diffused lithium] is on the inside. It has two advantages of the electrode arrangement of the detector - window thickness and radiation damage resistance.
