ABSTRACT . Single electron detection is desirable in systems incorporating EBCCDs. The sources of noise in single electron counting are discussed and an expression is given for the total noise. INTRODUCTION . Electron bombarded charge coupled devices (EBCCDs) have been recognized as having performance advantages over competing technologies in terms of their high sensitivity, low noise and high spatial resolution. ...
