The Detector Response Function Toolkit (DRiFT) post-processes radiation transport output from MCNP and simulates realistic gas, semiconductor, and scintillator nuclear instrumentation response. Scintillator response is the most mature DRiFT capability and includes the ability to simulate light production, photomultiplier tube (PMT) effects, and the digitization of the pulse, all important contributors when assessing an instrument's nuclear safeguards and nonproliferation applicability. Many scintillator, PMT, and digitizer models are supported natively by DRiFT, which also accommodates users adding their own specific instrumentation responses if absent in DRiFT. Until recently use of DRiFT required access to the high performance computing clusters at Los Alamos National Laboratory (LANL) and compiling the code with many additional software dependencies. This paper describes the development, capabilities, and release of an executable version of DRiFT compatible with Linux OS. In addition to scintillator features, many DRiFT diagnostic capabilities relevant to nuclear safeguards including source particle tracking, pileup estimation, cross-talk and correlated event identification, and varied output options are described.
