It is part of the LWS program of Science Missions and Targeted Research and Technology (TR&T) ground-based investigations that respond to the following questions: How and why does the Sun vary? How do the Earth and planets respond? What are the effects on humanity? SET uses existing data and new data from the low-cost SET mission to achieve the following: define the mechanisms for space environment effects; reduce uncertainties in the environment and its effects on spacecraft and their payloads; improve design and operations guidelines and test protocols so that spacecraft anomalies and failures due to environmental effects during operations are reduced."},{"1":"The SET-1 payload is flown on the Air Force Research Laboratory (AFRL) Demonstration and Science Experiments (DSX) spacecraft. The mission is baselined for a 6000 x 12,000 km, 42 degree inclination orbit with 1 year of operations."},{"2":"Payload Experiments for SET-1: Cosmic Radiation Environment Dosimetry and Charging Experiment (CREDANCE). Objectives: 1) characterize the energetic space radiation environment and its interactions with spacecraft; 2) provide data to other SET-1 experiments."},{"3":"Goals: 1) provide data to improve radiation environment models and design tools; 2) demonstrate the value of a compact space weather monitor in operational spacecraft."},{"4":"DIME1 is shown with five operating RadFETS along the bottom of the board and three UVPROM dosimeters. The board has a mass of 0.2 kg and requires < 0.5 W to read the sensors. The 27C64 is on the RHS and is the shorter of the three FGMOS memories. "},{"5":"Experimental details 27C64: A standard PROM programmed as a dosimeter. The dosimeter is passive and only requires power to read. An analysis of temperature effect yielded 20 flips per degree.  At doses above 1000 Rad the temperature effect was below the variation in readings and no adjustments were made for temperature. The raw data is provided for archiving. The .sequent files (mainly for the RADFET data) are available to the interested reader,  the board temperature is logged every second in COL H should this information be required."},{"6":"Main publications: 1) P.J.
