LASP S EFFORT ON THE BABAR EFFORT WILL BE TO CONSULT ON THE PERFORMANCE REQUIREMENTS AND DESIGN OF THE RADIOMETER ARRAY AND ITS READOUT ELECTRONICS. FURTHER LASP WILL BE RESPONSIBLE FOR THE DESIGN FABRICATION AND TEST OF THE PROTOTYPE RADIOMETER ARRAY TO MEET THE REQUIRED PERFORMANCE IN THE COURSE OF THE WORK. THIS WORK IS THE NATURAL EXTENSION OF THE CURRENT AND ONGOING EFFORTS FOR BOTH THE COMPACT SOLAR IRRADIANCE MONITOR INSTRUMENT INCUBATOR PROGRAM AND SUBSEQUENT CUBESAT FLIGHT AS WELL AS THE CARBON ABSOLUTE ELECTRICAL SUBSTITUTION RADIOMETER DEVELOPMENT FOR THE CSIM AND CTIM INSTRUMENTS.
