January 21, 2020: The PLASTIC team reports: All PLASTIC systems are behaving well, except there is a high background count rate, which seems to have a locus (a particular position, point, or place] toward the non-solar wind side of the instrument (which we call the WAP or Wide Angle Partition), which includes the ram direction. While we continue to monitor the background rates, we are gradually increasing the post acceleration voltage, alternating with short windows of exercising the entrance system.
PLASTIC measures the properties of the bulk solar wind and provides plasma characteristics of protons, alpha particles and heavy ions.
