MIRSI is currently in the lab in Hilo. We are working on ways to decrease the array temperature, having found several issues with the as-built cooling system. We are also replacing the array cabling and upgrading other aspects of the internal wiring and temperature sensors. The next cool down will show how cold the array can get without any electrical isolation. After that, the aluminum oxide electrical isolation will be put in to test the array temperature with the array's simulated heat load and with electrical isolation.
