Period: THIS MASER USED C. 1968 TO 1992. WAS OPERATIONAL IN 1993/94.
Canada: MASER WAS KEY ELEMENT IN PERMITTING NRC RADIO ASTRONOMERS TO BECOME THE FIRST IN THE WORLD TO CREATE A LONG BASELINE INTERFEROMETER (LBI) NOT PHYSICALLY CONNECTED BY WIRES. THE DEVELOPMENT TEAM, CONSISTING OF NRC AND CANADIAN UNIVERSITY SCIENTISTS, WON THE RUMFORD PREMIUM FOR THIS ACHIEVEMENT IN 1972. (REF. 1)
Function: TO MEASURE TIME WITH THE HIGHEST POSSIBLE DEGREE OF ACCURACY, AND TO GENERATE A VERY PRECISE TIME FREQUENCY.
Technical: ATOMIC HYDROGEN MASER PROVIDES HIGHEST POSSIBLE STABILITY OF TIME MEASUREMENT OVER PERIODS OF SEVERAL HOURS. THIS EXAMPLE WAS STABLE TO 1 PART IN 10(13)-10(14). IT'S SIGNALS WERE SYNCHRONIZED TO PERMIT COMBINING THE INCOMING RADIO DATA FROM ASTRONOMICAL OBJECTS SUCH AS QUASARS, ACTIVE RADIO GALAXIES FROM TWO OR MORE VERY DISTANT RADIO TELESCOPE ANTENNAS, SUCH AS THOSE OF THE LBI.
