New Maser Arrives!
New Sigma-Tau Active Hydrogen Maser Arrives
The maser will undergo several weeks of evaluation in the lab. At the completion of the tests the maser will be placed in the environmentally stable clock vault. It will then be allowed to stabilize for several weeks.
Plans are to have the new maser replace the Kvarz passive hydrogen maser as the Master Clock. This should occur about January 1, 2004. The new maser will be designated as HM-4.
