Abstract:

IT WAS FOUND THAT THE INCLUSION OF A SMALL AMOUNT OF NITROCELLULOSE IN A COATING COMPOSED OF 75 Nd2O3 and 25 Gd2O3 had no appreciable effect upon the emission, except, perhaps, to cause activation to occur at a lower temperature. A cathode containing 90 Gd2O3 and 10 Nd2O3 gave an emission level less than 0.1 ampsq cm at 1400 C. Initial indications show that the high emission from Gd2O3 can be reproduced. The reason for the high activation is not yet known and needs further investigation. Author
