PURPOSE

The purpose of the program covered by BuShips Contract No.

NObs-5358 is to refine and produce one thousand (1000) rugged X-band local

oscillator V-52 klystrons "• is tube is to comply with the specifications

of SHIPS E-720, which were subsequently modified at a conference held at

the Bureau of Ordnance, Washington, D.C. on 20-21 May 1952 and later at a

conference held at Varian Associates on 29-3C September 1952.

PROGRESS

During January five more V-52 tubes incorporating the short moly

drift tube drawn from sheet stock were constructed. Four of these tubes

were tested; one tube developed a leak at the window and had to be discarded.

The four tubes tested showed favorable results, having r-f characteristics

comparable to those of the standard V-52 (made with the long, drawn moly

drift tube). Frequency-temperature drift data were very satisfactory, with

the tubes being within specifications and only slightly overcompensated. These

results prove conclusively that good drift compensation can be obtained with

the short, drawn moly drift tube.

The synthetic mica mentioned in last month's report as a replacement

for the present mica window was tested in January. Windows with this material

were brazed into dummy bodies and then leak tested. All windows were found

to have leaks. Satples of the mica itself were then tested, and all were

found to be porous. The supplier has been advised of our findings and tests

have been discontinued pending availability of nonporous material. Investi-

gation, however, will continue in order to develop improved window manufacturing

techniques.

A post-assembly machining operation was eliminated this month on

an experimental group of tubes using pre-cut grids at the interaction gap

end of the drift tube. These grids formerly had been brazed to the drift

tube and then trimmed to size. With the pre-cut grids the trimming operation

becomes unnecessary. Test results will be available during the period of

the next report.

Because of high losses encountered in grid mounting operations, 2 a process mentioned in a previous report is again being investigated. This

process involves accurately silver plating the previously copper-plated drift

tube assembly. Subsequent firing with grids in position causes a silver-copper

alloy to form, which bonds the grids to the assembly. Grids so mounted have

been incorporated in tubes, but the tubes have net yet been tested. It is

believed that this technique, which eliminates the use of brazing rings pre-

viously used for mounting the grids, will reduce grid loss and speed up pro-

duction.

Emission troubles experienced last month seem to be clearing up,

although test results have net indicated a clear-cut cause. Studies into

the problem will cease if the present trend continues.

Investigations are being made to determine an improved configuration

for the reflector stem cup. It is believed that the force produced by expan-

sion of the silastic molding on the cup can be effectively reduced by a new 3

cup design .

Performance data of tubes tested in January are given in Table I.

this mcnth on the installation of all items of plating equipment, and very

satisfactory operation of this equipment is now being obtained.

PRO CRAM FOR NEXT INTERVAL

Improved techniques for window sealing will be investigated.

The new grid mounting techniques will be evaluated in the light

cf test results obtained from tubes incorporating these methods of manufacture,

Investigations into a new design for the reflector stem cup will

continue.

Estimated expenditures during January l°51i: $3'i,h36.00

Estimated man-hours during January l°5h: 28UU
