MONTHLY PROGRESS REPORT #6
PROGRESS FOR THE MONTH OF NOVEMER 1957
01
The high speed rotary joint was redesigned to eliminate radial play.
Drawings of the rotary joint housing have been released to the Model Shop.
Considerable work had already been done on a 1? antenna when it was
decided to change to a 2? antenna. In order-to have an antenna for laboratory use
as soon as possible it was decided to complete the 1? antenna. Two designs for the
rotating feed have been released to the Model Shop. A third design is now in pro-
gress. Models must be built to experimentally determine the best compromise between
performance and ease of manufacture.
A design for modification of the existing parallel plate horn to incorporate
a curved backwall has been completed and released to the Model Shop. The curved
backwall is a method of beamshaping and may be incorporated in the antenna to simpli-
fy the scanning system. An alternate design using beamshaping in the E plane has
been completed and released to the Model Shop.
Sketches of the 1? scanning head are 90% complete and Model Shop work is
40% complete. The 2? scanning head layout is 90% completed by Drafting.
Receiver-Transmitter
The layout of the R-T unit is about 50% completed by Drafting. A bread-
board R-T has been assembled and is being tested.
Modulator
A breadboard modulator using the transformers designed for the system has
been built and is being tested. Model Shop construction of the final unit is in
progress.

Model Shop construction of the Pre-Amp, and Post Amp. is 50% complete.
Control Panel
The layout of this unit has been completed by Drafting. Detail drawings
are now being made.
Synchronizer
Drafting has completed the schematic'and,main chassis layout. Layout of
subunits continues.
E - Scope
Vertical and horizontal subchassis have been released to Model Shop. MazinlI
chassis drawings have been completed but not checked.
Power Supply
The chassis layout is approximately
3015 complete. The voltage control boxes
ii
have been laid out and a Model built in the lab for stability tests, Drawings for
control box-covers have been made and submitted to electrofilm for their final
proposal on temperature control.
X- Scope
The completed breadboard has undergone laboratory evaluation in this
period. Most of the interference observed in the display has been attributed to
poorly regulated laboratory supplies. The RCA representative gave some assistance
in the proper operation of the storage tube,and revised some of the initial tube
data. The erase gun characteristics will continue to be under consideration.
The experimental optical system has been used with the indicator. Pre-
liminary evaluation indicates that the system will be adequate. Effort is being

directed to increasing light intensity of the screen. Details of the final optical,
system are presently being worked on.
The drafting phase of the X-Scope unit is well under way. Some detail
work has started.
System Performance Test
An investigation of various possible ways of making an in-flight system
performance checkwas made.
It was decided that the most feasible method was that of using an ultra-
sonic quartz delay line in shunt between the preamplifier and postamplifier. A
pulse sample from the maggy is converted to a 45 me pulse, by the receiver, and
hits the delay line and it rings with a decay rate of approximately 2 db per echo.
The echoes then disappear into the noise and by counting the number of visible
echoes a relative measure of system performance is achieved.
Two experimental delay line models were ordered and received from
Ultrasonics, Inc.
A test set-up utilizing a pulsed klystron, in lieu of the maggy, was con-
structed and the operation verified. Approximately 18 to 20 echoes are visible,
however, an accurate measure of system performance is not possible because of the
inaccuracy of counting the number of echoes as they disappear in the noise.
